Volume 95-B, Issue SUPP_23 May 2013 British Limb Reconstruction Society (BLRS) AGM & Instructional Course 2013

M J Welck P Calder D Eastwood

Purpose of Study

To see if the addition of a locking plate to FD rod fixation of osteogenesis imperfecta confers extra strength and allows earlier mobilisation.

Introduction

Osteogenesis imperfecta is a heterogeneous group of disorders with congenital osseous fragility. The goal of surgery is to minimise the incidence of fracture and correct deformity. The concept of multilevel osteotomies and intramedullary fixation with a non-extendable nail was popularised by Sofield and Millar in 1959. The Bailey Dubow telescoping nail was introduced in 1963. The Fassier-Duval (FD) telescoping nail is a more recent design inserted via smaller incisions, in conjunction with percutaneous osteotomies. However there are still problems. Often the medullary canal may be too narrow to harbour a nail of adequate size for the body. Furthermore they do not give significant rotational control, which is compounded by the elasticity of the soft tissues.

The aim of the study is to evaluate how patients over 65 years of age cope with the Ilizarov method of treatment, compared with patients a decade younger.

Two age groups were selected, 50–65 years versus 65 years and over. 20 consecutive patients were recruited for each group. SF36 scores were completed pre-operatively, at 6 weeks post op and 6 weeks post frame removal. 41 patients were recruited in total.

Seven patients were lost to follow up – 2 died, 2 became too ill to continue with treatment, 3 did not complete the SF36. This left 34 patients.

T test was used to analyse the results.

Both age groups showed an equal and statistically significant drop in SF36 scores whilst the Ilizarov frame was on (p<0.01 for each group).

After frame removal, SF36 in the >65 group was not significantly different to pre-operative values.

In the younger group, SF36 after frame removal was still significantly lower than pre-operative values (p<0.01).

Age makes no difference in how patients cope with the ilizarov frame during treatment. Older patients have low pre-injury function levels, but appear to return to this level quickly after frame removal. Younger patients do not recover pre-injury function in 6 weeks after completion of treatment.

Purpose of Study

We report the outcome of five cases of chronic paediatric Monteggia lesion treated with a modified Bell-Tawse procedure.

Methods

Five patients with a chronic Monteggia lesion were treated over an eight-year period (2004–2012) at our institution. All underwent a modified Bell-Tawse procedure. The patient medical records were retrospectively analysed. We report the outcome in five patients.

Introduction

Infection following traumatic injury of the tibia is challenging, with surgical debridement and prolonged systemic antibiotic therapy well established. Local delivery via cement beads has shown improved outcome, but these often require further surgery to remove. Osteoset-T is a bone-graft substitute composed of calcium sulphate and 4%-Tobramycin, available in pellets that are packed easily into bone defects. Concerns remain regarding the sterile effluent produced as it resorbs, along with the risk of acute kidney injury following systemic absorption.

Purpose

We present outcomes of 22 patients treated with Osteoset-T.


J A Fagg B Kurian M Ahmad J A Fernandes S Jones

Purposes of the Study

To study the incidence of delayed consolidation of regenerate in children undergoing correction or lengthening of lower limb deformities using an external fixator.

Methods and Results

Between 2006 and 2011, 150 patients with lower limb deformities (excluding feet) were treated in our unit using external fixators. A retrospective review of our prospective database was carried out to identify patients with poor regenerate formation requiring bone grafting. Patients with acute fractures, pseudarthrosis of the tibia due to neurofibromatosis and those above the age of eighteen were excluded. An independent observer reviewed the medical records and radiographs.

Eleven patients with ages ranging from 2 years 5 months to 17 years 5 months (mean average 9 years 9 months) formed the basis of our study – 3 males and 8 females. Factors that were associated with this complication include age greater than twelve years (10 patients), lack of weight bearing (6 patients), previous fixator (5 patients) and smoking (5 patients). The regenerate was deficient in nine tibial segments and two femoral segments. Six of the deficient tibial regenerates were at a proximal site whilst three were distal. There was no significant difference in length gained between these sites (p < 0.5). The mean time to regenerate bone grafting was 7 months. Time to healing following bone grafting was 2.5 months.


J A Fagg E Mills S L Royston

Purpose of Study

We intended to determine our rates of deep infection and non-union in severe open tibial fractures treated at our institution with Ilizarov frames.

Methods

We retrospectively reviewed the case notes and radiographs of sixty consecutive cases of severe (Gustillo-Anderson Grade III) open fractures of the tibia treated in our tertiary referral unit with the ‘Flap and Frame’ technique. This technique involves early aggressive soft tissue and bone debridement and temporary skeletal stabilisation, followed by soft tissue coverage and then, when the soft tissues have settled, definitive skeletal stabilisation with the Ilizarov frame. The primary outcome measures were the presence of deep infection, occurence of union with the index frame, and any requirement for secondary amputation.

Tibial non-union causes significant morbidity and functional impairment. Circular frames are valuable tools in the treatment of non-union, however prolonged treatment often causes patients increased morbidity due to pin site problems together with personal and emotional strains.

The purpose of this study was to assess patient centred outcomes following treatment of tibial non-union in circular frame.

We identified 21 patients who had undergone treatment of tibial non-union using a circular frame. Patients were sent questionnaires utilising the Enneking scoring system and EQ-5D general health questionnaire. Fourteen patients responded. There were 3 females, mean age was 48.2 years. The average number of previous operations was 1.2. All patients went on to achieve union with a mean 10.1 months (6–20) in frame.

The mean Enneking score was 58.0% (34.3–77.1). Two patients were enthusiastic about their treatment, two liked it, three were satisfied, four accepted and would do it again while three accepted it but would not do it again.

The Euroqol questionnaire results showed that 8 patients had some difficulty with mobility, 10 had some difficulty with usual activities and 12 moderate pain. There was no significant difference in the EQ VAS score of overall health state for treated patients compared with predicted scores for an age and sex matched UK population (77.7 vs 83.1, p=0.07).

Our study shows that many patients undergoing limb salvage with circular frames for tibial non-union continue to have clinically significant symptoms, however the majority would undergo similar treatment again and we found no difference in overall health state compared with age and sex matched predicted scores. Circular frames are undoubtedly a valuable tool in the management of non-union however patients should be given realistic counselling regarding the treatment and expected outcome.

Statement of purpose

To demonstrate how contemplating reconstructive options among members of Orthoplastic team can prevent accidental damage during initial wound debridement in foot and ankle injuries

Complex defects of the foot and ankle often require input from plastic and orthopaedic surgeons. There are different reconstructive options but one excellent regional option for small defects is the Extensor Digitorum Brevis muscle (EDB) flap. The anatomy of the flap and surgical technique and utility are described and demonstrated through a case series.

We present a series of 4 consecutive cases of the use of the pedicled EDB flap for soft tissue coverage of difficult defects around the foot and ankle. This regional pedicled flap can be proximally based to cover defects around the ankle or distally based for distal foot coverage. When possible, it facilitates a reconstruction with minimal donor site morbidity, shorter operating times, and fewer complications than alternative options

The flap would usually be performed by the plastic surgical member of the orthoplastic team, but an understanding of it by foot and ankle and reconstructive orthopaedic surgeons is relevant as it's vascular supply via the lateral tarsal artery can be easily damaged, preventing its use in the management of wound complications or trauma.

Statement of Purpose

To compare the functional outcome of Distal Tibial Metaphyseal fracture treated with Circular frame compared vs. Locking Plate

Methods and Results

Distal Tibial Metaphyseal fractures were retrospectively identified over an 18 month period. Each fracture was assessed individually using radiographs. All paediatric, compound, tibial plateau and intra-articular fractures were excluded from the study. Other methods of fixation including intramedullary nailing were also excluded. The remaining fractures were assigned to either the circular frame fixation or the locking plate intervention group. Outcomes were assessed using radiographs for union dates and microbiology results for evidence of infection. Patients were followed up by postal questionnaires, which included a modified American Orthopaedic Foot and Ankle Score (AOFAS), the Olerud and Molander Score (O&M) and a custom questionnaire. The custom questionnaire asked about co-morbidities, smoking status and work days lost following surgery. After exclusions, 30 patients (Frame=15, Plate=15), were sent out questionnaires via post. We received completed questionnaires from 21 patients (Frame=11, Plate=10) giving us a response rate of 70%. Results show no difference in infection rates, skin necrosis, non-union or re-operation rates. There was also no significant difference in patient AOFAS and O&M scores at follow up.

Background

Chronic osteomyelitis with intramedullary sequestrum resulting in persistent infection is a challenging orthopaedic problem that often involves multiple surgical operations and unfortunately has a significant recurrence rate. Reasons for this may include difficulty in eradicating all intramedullary microsequestra making subsequent prolonged antibiotic therapy less effective. Use of the Reamer-Irrigator-Aspirator (RIA) has many advantages for management of intramedullary infections in chronic osteomyelitis. The RIA technique allows irrigation of sterile large quantities of saline with simultaneous bony debridement with very sharp reamers that are specially designed to allow simultaneous fluid aspiration.

Purpose

We will illustrate the pearls and pitfalls associated with the RIA technique, based on our experience so far.

We present the results of a new non-invasive lengthening nail enabling accurate control of the lengthening process and joint rehabilitation.

Introduction

The use of intramedullary lengthening nails have gained popularity as they reduce common complications associated with external fixators, including infection, joint stiffness, bone regenerate deformity, late fracture and patient implant acceptance. Current nails however are associated with complications including implant breakage, mechanical failure, runaway nail and requiring MUA to restart or obtain segment lengthening. The Precice nail incorporates magnet technology with a hand held device allowing non-invasive lengthening. The nail is also reversible allowing shortening if required. Physiotherapy can continue throughout treatment to maintain joint range of motion without concern of uncontrolled nail runaway. The lengthening is axial reducing shear/torsional forces on the regenerate.

Method

The lengthening of 4 femora was undertaken in 3 patients, mean age 34 yrs for post-traumatic shortening and short stature. A standard technique included an Ilizarov corticotomy followed by a 6 day latent period. Patients were mobilised partial weight bearing and knee range of motion maintained. The femora were lengthened one third of a millimetre three times per day. Radiographic and clinical review was performed every 2 weeks.

This study aims to ascertain the value of CT in assessing union of complex tibial fractures in patients treated with internal or external fixation.

Twenty patients who fit the above criteria were selected from a list of those sent for CT lower leg by the department of Orthopaedics and Trauma at the Royal Infirmary of Edinburgh from 2007–2012. The x-rays chronologically closest to the CTs were assessed by two observers, and the results evaluated for inter-observer agreement. The observers recorded their general impression of whether there was adequate union for fixation removal, and scored the x-rays using the Radiographic Union Scale for Tibial fractures (RUST). There was fair agreement on “general impression” (kappa 0.36, 95% CI 0.08 to 0.64), but there was good agreement using the RUST score (ICC 0.81 95CI 0.12 to 0.96). However, only 45% of the x-rays could be rated by both observers due to obstruction from metalwork. The CT scans were assessed by two orthopaedic surgeons, first giving a general impression of whether there was adequate union for fixation removal, then using a modified RUST score. The inter-observer agreement was moderate in the former (kappa 0.55, 95% CI 0.18 to 0.89) and substantial in the latter (ICC 0.78 95% CI 0.40 to 0.92); only one image was unable to be assessed due to artefact.

The author concludes that CT was useful in these patients due to the high number of x-rays in which cortices were obstructed by metalwork. Use of the RUST score improved inter-observer agreement, and would therefore be useful in both future studies and inter-departmental clinical communication. Further research is needed to relate use of the modified RUST score to clinical outcome.

A statement of the purposes of the study

This study examined the stability of two different hexapod frames at increasing strut angles and the possible use of an additional strut to aid stability.

Introduction

Hexapod frames have certain advantages over standard circular frames, however disadvantages include a rattle and instability at some strut angles. This could be particularly important when larger diameter rings are used over a shorter distance resulting in lower ring strut angles such as in the femur.

Purpose

Assess and report the functional and post-operative outcomes of complex acute radial head fractures with elbow instability treated by arthroplasty using an uncemented modular anatomic prosthesis.

Methods

Over a 3-year period (2007–2010), 21 patients (mean age 51.9 years) were treated primarily with modular radial head arthroplasty (mean follow up of 27.1 months). Data was collected retrospectively using clinical notes, operation documentation and prospectively using validated scoring systems namely the Oxford Elbow Index, Quick DASH and the Mayo Elbow Performance Score. Associated elbow fractures, ligamentous injury and short to mid term post-operative outcomes including radiographic assessment were recorded.

Previous reports have shown the efficacy of muscle interposition grafts in treating recalcitrant infection in the presence of hip arthroplasty. We report our experience with a two stage debridement and rectus femoris pedicled interposition graft technique in chronic severe native hip infection with a persistent draining sinus.

During the last 16 months, three paraplegic patients presented with persistently draining sinuses and chronic osteomyelitis of the pelvis, acetabulum and proximal femur, in a total of four hips. The mean patient age was 49 years (range, 40 to 59 years). In all patients there had been previous attempts to control the infection with wound debridement and long-term antibiotics.

A two-stage operative treatment was used in all patients. The first stage comprised wound debridement, washout, gentamycin-bead application and temporary vacuum assisted wound coverage.

At the second stage, approximately ten days later, through a standard anterior midline incision, the rectus femoris muscle was elevated on its pedicle, rolled, transposed into the acetabulum and sutured to the transverse acetabular ligament. At the second stage, all patients had local administration of antibiotics with genetamycin impregnated absorbable collagen fleece and all wounds were closed by delayed primary closure with a negative pressure dressing placed over the closed wound. All patients were commenced on a 6 week course of intravenous antibiotics, according to sensitivities.

No loss of flap occurred in any of the patients. One wound had partial dehiscence and required a split skin graft. At the final follow-up examination all the wounds were healed and there was no recurrence of draining sinuses, pressure sores or systemic sepsis.

The two stage technique with a pedicled rectus femoris interposition graft may be a useful technique for the treatment of complex chronic persistent osteomyelitis of the pelvis, acetabulum and proximal femur, with the primary aim of stopping the discharging sinus.

Statement of purpose

To determine the outcome of the use of Bone Morphogenetic Protein 7 (BMP7) as a replacement for bone graft in a limb reconstruction unit

Methods

Retrospective case note and imaging review was performed on a cohort of 71 consecutive patients from October 2009 to October 2012 in whom BMP7 was used to achieve union. The patients were identified from a pharmacy database. Factors analysed included the perceived indication, location in the skeleton, age, comorbidities, type of procedure (non-union, fusion, docking site etc), complications and need for revision surgery.

Statement of purpose

To determine whether the amount of fibula resection in fibula osteotomy influences outcome in deformity correction surgery.

Methods

Retrospective case note and imaging review was performed on a cohort of 45 patients from November 2005 to July 2009 treated with lengthening and/or correction for leg deformity in either an adult or paediatric limb reconstruction centre. Method, extent and level of original fibular resection was recorded, as well as type of fixator, distraction regime and total gap at osteotomy site after distraction. Outcome was measured as premature, expected or non-union and subsequent need for reintervention.

Statement of purpose

To describe the results and technique of ankle fusion following failed Total Ankle Replacement (TAR) in a limb reconstruction unit.

Methods

Retrospective case note, microbiology and imaging review was performed on four consecutive patients referred to the limb reconstruction unit for salvage of infected total ankle replacement surgery since 2009. The patients were identified from operative list and tertiary referral records. A review of the current literature regarding TAR was performed.

The purpose of this study was to quantify the effect of BMP 7 and recombinant Human (rh) BMP 2 at stimulating bone formation and bone union in trauma and elective orthopaedic surgery.

Methods

We retrospectively reviewed the use of BMP 7 and rhBMP 2 at the Queen Alexandra Hospital between 2005 and 2012. The minimum follow up was three months. Inclusion criteria consisted of all patients who had failed to achieve previous surgical bone union and then received either BMP 7 or rhBMP 2 in an attempt to achieve bone union (as part of revision surgery). Patients who have not completed a minimum of three months follow up were excluded. Bone union was defined clinically and radiographically.

Results

17 patients were included (9 elective and 8 trauma patients). 9 patients received BMP2 (8 trauma and 1 elective) and 8 received rhBMP 2 (all elective). The average number of attempted fusions with autogenous bone graft prior to the use of BMP agent in the trauma and elective group was 2 and 3 respectively. The overall union rate following the use of BMP was 94.1%. 1 patient from the BMP 7 group (trauma patient) failed to unite. The union rate with BMP 7 and rhBMP 2 was 88.9% and 100% respectively. Following the use of BMP the average time to union was 117 days (BMP 7 124 days and rhBMP 2 112 days).

A high volume of trauma and limited resources means that traditional methods of bone reconstruction are not feasible in parts of Africa. We present the management and outcomes of using Masquelet's concept, of an induced membrane and secondary morcellised cancellous bone grafting, in patients with severe lower limb trauma.

Eleven patients were treated in an orthopaedic department in rural southern Africa between 2011 and 2012. This is a subgroup that is part of a larger study of open fractures that received ethical approval.

All patients were male, with ten aged between 20 and 35 and one aged 70. Two were HIV positive. There were three open femur and eight open tibia fractures. Three required fasciocutaneous flaps and one required a muscle flap to achieve adequate soft tissue coverage. Eight cases were performed as the primary treatment and three were to treat septic non-unions. Bone defects ranged from 4 to 10 cm. Definitive bony stabilisation was maintained by mono-lateral external fixator in three patients. In other cases this was converted to a circular frame or internal fixation.

The results have been mixed. In three patients bone grafting was delayed due to wound or pin site problems. In one case the bone graft was lost due to infection but repeating the procedure produced a good result. Time to bony union in each case is difficult to quantify. However, there is clear evidence of new bone forming in most cases. Four patients are weight bearing with external fixation removed, as are five patients with internal fixation. In a few cases bony union appears to be taking significantly longer, if at all.

Masquelet technique is a welcome addition to the options available in bone reconstruction. However, time to achieve bony union is unpredictable. Refinement of the technique for use in the developing world is needed.

Ilizarov frame removal often occurs in the outpatient setting, and previous data has shown it can be a painful experience. Frames with a total of four or more olive wires or half-pins in combination yielded increased pain scores at frame removal.

Sublingual fentanyl provides rapid onset, short acting analgesia for painful procedures such as dressing changes in burns patients. We hypothesised that administration of sublingual fentanyl, prior to frame removal would improve patients' pain scores.

Twenty-one patients were given 100 mcg sublingual fentanyl prior to frame removal. Their pain scores were documented on an 11-point (0–10) numeric visual scale before, immediately after, 15 and 30 minutes after frame removal, and the following day. The same nurse specialist removed all the frames. Nitrous oxide was available for patients if they needed further analgesia.

The majority of frames were removed from tibia. The average patient age was 40.8 years. Each frame had a median of 9 wires (range 2–17), and 4 olives (2–8). Eight frames had half pins (range 1–4, median 2). Fourteen patients used nitrous oxide in addition to fentanyl.

Overall, the average pain score was 3.1. This peaked at 7.5 immediately after frame removal, but 15 minutes following removal the average was 2.5. Patients who had supplementary nitrous oxide had higher pain scores throughout (though not beforehand), although these differences were not statistically significant.

Four patients (19%) reported adverse effects following administration, but none required medical intervention.

Patients' pain scores averaged 2.52 within 15 minutes of removal, compared with 5.25 from our previous review. This suggests that fentanyl may be beneficial in frame removal, but our sample size was small, and more research is needed in this area.

Purpose

The correction obtained in the coronal plane knee deformity using guided growth was assessed in children with sick physes (Height<1SD of the normal children) to define the limits of this technique in sick physis

Methods

We retrospectively assessed deformity correction following guided growth using 8 plates in children with coronal plane deformity and metabolically abnormal physis- renal rickets in 6 and bone dysplasias (multiple epiphyseal dyspasia, spondyloepiphyseal dysplasia, metaphyseal dysplasia, mesomelic dysplasia, chondrodysplasia punctata) in 10 children aged 2 to 14 years. Lateral distal femoral angle(LDFA) and medial proximal tibia(MPTA) angles were serially assessed after eight plate application as a day care procedure. We noted correction achieved rate of correction, complications and additional surgical procedures. Fischer's exact test and multiple regression analysis was done to assess the effect of modifiers.

Osteoid osteoma is a benign bone-forming lesion, characterized by its small size, its clearly demarcated outline and by the usual presence of a surrounding zone of reactive bone formation. It often poses a diagnostic challenge due to its ambiguous presentation. The aetiology of osteoid osteoma is poorly understood. The previous suggestion that osteoid osteoma was not associated with trauma or infection has been challenged by more recent literature raising the possibility that it could be a reactive or healing response or a phenomenon associated with the revascularisation process. This case report describes an unusual presentation of a post-traumatic osteoid osteoma. Two years following a diaphyseal, spiral tibial fracture treated nonoperatively, the patient developed new pain at the previous fracture site. The pain was constant, relieved by non-steroidal analgesia and not associated with systemic upset. It was initially attributed to other more likely diagnoses such as osteomyelitis and neuropathic pain. Multiple investigations and interventions were undertaken prior to the definitive diagnosis being obtained by surgical excision of the lesion and histological studies five years after the injury and three years following the initiation of the discomfort. In both English and foreign language literature there are only seven case reports that document osteoid osteoma following fracture, these are predominantly in the lower limb with no predominance to operative or nonoperative management. This case report should raise the index of clinical suspicion of osteoid osteoma occurring post fracture.

The Pelvic Support Osteotomy (PSO) or Ilizarov Hip Reconstruction(IHR) is well described for the treatment of septic sequelae of infancy. The purpose of this study was to clinically, functionally and radiographically assess our short-term results of this procedure.

25 patients (16 boys, 9 girls) who had undergone a IHR using the Ilizarov/TSF construct over a period of 10 years for a variety of pathologies were reviewed. The mean age at surgery was 15 years 4 months. The pre-operative diagnoses were SCFE(10), hip sepsis (6), DDH (6) and Perthes (3). All had significant leg length discrepancies, 16 had a painful stiff hip, 6 had a painful mobile hip and 3 had a painless unstable hip. At surgery, a mean measured proximal valgus angle of 51° and a mean extension angle of 15° was achieved. Distal femoral lengthening averaged 4.2 cm and distal varus correction was a mean of 8°. The mean fixator time was 173 days.

At a mean of 2 years and 7 months follow-up the lower-extremity length discrepancy had improved from a mean of 5.6 cm apparent shortening to 2.3 cm. Trendelenberg sign was eliminated in 18/25 cases. Improvements in range of hip movements and gait parameters were observed. Stance time asymmetry, step length asymmetry, pelvic dip and trunk lurch improved significantly. One patient had conversion to a total hip replacement after 7 years, 4 patients required re-do PSO due to remodelling of the proximal osteotomies, two had heterotopic ossification and two had significant knee stiffness due to lack of compliance.

The early results of IHR are encouraging to equalise limb lengths, negate trendelenburg gait, provide a mobile hip with a reasonable axis and the possibility of conversion to THR in the future if needed. Complications need to be anticipated and the effects of remodelling and maintaining adequate knee range of motion must be emphasised.


SK Chilbule V Dutt AD Gahukambale V Madhuri

Purpose

We retrospectively evaluated the outcome of fibula grafts in upper limb post infectious diaphyseal gap nonunions and assessed the following modifiers: age, site, vascularised/ nonvascularised, and length of the graft on time to union, graft incorporation, complication rate and reoperation rate.

Methods

Thirty seven paediatric upper limb segmental defects treated over a period of 10 years were identified. Twenty two post septic defects in 21 children were treated with intramedullary fixation and vascularised/ nonvascularised fibula grafting. Union time was assessed from records and radiographs. Graft incorporation was assessed using Pixel value ratio (Hazra et al). Complications were defined as nonunion, delayed union, implant failure, refractures, graft loss and infection.


J Ferguson M Sutherland H Pandit M McNally

Purpose

According to the National Institute for Clinical Excellence (NICE) a risk assessment for venous thromboembolism (VTE) should be conducted on all patients undergoing elective orthopaedic surgery. We looked at the patient outcome undergoing elective Ilizarov surgery in terms of symptomatic VTE occurring during or after frame management.

Methods

We performed a retrospective chart review of all adult Ilizarov cases performed by a single surgeon between 2000–2011. Patient mortality was confirmed using the Demographics Batch Service.

The purpose of this study was to assess the impact of Ilizarov frame fixation and total contact casting on the complications of Charcot arthropathy.

The diabetic charcot foot or ankle is a potentially limb threatening disorder. This progressive disorder is characterised by osteopenia, bone fragmentation and joint subluxation. The risk of significant deformity and osteomyelitis lead to high rates of amputation in these patients.

We analysed patients with acute charcot arthropathy attending the Rowley Bristow Unit between 2008 and 2012. We assessed 48 patients with a mean age of 59 years. Mean follow up was 24 months. 12 patients were managed with Ilizarov frame fixation and 36 using total contact casting. The duration of management was determined using serial infrared temperature monitoring to ensure the temperature of the limb normalised before patients were deemed safe to remove their immobilisation. The mean duration of Iliazarov frame fixation was 6.2 months and 5.3 months duration for total contact casting. In the Ilizarov group pin site infections were common and treated with a short course of antibiotics. In total one patient required below knee amputation following Ilizarov frame fixation. No patients suffered with osteomyelitis.

We feel that prompt management of acute charcot arthropathy with either total contact casting where appropriate or Ilizarov frame fixation can reduce serious complications of this disorder.

Ultrasound treatment can be used as an alternative to surgical methods for treating non-union or to enhance healing in a delayed union. This study presents our short-term results of using low intensity pulse ultrasound stimulation in long bone non-union. 18 patients with surgically treated long bone non-union were treated using the Exogen® ultrasound stimulator (Smith & Nephew Inc., UK). The average age of patients was 48 years (20–73 yrs). There were 8 femur fractures, 9 tibial fractures and 1 knee arthrodesis. 5 of these patients had infected non-union. The average follow up after initiation of treatment was 4 months (range 2–8 months). They received 20 minutes stimulation daily at the fracture site with regular follow up in clinic. We reviewed their serial radiographs and clinical progress. The mean interval to initiation of the ultrasound treatment was 7.9 months (2–27 months). Complete bony union was obtained in 6 of the 18 cases (33%) within 4 months of initiation of treatment. In 7 of 18 cases (38%) there was good evidence of progress towards bony union, while in 4/18(22%) patients there was no progress towards union at average of 4 months (range 2–8 months). There were no complications noted with this treatment. Most non-unions are treated by surgical revision, with consolidation rates ranging from 85 to 100% according to previous studies. Our study suggested 72% patients showing progress towards union with 33% achieving bony consolidation at 4 months. Patients with infected non-union also benefitted from this treatment. In summary ultrasound treatment can be a viable option to treat long bone non-unions, which may avoid the morbidity and complications associated with surgery.

We would like to present this case series of 10 adolescent patients with displaced, closed diaphyseal tibial fractures managed using the Taylor Spatial Frame.

Management options for these injuries include non-operative treatment, antegrade nailing, flexible nailing systems, plating and external circular fixation. External circular fixation allows anatomical reduction avoiding potential complications such as growth arrest associated with antegrade nailing and retained metal work with plating. Flexible nailing system and cast immobilisation are unreliable for precise anatomical reduction. With limited evidence as to the extent of post-traumatic deformity that is acceptable, combined with the limited remodeling potential that this patient group possess, the precision of percutaneous fixation with the Taylor Spatial Frame system has clear advantages.

This is a retrospective analysis of 10 adolescent patients with a mean age of 14.5 years (range 13 to 16 years). Data collected includes fracture configuration, deformity both pre and post operatively compared to post frame removal, length of time in frame and complications. The data was gathered using the patient case notes and the Picture Archiving and Communications System. The mean time in frame was 15.5 weeks (range 11 to 22 weeks). One non-union in a cigarette smoker was successfully managed with a second Taylor Spatial Frame episode.

Our conclusion was that with careful patient selection the Taylor Spatial Frame allows successful treatment of closed tibial fractures in adolescents, avoiding complications such as growth arrest and post-traumatic deformity as well as avoiding retained metalwork.

We would like to present this service evaluation of Taylor Spatial Frame use within a busy limb reconstruction unit.

We present a cohort of 60 patients representing a year of work from January 2011 to January 2012 with a breakdown of coding data. Included are details of operative episodes, length of stay, outpatient follow up including software programming episodes, strut changes and general frame care from our specialist nurses. We have produced a comparison of cost to HRG coding tarifs with an audit of coding errors and cost implications of these corrections. Also included is a breakdown of comparison data from patients undergoing frame assisted deformity correction and internal fixation, Computer Hexapod Assisted Orthopaedic Surgery.

Exact and careful coding of these procedures is required considering their relatively high cost.

To evaluate the efficacy of bone marrow derived stromal cells (BMSC) for the treatment of non-unions in fractures.

Methods

An ethically approved single centre randomised control trial recruited 35 patients for treatment of non-unions with BMSC during 2006–2010. Autologous BMSC were culture expanded at the Good Manufacturing Practice (GMP) standard Oscell® laboratory in the hospital. Following in vitro expansion- cells in autologous serum and serum alone were randomised for insertion at one of the two fracture sides by StratOs® computer software. Patients and the operating surgeon were blinded to the side of cell insertion. Such method of randomisation created internal controls at the fracture sites- one side receiving the cell (‘test side’) and other, not (‘control’). Serial radiographs extending up to an average of twelve months were evaluated by six independent assessors blinded to side of cell insertion. Callus formation and bridging of fracture was compared for ‘test’ and ‘control’ side. Radiological and clinical outcome at final follow-up was also noted.
