The FitBone lengthening nail (Orthofix UK) is an intramedullary device licensed for the lengthening of long bones in adults in the UK. It contains a motor powered by electricity transmitted via an induction coil placed underneath the skin. It was developed in Germany two decades ago but uptake in the UK has only started more recently. The aim of this study was to review the first cohort of FitBone lengthening nails in a unit with significant experience of other lengthening nails (including PRECICE and Stryde). Demographic, clinical and radiological data was prospectively collected on all FitBone cases starting in February 2022. Accuracy of lengthening rate, patient satisfaction and implant issues were all considered. Complications and learning points were recorded and discussed by the multidisciplinary team involved in the patients care.Introduction

Adjusting an external fixator can be a daunting process for patients. Despite comprehensive training, patients often request supervision for the initial adjustments which may result in a prolonged hospital stay. Following the introduction of telemedicine during the pandemic we believed that this could be utilised to support patients with their fixator adjustments. A quality improvement project was implemented to assess and evaluate a change in practice from existing Face to Face support to a telemedicine format. The aim of the project was to reduce median length of stay (LOS). The telemedicine platform was introduced in our unit from April 2021 with the change in practice. Using the life QI platform, run charts were used to record the numbers of patients whose LOS was 4 days or less. Median LOS was assessed prior to and following introduction of the telemedicine platform. Service user experience with telemedicine as well as overall training and education by the CNS team was sought through on-line questionnaires.Introduction

A greater emphasis has been placed on fracture related infection (FRI) orthopaedic practice as a separate entity in recent years. Since the publication of the FRI consensus definition and guidelines, there has been an increase in the published literature on the topic and a move towards considering FRI as separate from general orthopaedic practice and as work that requires a more specialist approach. The aim of this study was to audit current FRI practice in the UK. Orthopaedic practice related to FRI in the UK was audited using a semi-structured questionnaire. Respondents were from a range of institutions, specialties and clinical roles to reflect the multi-disciplinary nature of treating FRI. The online tool SurveyMonkey was used to share the survey at the 2022 annual meeting of the British Limb Reconstruction Society. Twenty-one questions were asked in the following domains: scope of practice, theatre and clinic capacity, availability of the multidisciplinary team, renumeration for work and scope of FRI networks.Introduction

Patients undergoing limb reconstruction surgery often face a challenging and lengthy process to complete their treatment journey. The majority of existing outcome measures do not adequately capture the patient-reported outcomes relevant to this patient group in a single measure. Following a previous systematic review, the Stanmore Limb Reconstruction Score (SLRS) was designed with the intent to address this need for an effective instrument to measure patient-reported outcomes in limb reconstruction patients. We aim to assess the face validity of this score in a pilot study. The SLRS was designed following structured interviews with several groups including patients who have undergone limb reconstruction surgery, limb reconstruction surgeons, specialist nurses, and physiotherapists. This has subsequently undergone further adjustment for language and clarity. The score was then trialled on ten patients who had undergone limb reconstruction surgery, with subsequent structured questioning to understand the perceived suitability of the score.Aims

The use of intramedullary lengthening devices is becoming increasingly popular. There are no published data regarding the incidence of venous thromboembolism following intramedullary lengthening and no reports or guidance for current practices on use of thromboprophylaxis. Following a case of post-operative deep vein thrombosis in our institution, we felt that it is important to assess best practice. We conducted this survey to collect data that would describe current practice and help guide consensus for treatment. We have identified surgeons across the UK that perform intramedullary lengthening through the British Limb Reconstruction Society membership and a Precise Users database. Surgeons were contacted and asked to respond to an online survey (SurveyMonkey - SVMK Inc.). Responses to thromboprophylaxis regimes employed in their practice and cases of venous thromboembolism were collated.Introduction

The STRYDE nail is an evolution of the PRECICE Intramedullary Limb Lengthening System, with unique features regarding its composition. It is designed for load bearing throughout treatment in order to improve patient experience and outcomes and allow for simultaneous bilateral lower limb lengthening. The literature published to date is limited with regards to both outcomes and potential issues. In this paper we report on our early experience and raise awareness for the potential of adverse effects from this device. This is a review of all patients treated in our institution using this implant. Data were prospectively recorded. We report on demographics, nail accuracy, reliability, consolidation index and cases where concerning clinical and radiological findings were encountered.Introduction

Pixel Value Ratio (PVR) is a radiographic measure of the relative density of the regenerate to the adjacent bone. This has been reported as an objective criterion for regenerate healing and a guide for when to allow full weight bearing (FWB) in lengthening with intramedullary telescopic nails. The threshold for which magnitude of PVR is adequate to allow bearing full weight is not yet agreed. The aim of this study was to identify from our cohort of adult limb lengthening patients the time to FWB following lengthening, the PVR at this point, and how this compared with the recommended values in the literature. A retrospective database review identified 30 adult patients treated with the PRECICE femoral nail by two senior authors. Time from completion of lengthening to instruction to fully weight bear was noted. The PVR was calculated for each cortex on plain radiographs taken at each postoperative visit following completion of lengthening. Significance was set at Introduction

Ring breakage is a rare but significant complication requiring revision surgery and prolonging the course of treatment. We have encountered three cases with Taylor Spatial Frames (TSF) with breakage at the half ring junction of the distal ring. This experimental study examines the strains produced at different locations on the distal ring during loading and the effects of altering the construct in order to develop techniques to minimise the risk of breakage. We mounted different TSF constructs on tibia sawbone models. Construct 1 reproducing the configuration of cases where failure was seen, Construct 2 with different wire and half pin configuration and construct 3 with the distal ring rotated 60 degrees. Strain Gauges were attached to different locations and measurements were collected during loading. Statistical analysis was subsequently performed.Introduction

Pin site care in external fixation remains a major challenge. The ideal dressing regime still remains controversial as does the type of dressing. We present an audit following the use of a sponge compression dressing in comparison to previously used sterile gauze. All pins and wires were inserted using a standardised technique. Dressings were applied during surgery to prevent haematoma formation. The new sponge dressing was applied to the wire or half-pin sites and compressed to the skin by either pierced tubing over the wire or clips at the end of the procedure. Dressings were changed weekly unless the pin sites were discharging serous fluid or frankly infected, when they were changed as required. The pin sites were evaluated for evidence of infection or irritation using the good, bad or ugly grading system. Each evaluation was performed by two of the authors on two separate occasions to assess the inter- and intra-observer error. The results were compared to those previously reported using sterile gauze as the pin site dressing. 1035 pin sites were assessed. 985 pin sites were graded as “good” (95.2%), 49 “bad” (4.7%) and 1 “ugly”. The kappa values demonstrated excellent inter- and intra-observer correlation, 0.892 and 0.905 respectively. The previous study using gauze reported 600 pin sites with 514 graded “good” (85.7%), 80 “bad” (13.3%) and 6 “ugly” (1%). The use of compression sponge dressing appears to reduce the rate of pin site irritation and infection. Further anecdotal evidence by patients who have undergone surgical treatment using both techniques demonstrated a preference for the sponge dressings due to ease of dressing change and general comfort once applied. We therefore would recommend this type of dressing in the use of external fixation.
