The purpose of this study was to determine whether there have been changes in the complexity of femoral fragility fractures presenting to our Dunedin Orthopaedic Department, New Zealand, over a period of ten years. Patients over the age of 60 presenting with femoral fragility fractures to Dunedin Hospital in 2009 −10 (335 fractures) were compared with respect to demographic data, incidence rates, fracture classification and treatment details to the period 2018-19 (311 fractures). Pathological and high velocity fractures were excluded. The gender proportion and average age (83.1 vs 83.0 years) was unchanged. The overall incidence of femoral fractures in people over 60 years in our region fell by 27% (p<0.001). Intracapsular fractures (31 B1 and B2) fell by 29% (p=0.03) and stable trochanteric fractures by 56% (p<0.001). The incidence of unstable trochanteric fractures (31A2 and 31A3) increased by 84.5% from 3.5 to 6.4/10,000 over 60 years (p = 0.04). The proportion of trochanteric fractures treated with an intramedullary (IM) nail increased from 8% to 37% (p <0.001). Fewer intracapsular fractures were treated by internal fixation (p<0.001) and the rate of acute total hip joint replacements increased from 13 to 21% (p=0.07). The incidence of femoral shaft fractures did not change significantly with periprosthetic fractures comprising 70% in both cohorts. While there has been little difference in the numbers there has been a decrease in the incidence of femoral fragility fractures likely due to the increasing use of bisphosphonates. However, the incidence of unstable trochanteric fractures is increasing. This has led to the increased use of IM nails which are increasingly used for stable fractures as well. The increasing complexity of femoral fragility fractures is likely to have an impact on implant use, theatre time and cost.
Less invasive single-rod fusion technique may be indicated in the management of NMS to minimise operative time, blood loss and wound-related complications. This retrospective 12-year cohort study (2008–2020) aims to evaluate and compare the outcomes of this technique to the current standard dual rod technique to determine their safety and efficacy. 28 patients in the single rod group (Mean age = 16.4 [SD ±4.0]) and 30 in the double rod group (Mean age = 16.3 [SD±3.5]). Indications included a minimum 2 year follow period, detailed information on the type of implant and a complete pre- and post-operative imaging and medical records. Baseline demographics, comorbidities, and surgical characteristics were collected. Outcomes assessed included the immediate post-op and final follow up angles and general complications. All outcome analysis was performed using a regression approach. Angles at final follow-up: lumbar (Difference ratio (DR)= 2.60 [95% CI 0.37 – 18.4], p=0.25), thoracic (DR= 1.08 [95% CI 0.19 – 6.28], p=0.92), thoracolumbar (major curve angle) (DR 1.35 [95% CI 0.60 – 3.06], p=0.46) and kyphosis (DR = 0.97 [0.66, 1.42] p=0.86). There was no statistically significant difference, between the two groups, for any of the above angle outcomes as well as for length of surgery, blood loss and complication outcomes. Both single and double rod instrumentation achieves satisfactory and safe deformity correction which is maintained at final follow up. A larger scale study is warranted to further assess these techniques while also conducting a cost-benefit analysis between them.
Whether a combined anteroposterior fusion or a posterior-only fusion is more effective in the management of patients with Scheuermann’s kyphosis remains controversial. The aim of this study was to compare the radiological and clinical outcomes of these surgical approaches, and to evaluate the postoperative complications with the hypothesis that proximal junctional kyphosis would be more common in one-stage posterior-only fusion. A retrospective review of patients treated surgically for Scheuermann’s kyphosis between 2006 and 2014 was performed. A total of 62 patients were identified, with 31 in each group. Parameters were compared to evaluate postoperative outcomes using chi-squared tests, independent-samples Aims

In response to the COVID-19 pandemic, there was a rapidly implemented restructuring of UK healthcare services. The The Royal National Orthopaedic Hospital, Stanmore, became a central hub for the provision of trauma services for North Central/East London (NCEL) while providing a musculoskeletal tumour service for the south of England, the Midlands, and Wales and an urgent spinal service for London. This study reviews our paediatric practice over this period in order to share our experience and lessons learned. Our hospital admission pathways are described and the safety of surgical and interventional radiological procedures performed under general anaesthesia (GA) with regards to COVID-19 in a paediatric population are evaluated. All paediatric patients (≤ 16 years) treated in our institution during the six-week peak period of the pandemic were included. Prospective data for all paediatric trauma and urgent elective admissions and retrospective data for all sarcoma admissions were collected. Telephone interviews were conducted with all patients and families to assess COVID-19 related morbidity at 14 days post-discharge.Introduction
Methods
Intraoperative 3D navigation (ION) allows high accuracy to be achieved in spinal surgery, but poor workflow has prevented its widespread uptake. The technical demands on ION when used in patients with adolescent idiopathic scoliosis (AIS) are higher than for other more established indications. Lean principles have been applied to industry and to health care with good effects. While ensuring optimal accuracy of instrumentation and safety, the implementation of ION and its associated productivity was evaluated in this study for AIS surgery in order to enhance the workflow of this technique. The aim was to optimize the use of ION by the application of lean principles in AIS surgery. A total of 20 consecutive patients with AIS were treated with ION corrective spinal surgery. Both qualitative and quantitative analysis was performed with real-time modifications. Operating time, scan time, dose length product (measure of CT radiation exposure), use of fluoroscopy, the influence of the reference frame, blood loss, and neuromonitoring were assessed.Aims

Many hospitals do not have a structured process
of consent, the attainment of which can often be rather ‘last-minute’
and somewhat chaotic. This is a surprising state of affairs as spinal
surgery is a high-risk surgical specialty with potential for expensive
litigation claims. More recently, the Montgomery ruling by the United
Kingdom Supreme Court has placed the subject of informed consent
into the spotlight. There is a paucity of practical guidance on how a consent process
can be achieved in a busy clinical setting. The British Association
of Spinal Surgeons (BASS) has convened a working party to address
this need. To our knowledge this is the first example of a national
professional body, representing a single surgical specialty, taking such
a fundamental initiative. In a hard-pressed clinical environment, the ability to achieve
admission reliably on the day of surgery, in patients at ease with
their situation and with little likelihood of late cancellation,
will be of great benefit. It will reduce litigation and improve
the patient experience. Cite this article:
We propose a simple classification for adolescent idiopathic scoliosis (AIS) based on two components which include the curve type and shoulder level and suggest a treatment algorithm for AIS. Few Classification systems for adolescent idiopathic scoliosis (AIS) have helped in communicating, understanding and selecting a treatment for this condition; however, most of these classifications are complex and include many subtypes, making it difficult for the orthopaedic surgeon to use them in clinical practice. The variable reliability and reproducibility of these studies make recommendations and comparisons between various operative treatments a difficult task. Furthermore, none of these classifications has taken the shoulder imbalance into account, despite its importance as a clinical parameter and outcome measure.Purpose of the study
Introduction
Tapping the radial side of the wrist normally elicits a reflex contraction producing elbow flexion, wrist extension and wrist radial deviation. An abnormal response, consisting of finger flexion when performing this manoeuvre is known as the inverted radial (supinator) reflex (IRR). The significance of this reflex in asymptomatic subjects is unknown. To document the frequency of the IRR in an asymptomatic population and to identify any presymptomatic pathology in those subjects. The study group consisted of patients and staff at the senior author's institution. Patients were taken from clinics where the complaints were of lower limb symptoms. Subjects were excluded if they had any history of neck pain or stiffness or if they had any subjectively abnormal sensation. The radial reflex was elicited with a tendon hammer. Those subjects with an IRR were asked to attend for a MRI scan of the cervical spine to investigate for any abnormality. 47 subjects were studied. There were 8 subjects who displayed an IRR. In 4 subjects the IRR was unilateral and in 4 bilateral. Seven subjects consented to further investigation by MRI. The average age of these patients was 36 years. The MRI scans revealed normal appearances in 6 cases. There was no cord signal abnormality in any case. The IRR occurred with a frequency of 17% in the study group. There was no significant cervical pathology identified in these subjects. In young asymptomatic patients, the presence of an inverted radial reflex is of no diagnostic relevance.
AO Spine Reference Centre & Institute of Health & Biomedical Innovation, Queensland University of Technology, Brisbane, Australia Traumatic spinal cord injury (SCI) is a devastating condition with no curative therapy. Pro-inflammatory therapy has been suggested recently to try and reduce the inhibitory glial scar and promote neural regeneration and healing. The aim of this study is to investigate the potential of sustained delivery of angiogenic/pro-inflammatory growth factors to reduce the secondary degeneration after spinal cord injury. Adult male Wistar Kyoto rats (200-300g; 12-16weeks old) were subjected to cord hemisections via a T10 laminectomy. Animals were randomised to treatment or control groups after the spinal cord injury had been induced. Treatment consisted of implantation of a mini-osmotic pump capable of delivering 5 micrograms vascular endothelial growth factor (VEGF) and 5 micrograms platelet-derived growth factor (PDGF), via a catheter, to the site of the lesion, over 7 days(n=6). Control animals were subjected to either cord lesion only (n=6) or lesion plus mini-pump delivering PBS (phosphate-buffered saline) solution (n=6). Rats were sacrificed at one month and the spinal cords were harvested and examined by immunohistology, using anti-neurofilament-200 and anti-Glial Acidic Fibrillary Acidic Protein (GFAP) antibodies. RESULTS: Active treatment spinal cords showed a higher level with aboration of the axonal filament through the defect and more dense neurofilament-200 staining at the lesion site compared to both control groups. The treatment also showed the elevated presence of activated microglia in the lesion, whilst distal to the lesion the microglia and astrocytes retained an unreactive phenotype. Pro-inflammatory therapy in the rat spinal cord-injury model showed favourable histological findings after sustained delivery of PDGF and VEGF
The aim of this study was to evaluate the impact of a preoperative education programme on length of hospital stay for primary and revision knee arthroplasty patients. The programme was introduced at our hospital in October 2006 to encourage patients to play an active role in their postoperative recovery process. It was delivered by a multi-disciplinary team consisting of an arthroplasty nurse, ward physiotherapist, occupational therapist and orthopaedic consultant. Patients were educated about their care pathway, knee surgery, pain management, the expected discharge goal, post operative inpatient and outpatient rehabilitation. Data was prospectively reviewed for 472 patients who underwent (primary or revision) knee arthroplasty for the period between January 2006 and November 2007. There were 150 patients in the Conventional group and 322 patients in the Educational group. The mean length of stay reduced significantly from 7 days in the Conventional group to 5 days in the Education group (P<
0.01). In addition 20 percent more patients were discharged early (within 1 to 4 days) in Education group compared to the Conventional group (P<
0.01). There was no statistically significant difference in the percentage of inpatient complications and readmissions between the two groups. Our study demonstrates that preoperative education is a safe and effective method of reducing length of stay for knee arthroplasty patients. Significantly more patients achieved discharge within four postoperative days.
Seven out of 22 children with monarticular juvenile rheumatoid arthritis (MJRA) developed involvement of other joints between six months and three and a half years from the onset. In the other 15 patients the disease has remained monarticular for between one and 16 years (mean six years). Chronic iridocyclitis was seen in three of the five boys, two with antinuclear antibodies. Children with MJRA and antinuclear antibodies should have periodic ophthalmic assessment. Synovial biopsy was of value primarily in excluding other cases of arthritis, but there was only limited correlation between the histological findings and the subsequent course of the disease.
