Aims & Background. Congenital Talipes Equinovarus (CTEV) is the most common congenital musculoskeletal birth defect affecting 1 in 1000 births per annum. We have compared our surgical results to the British Society of Children's Orthopaedics (BSCOS) published guidelines. Methods. Between, 2006–16, patients who were referred for treatment of pathological CTEV were audited. Data from a combination of Clinical Portal, Orthotic Patient Administration System and Surgical Elogbook were assessed. In addition, the degree of deformity was classified by the Harrold & Walker method at the time of diagnosis (senior author). Most of this information was recorded prospectively and analysed retrospectively. Ponseti technique was the method of treatment. Results. 96 patients assessed (133 feet). There were 78 males and 18 females, 37 patients were affected bilaterally and 11 had associated syndromes. There were 23 Harrold & Walker (H&W) 1, 28 H&W 2 and 82 H&W 3 classification feet. Average time period in Ponseti boots and bars was 14.4 months (95% CI 12.9–15.9), average time in all types of bracing of was 17.1 months (95% CI 14.8–14.8). Number and rate of surgeries performed were as follows: 77 Tendoachilles release (63.1%), 19 Tibialis Anterior Transfer (5.6%), 15 Radical Release (12.3%), revision 25 Surgery (20.5%) & 5 Abductor Hallucis Release (4.1%). Conclusion. The audit confirms that the unit meets most of the current BSCOS guidelines. All surgical procedures apart from radical release surgery fall within accepted limits. This may be due, in part, to the syndromal cases. We do however demonstrate a significantly reduced average time period in bracing compared to that recommended by BSCOS. There are multiple reasons for this discrepancy including non-compliance and poor splint tolerance (child refusing to use). We feel this work demonstrates a reduced period in bracing can be achieved whilst maintaining standards of treatment

Valgus unloader knee braces are a conservative treatment option for medial compartment knee osteoarthritis (OA). These braces are designed to reduce painful, and potentially injurious compressive loading on the damaged medial side of the joint through application of a frontal-plane abduction moment. While some patients experience improvements in pain, function, and joint loading, others see little to no benefit from bracing [1]. Previous biomechanical studies investigating the mechanical effectiveness of bracing have been limited in either their musculoskeletal detail [2] or incorporation of altered external joint moments and forces [3]. The first objective was to model the relative contributions of gait dynamics, muscle forces, and the external brace abduction moment to reducing medial compartment knee loads. The second objective was to determine what factors predict the effectiveness of the valgus unloading brace. Seventeen people with knee OA (8 Female age 54.4 +/− 4.2, BMI 30.00 +/− 4.0 kg/m. 2. , Kellgren-Lawrence range of 1–4 with med. = 3) and 20 healthy age-matched controls participated in this study which was approved by the institutional ethics review board. Subjects walked across a 20m walkway with and without a Donjoy OA Assist knee brace while marker trajectories, ground reaction forces, and lower limb electromyography were recorded. The external moment applied by the brace was estimated by multiplying the brace deformation by is pre-determined brace-stiffness. For each subject, a representative stride was selected for each brace condition. A generic musculokeletal model with two legs, a torso, and 96 muscles was modified to include subject-specific frontal plane alignment and medial and lateral contact locations [4]. Muscle forces, and tibiofemoral contact forces were estimated using static optimization [4]. We defined brace effectiveness as the difference in the peak medial contact force between the braced and the unbraced conditions. A stepwise regression analysis was performed to predict brace effectiveness based on: X-ray frontal plane alignment, medial joint space, KL grade, mass, WOMAC scores, unbraced walking speed, trunk, hip and knee joint angles and moments. The OA Assist brace reduced medial joint loading by approximately 0.1 to 0.2 BW or roughly 10%, during stance. This decrease was primarily due to the external brace abduction moment, and not changes in gait dynamics, or muscle forces. The brace effectiveness could be predicted (R. 2. =0.77) by the KL grade, and the magnitude of the hip adduction moment in early stance (unbraced). The brace was more effective for those that had larger hip adduction moments and for those with more severe OA. The valgus knee brace was found to reduce the medial joint contact force by approximately 10% as estimated using a musculoskeletal model. Bracing resulted in a greater reduction in joint contact force for those who had more severe OA while still maintaining a hip adduction moment similar to that of healthy controls

To assess the outcome of Offloading Knee brace (V-VAS) in the treatment of osteoarthritis of the knee. A total of 147 patients with knee arthritis were included in this study. Eighty six patients were followed up retrospectively and 61 patients were followed up prospectively. Average follow up was about 3.4 years in retrospective group and 1.2 years in prospective group. The Oxford knee score, Pain score, Walking distance and Patient satisfaction were evaluated. Average oxford scores before the brace was 19 and after the brace was 32. The pain scores before and after the brace was 8 and 3 respectively. The walking distance had improved to 900 yards. The patient satisfaction was 78%. Thirteen of eighty six patients in the retrospective group discontinued the brace, of these two had high tibial osteotomy, six patients had total knee replacement, one had unicondylar knee replacement, one patient had dislocation of patella and two elderly patients were house-bound because of medical problems. The Off loading knee brace is effective in the management of osteoarthritis of the knee. Patient satisfaction is high when using the brace. However compliance may be an issue in some of the patients. Education and early appointment for brace re-fitting increases patient compliance. Bracing is a beneficial treatment for severe medial OA of the knee

Summary. Pyogenic spondylodiscitis is an uncommon but severe spinal infection. In majority of cases treatment is based on intravenous antibiotics and rigid brace immobilization. Posterior percutaneous spinal instrumentation is a safe alternative procedure in relieving pain, preventing deformity and neurological compromise. Introduction. Pyogenic spondylodiscitis (PS) is an uncommon but severe spinal infection. Patients affected by a non-complicated PS and treatment is based on intravenous antibiotics and rigid brace immobilization with a thoracolumbosacral orthosis (TLSO) suffices in most cases in relieving pain, preventing deformity and neurological compromise. Since January 2010 we started offering patients percutaneous posterior screw-rod instrumentation as alternative approach to TLSO immobilization. The aim of this study was to evaluate safety and effectiveness of posterior percutaneous spinal instrumentation for single level lower thoracic (T9-T12) or lumbar pyogenic spondylodiscitis. Materials and Methods. Retrospective cohort analysis on 27 patients diagnosed with PS who were offered to choose between 24/7 TLSO rigid bracing for 3 to 4 months and posterior percutaneous screw-rod instrumentation bridging the infection level followed by soft bracing for 4 weeks after surgery. All patients underwent antibiotic therapy. Fifteen patients chose conservative treatment, 12 patients chose surgical treatment. Patients were seen at 1, 3, 6, 9 months after diagnosis. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and complete blood count were measured at each follow-up visit. Segmental kyphosis was measured at diagnosis and at 9 months. VAS, SF-12, and EQ-5D questionnaires were recorded at each follow-up visit. Baseline groups’ demographic characteristics were assessed using independent sample t-tests for continuous variables and χ2 tests for frequency variables. Results. Complete healing was achieved in all patients, no difference was observed in healing time between the two groups (77.3±7.2 days vs 80.2±4.4). Instrumentation failure and screw loosening was not observed in any patient. In both group CRP and ESR decreased accordingly with response to antibiotic therapy. Surgically treated patients had significantly lower VAS scores at 1 month (3.05±0.57 in surgery group vs 5.20±1.21 in TLSO group) and 3 months (2.31±0.54 in surgery group vs 2.85±0.55 in TLSO group) post-diagnosis. Both groups had similar trends toward fast recovery in both mental (MCS) and physical components (PCS) of SF-12 questionnaire, surgically treated patients showed steeper and statistically significative improvement at 1 month (37.83±4.57 MCS in surgery group vs 24.52±3.03 MCS in TLSO group and 35.46±4.43 PCS in surgery group vs 27.07±4.45 PCS in TLSO group, p<0.001), 3 months (52.94±3.82 MCS in surgery group vs 39.45±4.92 MCS in TLSO group and 44.93±3.73 PCS in surgery group vs 35.33±6.44 PCS in TLSO group, p<0.001), and 6 months (54.93±3.56 MCS in surgery group vs 49.99±5.82 MCS in TLSO group) post-diagnosis, no statistically significant differences were detected at the other time points (9 months post-diagnosis). EQ-5D index was significantly higher in surgery patients at 1 month (0.764±0.043 in surgery group vs 0.458±0.197 in TLSO group) and 3 months (0.890±0.116 in surgery group vs 0.688±0.142 in TLSO group); no statistically significant changes were observed in segmental kyphosis between the two groups. Conclusion. Posterior percutaneous spinal instrumentation is a safe, feasible, and effective procedure in relieving pain, preventing deformity and neurological compromise. Surgical stabilization was associated with faster recovery, lower pain scores, and improved quality of life compared with TLSO conservative treatment at 1 and 3 months after diagnosis

Summary

Bi-plane Image matching method is very useful technique to evaluate the loaded 3D motion of each cervical level.

Anterior vertebral body tethering (AVBT) is a growth modulating procedure used to manage idiopathic scoliosis by applying a flexible tether to the convex surface of the spine in skeletally immature patients. The purpose of this study is to determine the preliminary clinical outcomes for an adolescent patient cohort. 18 patients with scoliosis were selected using a narrow selection criteria to undergo AVBT. Of this cohort, 11 had reached a minimum follow up of 2 years, 4 had reached 18 months, and 3 had reached 6 months. These patients all demonstrated a primary thoracic deformity that was too severe for bracing, were skeletally immature, and were analysed in this preliminary study of coronal plane deformity correction. Using open-source image analysis software (ImageJ, NIH) PA radiographs taken pre-operatively and at regular follow-up visits post-operatively were used to measure the coronal plane deformity of the major and compensatory curves. Pre-operatively, the mean age was 12.0 years (S.D. 10.7 – 13.3), mean Sanders score 2.6 (S.D. 1.8-3.4), all Risser 0 and pre-menarchal, with mean main thoracic Cobb angle of 52° (S.D. 44.2-59.8°). Post-operatively the mean angle decreased to 26.4° (S.D. 18.4-32°) at 1 week, 30.4° (S.D. 21.3-39.6°) at 2 months, 25.7° (S.D. 18.7-32.8°) at 6 months, 27.9° (S.D. 16.2-39.6°) at 12 months, and 36.8° (S.D. 22.6– 51.0°) at 18 months and 38.2° (S.D. 27.6-48.7°) at 2 years. The change in curve at 2 years post-operative was statistically significant (P=0.004). There were 4 tether breakages identified that did not require return to theatre as yet, one patient underwent a posterior spinal instrumented fusion due to curve progression. AVBT is a promising new growth modulation technique for skeletally immature patients with progressive idiopathic scoliosis. This study has demonstrated a reduction in scoliosis severity

The Cochrane Collaboration has produced five new reviews relevant to bone and joint surgery since the publication of the last Cochrane Corner These reviews are relevant to a wide range of musculoskeletal specialists, and include reviews in Morton’s neuroma, scoliosis, vertebral fractures, carpal tunnel syndrome, and lower limb arthroplasty.

Introduction. Lateral epicondylitis, also known as “tennis elbow,” is a degenerative disorder of the common extensor origin of the lateral humeral epicondyle. The mainstay of treatment is non-operative and includes physiotherapy, activity modification, bracing, nonsteroidal anti-inflammatory drugs, and injections. There is a subgroup of patients however who do not respond to non-operative measures and require operative intervention. Methods. We conducted a retrospective review of prospectively collected data to assess whether the introduction of PRP injections for lateral epicondylitis led to a reduction in patients subsequently undergoing surgical release. Results. Prior to the introduction of PRP injections, a mean of 12.75 patients a year underwent arthroscopic release for tennis elbow. Since PRP introduction this reduced to a mean of 4.25 patients a year. Using a Pearsons chi squared test this is a significant fall in the number of releases required, P<0.001. This significant reduction in patients requiring surgery since PRP introduction leads to an absolute risk reduction of 0.773 and number needed to treat on “as-treated” basis of only 1.3. Conclusion. In conclusion we consider PRP injection, for intractable lateral epicondylitis of the elbow, not only a safe but also very effective tool in reducing symptoms and have shown it has reduced the need for surgical intervention in this difficult cohort of patients
