Keywords. Complete Abductor Detachament, Direct Lateral Approach, Abductor Insuffenciency, Hip Arthroplasty. Backgroung. Approach of Total hip replacement (THR) is a very important part of the surgery, the approach dictates the postoperative complications. Lateral approach is one of the most commonly used approaches. The initial lateral approach relied on bony (trochanteric) osteotomy which was later modified to tendon detachment, there are many versions of the lateral approach but the main goal is to detach the hip abductors mechanism to gain access to the underlying joint. One of the modifications is to completely detach the abductors tendon, this offers superior exposure compared to the traditional partial detachment (Hardinge) approach. Objectives. We aimed to perform the first study comparing the complications rate following complete detachment of hip abductors to the documented complications rate of the traditional approach. Study Design & Methods. Retrospective study to evaluate the rate of approach specific complications following complete abductor detachment approach, we included s all patients who had THR using this approach 8–18 months ago. The study group comprised of 44 patients of different age groups and genders. Patients were reviewed to assess gait abnormality, abductor weakness with Trendlenberg test, lateral trochanteric pain (LTP) and heterotopic ossification (H.O). Results. Out of the 44 patients in our study group 20 patients had abductor weakness with positive Trendelnberg test (45.5%) while the reported percentage of abductor weakness following the traditional approach is 4–20%.7 patients (15%) were dissatisfied with the postoperative gait. LTP was reported in 5 patients (11%) compared to 4.9% associated with standard lateral approach. In our series 9 (20.4%) patients had H.O which is within the acceptable range (up to 25%). Conclusions. Complete abductor detachment approach offers better exposure and quicker alternative to the traditional lateral approach of the hip (Hardinge) but on the other hand it has relatively higher complication rate

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

Objectives

The aim of this study was to systematically review the literature on measurement of muscle strength in patients with femoroacetabular impingement (FAI) and other pathologies and to suggest guidelines to standardise protocols for future research in the field.

Bone surface strains were measured in cadaver femora during loading prior to and after resurfacing of the hip and total hip replacement using an uncemented, tapered femoral component. In vitro loading simulated the single-leg stance phase during walking. Strains were measured on the medial and the lateral sides of the proximal aspect and the mid-diaphysis of the femur. Bone surface strains following femoral resurfacing were similar to those in the native femur, except for proximal shear strains, which were significantly less than those in the native femur. Proximomedial strains following total hip replacement were significantly less than those in the native and the resurfaced femur.

These results are consistent with previous clinical evidence of bone loss after total hip replacement, and provide support for claims of bone preservation after resurfacing arthroplasty of the hip.
