Introduction

Snapping scapula symptoms occur due to disruption of the smooth gliding motion between scapula and thoracic cage. Patients present with pain in the scapulothoracic area aggravated by overhead and repetitive shoulder movements. It is often associated with audible and palpable crepitus, clicking, crunching, grating or snapping sensation. Open or arthroscopic scapulothoracic surgical treatment is an option when non-operative treatment modalities fail. The aim of our study was to assess the outcome of scapulothoracic arthroscopic treatment in patients with painful snapping scapula.

Surgery for DDH is one of the common paediatric orthopaedics procedures in a tertiary care paediatrics hospital.

There are no uniformly agreed guidelines about the pre-operative work up related to blood transfusion in DDH surgery. This leads to lack of uniformity in practice, sometimes causes cancellations of operations on the day of surgery (due to no cross matched blood available) and on other occasions wastage of the cross matched blood.

The aims of our study were to know the incidence of perioperative blood transfusion in a series of DDH operations and to determine what types of operations/kids have more chances of needing a blood transfusion peri-operatively.

We included all children who had surgery for DDH between April 2009 and October 2012 in our institution. We found out which of these children had blood transfusion peri-operatively and reviewed their notes to determine any trends in transfusion requirements

165 children had operations for DDH during the study period. This included operations ranging from hip open reduction to Ganz osteotomy.

6 out of 165 (4%) were transfused blood. Children needing blood transfusion tended to be older and had multiple hip operations previously. Only 3 (2 during Ganz and 1 during bilateral hip reconstruction) of these 6 children needed intra-operative blood transfusion. None of the under 4 years old children needed intra-operative blood transfusion.

We conclude that children for unilateral primary hip operations for DDH do not need pre operative blood cross match. A group and save is enough in these cases.

Introduction

The number of revision hip arthroplasty procedures is rising annually with 7852 such operations performed in the UK in 2010. These are expensive procedures due to pre-operative investigation, surgical implants and instrumentation, protracted hospital stay, and pharmacological costs. There is a paucity of robust literature on the costs associated with the common indications for this surgery.

Through the paediatric LCP Hip plating system (Synthes GmBH Eimattstrasse 3 CH- 4436 Oberdorff), the highly successful technique of the locking compression plate used in adult surgery, has been incorporated in a system dedicated to pediatrics. We are presenting the outcome of the paediatric LCP hip plating system used for a variety of indications in our institution.

We retrospectively reviewed the notes and radiographs of all those children who have had Paediatric LCP Plate for the fixation of proximal femoral osteotomy and proximal femur fractures in our institution, between October 2007 and July 2010, for their clinical progress, mobilization status, radiological healing and any complications.

Forty-three Paediatric LCP hip plates were used in forty patients (24 males and 13 females) for the fixation of proximal femoral osteotomies (n=40) and proximal femur fractures (n=3). The osteotomies were performed for a variety of indications including Perthes disease, developmental dysplasia of hip, Cerebral Palsy, Down's syndrome, coxa vara, Leg length discrepancy and previous failed treatment of Slipped Upper Femoral Epiphysis.

Twenty-five children were allowed touch to full weight bearing post operatively. Two were kept non-weight bearing for 6 weeks. The remaining 13 children were treated in hip spica due to simultaneous pelvic osteotomy or multilevel surgery for cerebral palsy.

All osteotomies and fractures radiologically healed within 6 months (majority [n=40] within 3 months). There was no statistically significant difference (p= 0.45) in the neck shaft angle between the immediately postoperative and final x-rays after completion of bone healing.

Among the children treated without hip spica, 1 child suffered a periprosthetic fracture. Of the children treated in hip spica, 2 had pressure sores, 3 had osteoporotic distal femur fractures and 2 had posterior subluxations requiring further intervention.

There were no implant related complications.

The Paediatric LCP Hip Plate provides a stable and reliable fixation of the proximal femoral osteotomy performed for a variety of paediatric orthopaedic conditions.

Ceramic-on-ceramic bearings in hip replacement have low rates of wear and are increasingly being used in young adults. Our aim was to determine the incidence of audible phenomena or other bearing-related complications.

We retrospectively analysed 250 ceramic-on-ceramic hip replacements in 224 patients which had been implanted between April 2000 and December 2007. The mean age of the patients at operation was 44 years (14 to 83) and all the operations were performed using the same surgical technique at a single centre.

At a mean follow-up of 59 months (24 to 94), the mean Oxford hip score was 40.89 (11 to 48). There were six revisions, three of which were for impingement-related complications. No patient reported squeaking, but six described grinding or clicking, which was usually associated with deep flexion. No radiological evidence of osteolysis or migration of the components was observed in any hip.

The early to mid-term results of contemporary ceramic-on-ceramic hip replacement show promising results with few concerns in terms of noise and squeaking. Positioning of the acetabular component remains critical in regard to the reduction of other impingement-related complications.

This study examined the relationship between the cross-over sign and the true three-dimensional anatomical version of the acetabulum. We also investigated whether in true retroversion there is excessive femoral head cover anteriorly. Radiographs of 64 hips in patients being investigated for symptoms of femoro-acetabular impingement were analysed and the presence of a cross-over sign was documented. CT scans of the same hips were analysed to determine anatomical version and femoral head cover in relation to the anterior pelvic plane after correcting for pelvic tilt. The sensitivity and specificity of the cross-over sign were 92% and 55%, respectively for identifying true acetabular retroversion. There was no significant difference in total cover between normal and retroverted cases. Anterior and posterior cover were, however, significantly different (p < 0.001 and 0.002). The cross-over sign was found to be sensitive but not specific. The results for femoral head cover suggest that retroversion is characterised by posterior deficiency but increased cover anteriorly.
