Aims

Complex total hip arthroplasty (THA) with subtrochanteric shortening osteotomy is necessary in conditions other than developmental dysplasia of the hip (DDH) and septic arthritis sequelae with significant proximal femur migration. Our aim was to evaluate the hip centre restoration with THAs in these hips.

Hip and groin injuries are common in athletes who take part in high level sports. Adductor muscle tendon injuries represent a small but important number of these injuries. Avulsion of the tendons attached to the symphysis pubis has previously been described: these can be managed both operatively and non-operatively. We describe an uncommon variant of this injury, namely complete avulsion of the adductor sleeve complex: this includes adductor longus, pectineus and rectus abdominis. We go on to describe a surgical technique which promotes a full return to the pre-injury level of sporting activity.

Over a period of ten years, 15 high-level athletes with an MRI-confirmed acute adductor complex avulsion injury (six to 34 days old) underwent surgical repair. The operative procedure consisted of anatomical re-attachment of the avulsed tissues in each case and mesh reinforcement of the posterior inguinal wall in seven patients. All underwent a standardised rehabilitation programme, which was then individualised to be sport-specific.

One patient developed a superficial wound infection, which was successfully treated with antibiotics. Of the 15 patients, four complained of transient local numbness which resolved in all cases. All patients (including seven elite athletes) returned to their previous level of participation in sport.

Introduction

Hip and groin injuries are common in athletes participating in high level sports. Adductor muscle tendon injuries represent a small but important number of these injuries. Avulsion injuries involving tendons attaching to the symphysis pubis have previously been described and can be managed both operatively and non-operatively.

The aim is to describe a rare variant of this injury; complete avulsion of the adductor sleeve complex including adductor longus, pectineus and rectus abdominus. A surgical technique is then outlined which promotes a full return to pre-injury level of sporting activity.

Aim: To review our experience with epiphysiodesis using three different methods to correct LLD and to establish the efficacy of these procedures.

Method: A retrospective review of 42 patients from 1999 to 2008 with at least one year follow-up recorded type and location of the epiphysiodesis, average operating time and hospital stay, complications, method of prediction, timing and the final LLD. CT scanograms and mechanical axis view with grids were used to assess LLD.

Results: Epiphysiodesis was as per Canale for 26, by Metaizeau screw in 14 and by staples in 2. Average operation time was 42 minutes for Canale type, 45 minutes for the screws and 56 minutes for the staple cases. The pre operative LLD of 3.7 cms In the Canale group, improved to 1.2 cms over an average follow-up of 2.1 yrs. There were 4 minor and 2 major complications with a 92% success rate. For the screw group, the mean change was 1.8 cms over 2.2 yrs with 2 minor and 2 major complications giving a success rate of 85%. With staples the success rate was 100% and the mean change was 1.8 cms at an average of 2.3 yrs. In 14 cases where bone age reports were available, the multiplier method seemed better at predicting estimated LLD at skeletal maturity and timing of epiphysiodesis than the Moseley chart.

Conclusions: Percutaneous epiphysiodesis by any method is reliable, minimally invasive and with acceptable complication rate when compared to a corrective osteotomy or open Phemister-type epiphysiodesis. Our experience suggests that the Canale method has the least complications and best success rate. Paleys multiplier method was better at predicting LLD and timing of epiphysiodesis than the Moseley Chart.

Aim: To review our experience with hemi-epiphysiodesis using different methods for the correction of angular deformity about the knee.

Method: This was a retrospective review of 73 patients (101 knees) who underwent hemi-epiphysiodesis from 1999 to 2008. Assessment looked at the type and degree of deformity, implants used, average operating time and hospital stay, complications, degree of correction and the average time to correction.

Results: There were 50 boys and 23 girls with bilateral deformity in 28 cases. There were 88 valgus and 13 varus knees. Average follow-up was 17 months. Staples were used in 28 cases, “8” Plates in 24, Screws in 16 and Drilling in 5 cases. The distal femoral physis was involved in 46 knees, the proximal tibial physis in 21 and both physes in 34 knees (total 135 physes). Average operation time and hospital stay were similar for all methods. There were 6 minor and 3 major complications with staples with an average correction time of 14 months, 3 minor complications with an average correction time of 11 months with “8” plates, 3 minor and 1 major complication with an average correction time of 14 months with screws and 1 minor complication with drilling with an average correction time of 13 months. The outcome was considered as resolved in 47 and pending in 26 cases, with all showing progressive correction of deformity.

Conclusions: Hemi-epiphysiodesis by any method is an effective way to correct angular deformities about the knee in skeletally immature individuals within a reasonable time limit and with minimal morbidity when compared to a corrective osteotomy. Our experience suggests that “8” plates achieve faster correction with the least complications when compared to other methods. Valgus knee deformities corrected faster than varus ones.
