We treated eight dysplastic acetabula in six skeletally mature patients with Down’s syndrome by a modified Bernese periacetabular osteotomy. The mean age at the time of surgery was 16.5 years (12.8 to 28.5). Mean length of follow-up was five years (2 to 10.4). Pre-operatively the mean (Tönnis) acetabular angle was 28°, the centre-edge angle was −9°, and the extrusion index was 60%; post-operatively they were 3°, 37°, and 17%, respectively. Two patients with post-operative (Tönnis) acetabular angles > 10° developed subluxation post-operatively and required secondary varus derotation femoral osteotomies. Another patient developed a late labral tear which was treated arthroscopically. All eight hips remain clinically stable, and are either asymptomatic or symptomatically improved. These results suggest that the modified Bernese periacetabular osteotomy can be used successfully in the treatment of acetabular dysplasia in patients with Down’s syndrome

Keywords. Shoulder; dislocation; instability; skeletal immaturity; arthroscopic Bankart repair; outcomes. Introduction. Non-operative management of traumatic shoulder instability in children has a recurrence rate of up to 100%. Short-term outcomes of surgery in adults results has a quoted recurrence rates of around 10%. The aim of this study was to examine the surgical outcomes of adolescent patients (aged 13 to 18 years) undergoing arthroscopic stabilisation for shoulder instability. Methods. All patients had a labral tear sustained whilst participating in contact sports (84% rugby). Atraumatic, primary joint hyperlaxity and dyskinetic causes were excluded. All patients had a primary arthroscopic stabilisation. Patients were reviewed in clinic or contacted by post with a standardised outcome proforma. Sixty one shoulders in 57 patients met the inclusion criteria and were included. Mean follow up was 22 months, mean age was 16.8 (range 13 to 18), and 98% were male. All were Stanmore type 1 pathology. 16% had a concomitant SLAP repair, and 16% had a posterior labral tear. Results. 31% (19) reported recurrent dislocation, and 11 patients required further surgery. This is significantly higher than published series for adults, despite the senior author being a tertiary specialist. Despite the high recurrence rate, the median improvement in shoulder function was 90% and the median VAS for pain was 0. The majority of patients (61%) had a full return to pre-injury sporting activities, while 23% returned to decreased sporting activity and 16% stopped. The mean post-operative Oxford instability score was 26.8 (SD 12.9 range 12 to 48). 90% of recurrent dislocations occurred whilst playing rugby, but other than this, we could not identify any significant risk factors for the 19 shoulders that had recurrent dislocations (gender, type of sport, hyper laxity, type of tear). Conclusions. This study demonstrates that adolescent patients have a high risk of recurrent dislocation following arthroscopic stabilisation. Patients should be appropriately counselled and alternative procedures such as the coracoid transfer should be considered. Level of evidence: IV

Aim. This pilot study aimed to identify the important symptomatic, functional and psychosocial aspects of hip disorders from the perspective of adolescent patients and their families in order to begin developing a patient-focused instrument (Bridging Adolescent Self-Reported Hip – BASH - score). Methods. This was a qualitative patient-centred study at a tertiary paediatric orthopaedic centre involving 50 adolescents aged 13–17 years, composed of five groups of 10 adolescents with slipped capital femoral epiphysis (SCFE), hip dysplasia (DDH), labral tears undergoing arthroscopic treatment, lower limb trauma and a miscellaneous group with conditions including Perthes' disease. A control group of 100 adolescents were also interviewed from a local school. Adolescent and separate concurrent parent groups underwent an ‘open’ phase face-to-face or telephone interview (theme development). This involved agreeing or disagreeing with statements, and open exploration of ideas related to the ‘day in the life’ of an adolescent with hip problems in order to generate and specify themes. This was followed by ranking and finally, scoring and testing. Results. All focus groups consistently and successfully generated themes related to hip problems and the majority of adolescents and parents were able to easily localise their issues to the hip. The ranking activity enabled the final definition of three key themes: a) physical symptoms, b) limitations and restrictions on life activities and situations and c) emotional experiences and self-consciousness which formed the basis of scoring and testing and the test version of the BASH score for adolescents. Scaling was developed with a total of 20 items rated on a five-point scale based on the frequency of effect from 0 (always) to 5 (never) providing a maximum score of 100. Conclusion. The BASH score is the first patient-reported outcome score for adolescent hip disorders developed with adolescents for adolescents

Aims

This study analysed the clinical and radiological outcome of anatomical reduction of a moderate or severe stable slipped capital femoral epiphysis (SCFE) treated by subcapital osteotomy (a modified Dunn osteotomy) through the surgical approach described by Ganz.

We present our experience of the modified Dunn procedure in combination with a Ganz surgical dislocation of the hip to treat patients with severe slipped capital femoral epiphysis (SCFE). The aim was to prospectively investigate whether this technique is safe and reproducible. We assessed the degree of reduction, functional outcome, rate of complications, radiological changes and range of movement in the hip. There were 28 patients with a mean follow-up of 38.6 months (24 to 84). The lateral slip angle was corrected by a mean of 50.9° (95% confidence interval 44.3 to 57.5). The mean modified Harris hip score at the final follow-up was 89.1 (sd 9.0) and the mean Non-Arthritic Hip score was 91.3 (sd 9.0). Two patients had proven pre-existing avascular necrosis and two developed the condition post-operatively. There were no cases of nonunion, implant failure, infection, deep-vein thrombosis or heterotopic ossification. The range of movement at final follow-up was nearly normal. This study adds to the evidence that the technique of surgical dislocation and anatomical reduction is safe and reliable in patients with SCFE.

We evaluated radiological hip remodelling after shelf acetabuloplasty and sought to identify prognostic factors in 25 patients with a mean age of 8.9 years (7.0 to 12.3) who had unilateral Perthes’ disease with reducible subluxation of the hip in the fragmentation stage.

At a mean follow-up of 6.7 years (3.2 to 9.0), satisfactory remodelling was observed in 18 hips (72%). The type of labrum in hip abduction, as determined by intra-operative dynamic arthrography, was found to be a statistically significant prognostic factor (p = 0.012).

Shelf acetabuloplasty as containment surgery seems to be best indicated for hips in which there is not marked collapse of the epiphysis and in which the extruded epiphyseal segment slips easily underneath the labrum on abduction, without imposing undue pressure on the lateral edge of the acetabulum.
