Purpose: To assess the long-term outcome of Schanz subtrochanteric abduction osteotomy (SO) in patients with long-standing dislocation of the hip

Patients and methods: Between 1962–1981, 11 patients were treated with a SO. Nine patients, in whom 16 SO procedures were performed, were available for follow-up. Seven hips had had failed surgery in infancy, 9 hips had not been operated on previously. The average age at the time of SO was 17.8 (12–29) years. The degree of dislocation at the time of SO was classified according to Eftekhar type B: subluxation; (4 hips); type C: dislocation with neo-acetabulum, (8 hips) patients, and type D: high dislocation, no neo-acetabulum (4 hips). The indications to perform SO were fatigue and a painful lurch in 14 hips and a flexion/adduction contracture with pain in 2 hips. Post-operatively, patients were immobilised in suspended traction for 6–8 weeks, followed by progressive weight-bearing. Follow-up averaged 21 (14–37) years. Follow-up included the Harris-Hip score and ADL-score (Barthel-index); working status, sexual problems, ROM, hip/knee instability and radiographic examination.

Results: Ten secondary surgical procedures were performed at an interval of 6–19 years following SO: shelf procedure ( 5); Epiphyseodesis (3) and total hip (2). The shelf procedures were performed for residual hip pain, at an average of 12 years. The total hips were performed after 17 and 19 years following SO. Both have failed and had complicated hip-revisions. ROM was severely restricted in 4 patients. The mean Harris hips score was 76 ( 27–97). One of six bilateral cases and 2 of 4 unilateral cases had poor functional results. All patients had unlimited ADL activities; 7 patients regularly participated in cycling and swimming. Three female patients experienced minor sexual problems, due to limited abduction. Four patients had 400 excessive valgus at the knee, without clinical or radiographic symptoms. Leg-length discrepancy varied from 0–3 cm.

Conclusion: 1. The results of SO in patients with Eftekhar C/D were surprisingly fair, and poor in type B, subluxation.

We retrospectively reviewed 20 patients at three to 19 years after displaced anterior fracture-dislocations of the hip. Eighteen of them were treated by traction, after ensuring that the femoral head was adequately reduced beneath the undisrupted part of the weight-bearing dome. Two required operation. Although none of the 18 conservatively treated fractures was reduced anatomically, the results were good in ten patients and excellent in the seven in whom the fracture did not involve the weight-bearing dome. We conclude that anterior column fractures have a favourable prognosis after conservative treatment.

We report a retrospective study of 54 acetabular fractures treated by open reduction and internal fixation, with an average follow-up of 9.6 years (3 to 17). Reduction leaving displacement of less than or equal to 2 mm was achieved in 36 hips (67%); good or excellent functional results were obtained in 33 patients (61%). Early complications requiring re-operation included postoperative loss of reduction in one case and an intra-articular screw in another. Arthrodesis or total hip arthroplasty had been performed in 10 patients (19%) who had late symptomatic degenerative changes. Failure to obtain accurate reduction was the most important factor leading to a poor result, but heterotopic calcification caused poor results in seven patients, five of whom had had an anatomical reduction.

A retrospective study of 23 acetabular fractures in patients up to 17 years of age is presented, with an average follow-up of eight years. Good or excellent functional results were achieved in 21 patients; radiographic results were good or excellent in 16. Conservative treatment gave consistently good results in fractures with minimal initial displacement, stable posterior fracture-dislocations and Salter-Harris type 1 and 2 triradiate cartilage fractures. Less favourable results were seen in type 5 triradiate cartilage fractures and in comminuted fractures, but operation was no better. Unstable posterior fracture-dislocations and irreducible central fracture-dislocations need operative treatment but the results may still be unsatisfactory.

Four patients with injuries of the acetabular triradiate cartilage are presented. In three of them premature fusion of the cartilage occurred; two of these developed acetabular deformity and subluxation of the hip. In all patients the sacroiliac joint also was injured; in two, the joint was completely disrupted, leading to fusion and growth disturbance of the ilium. As injury of the triradiate cartilage is easily missed on the initial radiograph, it is advised that all patients with pelvic trauma should be followed clinically and radiographically for at least one year.
