Purpose of the study: Resection of the lateral quarter of the clavicle is an effective treatment for painful acromio-clavicular arthropathy. An open procedure can create a disgraceful or painful scar or be associated with secondary instability and muscle weakness. Arthroscopic resection would avoid these complications.

Material and methods: Between 1992 and 2002, 35 patients were treated arthroscopically for isolated painful acromioclavicular arthropathy after failure of medical treatment. Twenty-seven patients (mean age 44 years) were reviewed clinically (Constant score, subjective outcome, stability) and radiographically (quality of resection, coraco-clavicular space, ossification) at more than two years follow-up. Acromioplasty was performed in all cases to improve exposure in 14 or because of an aggressive acromion (n=7). A scarf orthesis was worn to prevent pain. Self-controlled rehabilitation exercises were proposed.

Results: There were no postoperative complications excepting one case of retractile capsulitis in the context of an occupational accident. Excluding this case, mean sick-leave was five weeks (range 3–20). At mean follow-up of seven years, all scars were pain free and minimally visible. There was no problem with frontal or sagittal instability. The Constant score improved 24 points on average compared with the preoperative score with a significant gain for pain (+9 points). Two patients were disappointed: one retained a sequellar capsulitis and one persistent pain after insufficient resection. On average, the resection measured 10 mm (range 6–20 mm). Three patients had an insufficient posterosuperior resection. The coracoclavicular interval remained unchanged in all cases and four patients presented secondary ossification of the resection zone. Two patients were sensitive to acromioclavicular palpation with a positive cross arm test (one had an insufficient resection and the other ossifications at last follow-up).

Discussion and conclusion: Arthroscopic acromio-clavicular resection reduced operative morbidity. The operation does not destabilize the joint. The total joint surface area can be resected to avoid a residual pos-terosuperior impingement which would be a source of persistent pain. The presence of secondary ossifications in the zone of resection has led us to propose NSAID treatment although the prophylactic effect remains to be demonstrated.

Purpose: In 1988, the conclusions of the SOFCOT symposium appear to condemn use of cemented implants for revision of loosened femoral elements. Eleven years later, at the 1999 Symposium, Vidalain demonstrated that cementing remains a reasonable alternative. The purpose of this retrospective analysis was to estimate long-term results of revisions using a long cemented stem without bone stock reconstruction.

Material and methods: From 1987 to 1995, 135 patients (135 hips) underwent revision surgery with this technique. We retained for analysis 95 hips (15 lost to follow-up 25 deceased patients) in 66 women and 29 men, mean age 70 years at revision (42–86). The preoperative Postel Merle d’Aubigné (PMA) function score was 8/18. Femoral implants in place had been cemented in 80% of the hips. Using the SOFCOT criteria, 65% of the loosenings were stage II, 29.5% stage III. All were aseptic loosenings and the same revision technique was used in all cases: removal-replacement of both prosthetic elements, use of a long cemented stem without associated grafting.

Results: Mean follow-up was eight years (60–157). Thirty nine percent of the patients had early postoperative complications. The mean function score at last follow-up was 14.8/18 with 62.4% of the outcomes considered good or very good. Age, restitution of the rotation centre, quality of cementing, and stem/femur fit influenced the result significantly. Radiographic analysis showed a progressive lucent line in 32% of the hips, only 36% of the femoral stems were totally free of lucent lines. Cumulative actuarial survival was 87% at 14 years and fell to 65.5% considering certain radiographic loosening as the endpoint.

Conclusion: Use of a long cemented femoral stem for revision total hip arthroplasty provides acceptable long-term functional outcome. Results are significantly affected by imperfect technique. This type of implant, which destroys any hop for restoration of bone stock, should be reserved of elderly subject where a more “ambitious” procedure were be too risky.

Purpose: Acetabular reconstruction is particularly challenging in case of acetabular loosening with important loss of bone stock. The purpose of this retrospective study was to estimate long-term results after revision procedures using a fragmented allograft and a supporting ring.

Material and methods: From 1987 to 1995, 135 patients (135 hips) underwent this procedure. Ninety-five files were reviewed (15 patients were lost to follow-up and 25 died). The 95 patients retained for analysis were 66 women and 29 men, mean age at surgery 70 years (range 42–86). The preoperative functional score (PMA) was 8/18. The acetabular implants in situ had been cemented in 62% of the cases and non-cemented in 38%. According to the SOFCOT criteria, 79% of the loosenings were associated with grade 3 bony lesions, 15.8% with grade 4 lesions and 5.2% with grade 2 lesions. In all cases, the acetabulum was reconstructed with fragments of allografts. An Eichler ring was used in 56% of the cases, a Ganz ring in 25%, and a Muller ring in 19%.

Results: Mean follow-up was eight years (60–157 months); 39% of the patients developed early postoperative complications including one dislocation and two haematomas. Mean functional score at last follow-up was 14.8/18 with 64% good or excellent results. Reconstruction of the centre of rotation was the only factor significantly affecting results. Radiographically, 85% of the cups presented no sign of loosening at last follow-up. The grafts were considered to be assimilated or unchanged in 81% of the cases, with partial or total lysis in 19%. Actuarial analysis of cumulative survival, considering surgical revision or clinical and radiographic loosening as the endpoint was 87% at 14 years.

Discussion: Fragmented allografts can be perfectly stabilised with a supporting ring to reconstitute bony stock of the acetabulum. Long-term clinical and radiographic results are encouraging.

Purpose: Posterior instability of the shoulder requires surgical treatment in involuntary forms and after failure of functional treatment. As for anterior instability, a bone block can be fashioned from an iliac graft or a pediculated graft harvested from the acromion. This retrospective analysis concerned the results obtained in eighteen consecutive cases.

Material and methods: This series included ten men and eight women, mean age 26 years (15–42) at time of surgery. Fourteen (77%) practised sports activities including four at competition level. Symptoms had persisted for four years on the average. For three patients (16%) posterior instability was expressed by recurrent luxation subluxation. For nine patients (50%) posterior subluxation was a common involuntary event. Six patients suffered from painful shoulders due to an unrecognised posterior instability accident. Diagnosis of posterior instability was establised by arthroscopy in seven patients (39%). For nine shoulders the intervention consisted in a screwed posterior iliac block associated with a tension procedure on the capsule (group 1). For the other nine shoulders the block was harvested from the acromion and pediculated on the deltoid (group 2).

Results: Mean follow-up for all patients was eight years. The Duplay score was 75 points at last follow-up. Twelve patients (85% of the athletes) were able to resume their sports activities, half at the same level. Nine patients were pain free. Six patients (33%) had persistent apprehension but did not present true recurrence at physical examination. The Duplay score was 69.4 points in group 1 (follow-up 12 years) and 82.2 points in group 2 (follow-up three years). Thirteen patients (77%) did not have any sign of joint degeneration at last follow-up. One patient had advanced stage IV degeneration related to an intra-articular screw. All patients felt their shoulder had been improved by surgery and one third were disappointed with the results.

Discussion: Use of a posterior block is an effective treatent for posterior instability giving results comparable with those obtained with anterior blocks in terms of shoulder stability, pain, recovery of motion, and subjective outcome. This procedure favours joint degeneration less than anterior stabilisation. Results obtained with pediculated acromial blocks are encouraging.
