We performed 83 consecutive cemented revision total hip arthroplasties in 77 patients between 1977 and 1983 using improved cementing techniques. One patient (two hips) was lost to follow-up. The remaining 76 patients (81 hips) had an average age at revision of 63.7 years (23 to 89).

At the final follow-up 18 hips (22%) had had a reoperation, two (2.5%) for sepsis, three (4%) for dislocation and 13 (16%) for aseptic loosening. The incidence of rerevision for aseptic femoral loosening was 5.4% and for aseptic acetabular loosening 16%. These results confirm that cemented femoral revision is a durable option in revision hip surgery when improved cementing techniques are used, but that cemented acetabular revision is unsatisfactory.

We have reviewed 30 patients who had been treated conservatively for acromioclavicular dislocation between 1979 and 1982 at an average of 12.5 years after the injury. All except one had a good outcome as did five others contacted by telephone. In all patients reviewed the acromioclavicular joint remained subluxed or dislocated.

With conservative treatment a good long-term outcome can be expected without restoration of the anatomical configuration of the joint.

1. One hundred cases of arthrodesis of first metatarso-phalangeal joint have been reviewed after a post-operative interval of at least ten years.

2. Seventy-seven per cent of patients were completely satisfied with the late results ; only 9 per cent were dissatisfied.

3. The two major factors leading to poor results were found to be malposition of the arthrodesis, and interphalangeal osteoarthritis.

4. The ideal position for fusion is considered to be in at least 20 degrees of valgus, preferably between 20 and 30 degrees ; between 20 and 40 degrees of dorsiflexion ; and most importantly, neutral rotation.

5. The precise operative technique is not important provided it maintains the position obtained at operation until the arthrodesis is sound.

1. The results have been reported of total hip replacement by a low-friction technique using high-density polyethylene for the acetabular component in 379 primary interventions, performed between November 1962 and December 1965 and followed for between four and seven years.

2. Apart from failures due to infection, the rate of which in the era under review was 3·8 per cent, late failures from mechanical causes were unusual after total hip replacement by this technique. When the socket was cemented in position, which is now routine, the late mechanical failure from all causes was only 1·3 per cent in 210 cases.

3. As regards the quality of the results and their maintenance over the years, the results were so good (Table X) that it was unnecessary to distinguish an intermediate class of "improvement" between success and failure.

4. As regards relief of pain and ability to walk, the average final rating, on a scale numbered 1 to 6, was 5·9 for both, indicating 90 per cent of patients in Grade 6 (excellent) and only 10 per cent in Grade 5 (good).

5. The average recovery of movement was not as spectacular and was influenced considerably by the pre-operative range, but in all cases that range was improved on. Even starting with the stiffest of hips about one patient in four regained a right angle of flexion movement. There was no tendency to lose movement with the passage of time.

6. As regards late infection (2·2 per cent out of a total of 3·8 per cent), the various findings tend to exonerate cement as a cause.

7. The mechanical details of the technique became stabilised in the period 1959 to 1962 in the Teflon era, and with the exception of improved methods of reattachment of the greater trochanter, they are identical with our current practice in 1971.

We reviewed the long-term results of the treatment of slipped upper femoral epiphysis (SUFE) using realignment procedures in 36 patients (37 hips) at an average follow-up of 33.8 years (26 to 42). There were serious short-term complications in seven of the 22 hips treated by subcapital osteotomy, three of the 11 hips treated by intertrochanteric osteotomy and three of the four hips treated by manipulative reduction.

At re-examination, the clinical and radiological results were excellent or good in 41% of the hips treated by subcapital osteotomy, in 36% treated by intertrochanteric osteotomy and in none treated by manipulative reduction. In all, seven hips (19%) had had arthrodesis or total hip replacement.

The natural history of SUFE was probably not improved by any of the treatments used in our study. We therefore discourage the use of subcapital and intertrochanteric osteotomy as well as manipulative reduction in the primary treatment of chronic SUFE.

Revision after failed femoral components may be technically demanding due to loss of peri-prosthetic bone. This retrospective study evaluated the long-term results of femoral revision using the cementless Wagner Self-Locking stem. Between 1992 and 1998, 68 consecutive hips in 66 patients underwent femoral revision using this implant. A total of 25 patients died from unrelated causes without further revision; the remaining 41 hips in 41 patients (12 men and 29 women) with a mean age of 61 years (29 to 80) were reviewed at a mean follow-up of 13.9 years (10.4 to 15.8). A transfemoral approach was used in 32 hips. A total of five stems required further revision because of infection in two, progressive subsidence in two and recurrent dislocation in one. Four hips had dislocated and eight stems had subsided ≥ 10 mm. The mean Harris hip score improved from 33 points pre-operatively to 75 points at final follow-up (p < 0.001). In all, 33 stems (91.7%) showed radiological signs of stable bone fixation. The cumulative survival rates at 15.8 years with femoral revision for any reason and for stem failure as the endpoints were 92.0% (95% confidence interval (CI) 86.0% to 98.4%) and 96.6% (95% CI 92.2% to 100%), respectively. The survivorship with revision and ≥ 10 mm migration of the stem as the endpoint was 83.6% (95% CI 76.6% to 91.4%).

This study shows quite good survival and moderate clinical outcome when using a monoblock tapered titanium stem for supporting the regeneration of bone in complex revision hip surgery.

Aims. We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect. Methods. During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients. All were reviewed three to four months after injection, and 241 replied to a questionnaire a mean of 36 months (12 to 88) after the last injection. No pain at the early review was considered early success. When the patient had not been subsequently operated on, and indicated on the questionnaire that they were either well or much better, it was considered a long-term success. Results. At the three- to four-month review, 22 (9%) reported that they had no pain. The long-term success of one injection was 15% and rose to 29% after a second injection. Logistic regression tests showed that both early success (odds ratio (OR) 5.5, 95% confidence interval (CI) 2.1 to 14.4; p = 0.001) and late success (OR 3.7, 95% CI 1.7 to 8.3; p = 0.001) was greater with triamcinolone than with betamethasone. Late success was greater for patients with symptoms for less than 12 months (OR 3.0, 95% CI 1.4 to 6.7; p = 0.006). We saw no complications of the injections. Conclusion. We conclude that the effect of corticosteroid injection for coccygodynia is moderate, possibly because we used modest doses of the drugs. Even so, they seem worthwhile as they are easily and quickly performed, and complications are rare. If the choice is between injections of betamethasone or triamcinolone, the latter should be selected. Cite this article: Bone Joint Open 2020;1-11:709–714

We retrospectively reviewed the outcomes of 33 consecutive patients who had undergone an extra-articular, total or partial scapulectomy for a malignant tumour of the shoulder girdle between 1 July 2001 and 30 September 2013. Of these, 26 had tumours which originated in the scapula or the adjacent soft tissue and underwent a classic Tikhoff–Linberg procedure, while seven with tumours arising from the proximal humerus were treated with a modified Tikhoff-Linberg operation. We used a Ligament Advanced Reinforcement System for soft-tissue reconstruction in nine patients, but not in the other 24.

The mean Musculoskeletal Tumor Society score (MSTS) was 17.6 (95% confidence interval (CI) 15.9 to 19.4); 17.6 (95% CI 15.5 to 19.6) after the classic Tikhoff–Linberg procedure and 18.1 (95% CI 13.8 to 22.3) after the modified Tikhoff–Linberg procedure. Patients who had undergone a LARS soft-tissue reconstruction had a mean score of 18.6 (95% (CI) 13.9 to 22.4) compared with 17.2 (95% CI 15.5 to 19.0) for those who did not.

The Tikhoff–Linberg procedure is a useful method for wide resection of a malignant tumour of the shoulder girdle which helps to preserve hand and elbow function. The method of soft-tissue reconstruction has no effect on functional outcome.
