Total hip replacement after intertrochanteric osteotomy.

Forty-five hips were analyzed in 42 patients treated with total hip replacements (THR) after earlier intertrochanteric osteotomies. At time of osteotomy, the patients' mean age was 50 years (range: 14 to 65). Total hip replacement was performed at a mean interval of 11.9 years later (standard deviation: 7.7). Narrowing or closure of the medullary canal made insertion of the prosthesis stem difficult in 10 cases. After THR, the patients were followed for a mean of 6 years (range: 3 to 11). At follow up, the hips had a mean Mayo score of 81 (SD = 13) points (17 excellent, 12 good, 7 fair, 9 poor). The failure rate was 6.7%. Being overweight had an adverse effect on outcome. Intertrochanteric osteotomy may impair results after subsequent THR.

A comparison between cemented and cementless implants in revision arthroplasty of the hip following resection arthroplasty.

Twenty patients underwent hip re-arthroplasty following resection arthroplasty due to former prosthetic infection, aseptic loosening, or TBC coxitis. In 9 cases Gentamycin-loaded cement was used. In 11 the re-arthroplasty was cementless. The overall results, evaluated by the Mayo and Harris scoring systems, were moderately good. Seventy-five per cent of patients reported relief from pain and improved hip function. However, in the previously infected cases significantly better results were found in the cementless group, while major complications such as deep infection, luxation, or loosening of the implant were mainly concentrated in the cementless re-arthroplasties following aseptic loosening and cemented re-arthroplasties following septic as well as aseptic failures.

Total hip replacement after failed hemiarthroplasty.

A retrospective follow-up study comprising 37 patients operated upon using total hip replacement (THR) following failed hemiarthroplasty (HA) is reported. The mean duration time after HA was 83 months. Twenty-four patients showed satisfactory results at a mean follow-up of 4.8 years, while 13 patients found the results unsatisfying from the very beginning. The mean (SD) observation time after THR was 50 (38) months. The mean (SD) age of 28 women and 9 men examined at the follow-up was 69 (10) years. The mean Mayo/Harris hip scores were 76/76 (range 41-98) points. The final results were excellent in nine, good in ten, fair in five and poor in thirteen cases. After complicated subcapital femoral fractures treated by HA, the final result after THR was excellent or good in four, fair in three and poor in seven cases. However, revision arthroplasty was performed in two cases, in the one because of loosening, in the other due to recurrent dislocation. Radiologically, at follow-up in 13 patients, 11 femoral and 6 acetabular components showed signs of loosening. In conclusion, THR can be recommended as primary operation for the treatment of acute subcapital femoral fractures in elderly and active patients.

Non-work-related movements in machine-paced and self-paced work: an industrial study.

Non-work related movements (NWRM) of 10 experienced industrial workers performing light repetitive work were observed under a variety of conditions. More NWRM were observed for (1) machine-paced versus self-paced operations; and (2) a task with high mental load versus one with a low mental load. In addition, the age of the worker was found to be negatively correlated with NWRM.
