The purpose of this study was to examine the complications and outcomes of total hip replacement (THR) in super-obese patients (body mass index (BMI) > 50 kg/m2) compared with class I obese (BMI 30 to 34.9 kg/m2) and normal-weight patients (BMI 18.5 to 24.9 kg/m2), as defined by the World Health Organization.

A total of 39 THRs were performed in 30 super-obese patients with a mean age of 53 years (31 to 72), who were followed for a mean of 4.2 years (2.0 to 11.7). This group was matched with two cohorts of normal-weight and class I obese patients, each comprising 39 THRs in 39 patients. Statistical analysis was performed to determine differences among these groups with respect to complications and satisfaction based on the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, the Harris hip score (HHS) and the Short-Form (SF)-12 questionnaire.

Super-obese patients experienced significantly longer hospital stays and higher rates of major complications and readmissions than normal-weight and class I obese patients. Although super-obese patients demonstrated reduced pre-operative and post-operative satisfaction scores, there was no significant difference in improvement, or change in the score, with respect to HHS or the WOMAC osteoarthritis index.

Super-obese patients obtain similar satisfaction outcomes as class I obese and normal-weight patients with respect to improvement in their scores. However, they experience a significant increase in length of hospital stay and major complication and readmission rates.

We randomised 250 patients undergoing unilateral, elective hip arthroplasty for osteoarthritis to receive either a cemented or a non-cemented Mallory Head prosthesis. Aspirin was used as prophylaxis against thromboembolism during the first half of the study and adjusted-dose warfarin during the second half. Postoperatively, all patients were asked to have bilateral venography and 80% agreed. All were evaluated clinically for pulmonary embolism.

There was no difference in the frequency of deep-venous thrombosis between the two groups (50% cemented v 47% non-cemented, p = 0.73; 95% CI of the difference −13.6% to 19.3%). Three of the 64 patients (5%) in whom venography had demonstrated isolated distal thrombi developed pulmonary emboli.

A retrospective review of 148 consecutive porous-coated hip arthroplasties (PCA) showed an incidence of thigh pain of 13% one year after surgery, and 22% at two years. Positive correlations were made with femoral stem subsidence (greater than 2 mm) and with distal periosteal and endosteal bone formation. No positive correlations were made with parameters of bone quality or component fit. Resolution of pain occurred in one-third and an anti-inflammatory agent produced partial relief in two-thirds of the patients. We conclude that thigh pain is secondary to stem instability with distal stress transfer in the absence of stable proximal fixation.

The results of 62 ankle arthrodeses, mostly performed for osteoarthritis, have been reviewed; of these, 39 were examined clinically and radiographically after an average follow-up period of seven years. Compression arthrodesis was associated with the highest incidence of complications, and an anterior sliding graft gave the most satisfactory results. Very few patients required modification of their footwear; most could walk independently with a slight limp and were able to return to their pre-operative work. However, after operation, the ability to run and to participate in vigorous sporting activities was limited. Complications included wound infection, non-union, and some change in midtarsal mobility, but excellent pain relief was reported by all patients.

Thirty-three Girdlestone's arthroplasties used to salvage infected total hip replacements were followed for a mean of 6.2 years to assess the efficacy of this procedure. Subjective and objective assessment was obtained at the time of review. Gram-negative organisms, retained cement, bony sequestra and secondary healing were common features of the five patients (15%) whose wounds discharged for more than four weeks after operation. Girdlestone's arthroplasty provided satisfactory pain relief in 91% of patients, and control of infection in 97%. Although leg-length discrepancy (mean 4 cm) and a Trendelenburg gait made walking difficult and tiring , 42% were satisfied with their functional ability; 85% needed walking aids, and 3 patients could not walk at all and were confined to bed or a chair. Overall, 79% were satisfied. Objectively, the mean Harris hip rating was 60; however, if patients with multiple joint problems were excluded, this score increased to 77. Girdlestone's arthroplasty seems a reasonable salvage procedure in the management of an infected total hip replacement and the results seem to improve with time.
