In arthritis of the varus knee, a high tibial osteotomy (HTO) redistributes load from the diseased medial compartment to the unaffected lateral compartment.

We report the outcome of 36 patients (33 men and three women) with 42 varus, arthritic knees who underwent HTO and dynamic correction using a Garches external fixator until they felt that normal alignment had been restored. The mean age of the patients was 54.11 years (34 to 68). Normal alignment was achieved at a mean 5.5 weeks (3 to 10) post-operatively. Radiographs, gait analysis and visual analogue scores for pain were measured pre- and post-operatively, at one year and at medium-term follow-up (mean six years; 2 to 10). Failure was defined as conversion to knee arthroplasty.

Pre-operative gait analysis divided the 42 knees into two equal groups with high (17 patients) or low (19 patients) adductor moments. After correction, a statistically significant (p < 0.001, t-test,) change in adductor moment was achieved and maintained in both groups, with a rate of failure of three knees (7.1%), and 89% (95% confidence interval (CI) 84.9 to 94.7) survivorship at medium-term follow-up.

At final follow-up, after a mean of 15.9 years (12 to 20), there was a survivorship of 59% (95% CI 59.6 to 68.9) irrespective of adductor moment group, with a mean time to conversion to knee arthroplasty of 9.5 years (3 to 18; 95% confidence interval ± 2.5).

HTO remains a useful option in the medium-term for the treatment of medial compartment osteoarthritis of the knee but does not last in the long-term.

We performed a prospective, randomised trial to evaluate the outcome after surgery of displaced, unstable fractures of the distal radius. A total of 280 consecutive patients were enrolled in a prospective database and 88 identified who met the inclusion criteria for surgery. They were randomised to receive either bridging external fixation with supplementary Kirschner-wire fixation or volar-locked plating with screws. Both groups were similar in terms of age, gender, hand dominance, fracture pattern, socio-economic status and medical co-morbidities.

Although the patients treated by volar plating had a statistically significant early improvement in the range of movement of the wrist, this advantage diminished with time and in absolute terms the difference in range of movement was clinically unimportant. Radiologically, there were no clinically significant differences in the reductions, although more patients with AO/OTA (Orthopaedic Trauma Association) type C fractures were allocated to the external fixation group. The function at one year was similar in the two groups.

No clear advantage could be demonstrated with either treatment but fewer re-operations were required in the external fixation group.

Residual pain after total hip due to a number of causes both local to and replacement may be distant from the hip. We describe pain related to the psoas muscle after total hip replacement in nine patients. All presented with characteristic symptoms. We describe the key features and management. Gratifying results were achieved with treatment. This diagnosis should be considered when assessing patients with pain after total hip replacement.

We compared the mechanical properties of carbon fibre composite bone plates with those of stainless steel and titanium. The composite plates have less stiffness with good fatigue properties. Tissue culture and small animal implantation confirmed the biocompatibility of the material. We also present a preliminary report on the use of the carbon fibre composite plates in 40 forearm fractures. All fractures united, 67% of them showing radiological remodelling within six months. There were no refractures or mechanical failures, but five fractures showed an unexpected reaction; this is discussed.

Shelf operations performed on 24 patients (27 hips) for late presentation of congenital hip dysplasia were evaluated. The mean age at operation was 14 years 9 months and the mean follow-up 16 years 8 months. Two-thirds of the hips had good clinical results at follow-up. Patients operated on under the age of 20 years and with little or no radiological evidence of degenerative joint changes had the highest likelihood of success. The shelf operation was found to provide good cover of the femoral head and, should failure occur, also provides adequate superior support for the seating of an acetabular prosthesis.

Three patients referred for rehabilitation of brachial plexus lesions and two referred with leg weakness associated with sciatica were found to have conversion paralysis. The diagnosis was made by demonstrating normal motor nerve conduction to the clinically weak muscles. The weakness was treated by intensive physical rehabilitation with complete and sustained recovery in all cases.
