MacIntosh-Jones reconstruction for the unstable knee.

A group of 45 patients who underwent replacement of a ruptured anterior cruciate ligament with a free graft of one-third of the patellar tendon combined with a lateral extra-articular tenodesis have been reviewed. The average age of the patients was 26.4 years and the mean follow-up period 3.2 years. Stability was achieved in 42 patients (93 per cent), judged on clinical criteria. Overall patient satisfaction was high at 73 per cent and 38 patients (84 per cent) maintained their sporting activity at a social or competitive level. Those who had unsatisfactory results had undergone significant delay before anterior cruciate ligament reconstruction.

Total knee replacement in patients with Parkinson's disease.

Total knee replacements were performed on three patients with Parkinson's disease. The rehabilitation of all three was, however, hampered by inhibition of the extensor mechanism, hamstring rigidity and poor muscular co-ordination. Medical treatment of the disease did not help. None of the patients became mobile, and all three gradually weakened and died. We suggest that, at least in some patients with Parkinson's disease, knee replacement is contra-indicated.

A population study of Dupuytren's contracture.

Nine hundred and nineteen patients attending orthopaedic clinics in the rural areas of the Cotswolds and Chilterns were examined for evidence of Dupuytren's contracture. Five per cent of men and 3.5 per cent of women showed evidence of the disease which was largely bilateral but confined to the palm in forty per cent of men and eighty per cent of women. A positive correlation between repeated stretching of the palmar fascia and the presence of Dupuytren's contracture confined to the palm was established.

Suggested method for closed treatment of fractures of the carpal scaphoid: hypothesis supported by dissection and clinical practice.

The anatomy and kinetics of the carpus with special reference to the fractured scaphoid are described. Clinical, radiological and post-mortem studies of the wrist show that the scaphoid can be immobilized and compressed in its long axis, with the wrist held in full supination, mid-dorsiflexion and full ulnar deviation. Immobilization of the upper limb in this position for four weeks has achieved union of those fractures of the scaphoid which are often problematical, i.e. the displaced fracture, fractures of the proximal pole, and those exhibiting delay in union of many months. The method of manipulation and immobilization in a plaster of Paris cast is described, and some clinical examples are presented. The indications for the complications of the method of treatment are discussed and briefly compared with other methods of treatment.
