The relationship between hindfoot deformity and forefoot pressure was assessed in 28 rheumatoid patients who had undergone forefoot reconstruction four years previously. Patients with valgus hindfoot deformities tended to have high forefoot pressures whereas those with a normal hindfoot recorded normal pressures on the dynamic pedobarograph. All patients with residual forefoot pain recorded abnormal forefoot pressures. We believe that orthotic control of hindfoot deformities should be considered for those patients who require forefoot surgery as a combination of surgical and orthotic management may offer the best chance of success.

We report the results of a prospective study of the incidence of algodystrophy following Colles' fracture in 60 patients, using sensitive or quantitative techniques for the assessment of each feature of the syndrome. Nine weeks after fracture, 24 patients had evidence of vasomotor instability, 23 had significant tenderness of the fingers and 23 had lost finger movement. These three abnormalities were significantly associated (p less than 0.001). Swelling was also significantly associated with these three variables. There was no statistical association between the occurrence of algodystrophy and the patient's age or sex, the severity of the fracture, the number of reductions performed or the adequacy of the reduction. We conclude that algodystrophy constitutes a precisely definable and quantifiable syndrome which is more common than has been suspected.

A series of 42 ankle fractures have been randomised into two groups respectively undergoing either open reduction and internal fixation or manipulative reduction and plaster. Their progress after removal of all external splintage has been followed using simple gait analysis techniques. There appears to be no difference in the outcome of treatment of the two groups in the early recovery period (up to 20 weeks).

We report a prospective study of the causes and treatment of 26 long-standing neuropathic ulcers of the foot in 21 patients. The most important causal factor, well illustrated by pressure studies, was the presence of a dynamic or static deformity leading to local areas of peak pressure on insensitive skin. All but one of the 26 ulcers had healed after an average of 10 weeks of treatment in a light, skin-tight plaster cast, with the prohibition of weight-bearing. Recurrent ulceration was prevented in all but one foot by early operation to correct the causative deformity; this was performed after the ulcer had healed and before allowing weight-bearing on the limb. Pressure studies after operation confirmed that pressure points had been relieved.

Static and dynamic measurements of foot pressure have been carried out on three groups of subjects: diabetic patients with neuropathy (with and without a history of ulceration), diabetic patients with no neuropathy, and normal subjects as controls. In many cases both techniques of measurement detected areas of abnormally high pressure under the foot, but in some cases a particularly high-pressure spot was detected on only one of the tests and sometimes both methods were needed to reveal all the areas of the foot which might be considered to be at risk. The dynamic measurements tended to show multiple areas of high pressure better than the static measurements. Our results indicate the importance of making both types of measurement when seeking to devise suitable means of protecting the foot from ulceration.

The medical treatment of eight patients with paraparesis associated with Paget's disease of the vertebrae is described. Treatment, for 3 to 87 months, with calcitonin or with diphosphonates produced marked clinical improvement in seven of these patients. From this series and a review of 19 additional case reports it is concluded that favourable clinical response is seen in about 90 per cent of patients, and that this may occur very rapidly. Results are as good or better than those obtained by surgical decompression. It seems possible that paraparesis in some cases may be due to diversion of blood supply from the spinal cord to the highly vascular Pagetic bone giving rise to a vascular "steal" syndrome. It is suggested that medical treatment should be used more widely to avoid or delay the need for operation and reduce the risks of recurrence. These patients, however treated, require lifelong follow-up because relapses are common.

Forty-nine patients treated by epiphysial stapling for idiopathic genu valgum are reviewed. The children were aged from eleven to fourteen and a half years. The severity of the condition and subsequent correction were assessed by measuring the inter-malleolar distance. Results show that femoral stapling is the treatment of choice for most patients with inter-malleolar separation of up to 12-5 centimetres. The optimum age for stapling for both boys and girls is eleven and a half years. Stapling of both epiphyses is advised for those patients presenting late, for example, between thirteen and fourteen and a half years, or where the deformity is greater than 12-5 centimetres of separation. Correction rarely takes more than one year, and was cosmetically satisfactory in all cases. The operation is virtually free from complication except for a tendency for the scars to be broad and conspicuous. Stapling has proved to be a safe, effective and predicatable operation for idiopathic genu valgum.

1. Nineteen patients with spina bifida, myelomeningocele or lipoma of the cauda equina have been reviewed. Convex pes valgus was found in twenty-five feet. All patients had a neuromuscular imbalance between the evertors and invertors of the foot.

2. Results of release procedures only and of those which combine release procedures with tendon transfers are compared; they show that there is no consistently satisfactory operation for correction of the deformity when it exists with neuromuscular imbalance.

3. An operation in which release procedures are combined with the transfer of the peroneus brevis to the tibialis posterior and of the tibialis anterior to the neck of the talus is described. It has given satisfactory results in two out of three patients with paralytic convex pes valgus.
