Management of equinus contractures of the ankle in haemophilia.

Equinus deformity has been a significant problem in haemophilia. It causes difficulties in walking and secondary problems in adjacent joints. There are a number of potential causes in haemophilia. A careful history, examination, and plain radiographs will determine the aetiology, which frequently is multifactorial. Hopefully, prophylactic factor replacement will reduce the incidence of such problems in the future. Prompt 'on demand' therapy will reduce the complications of articular and soft-tissue bleeds. Physiotherapy, splints, and orthotics will usually allow a full recovery of function and comfort. Rarely, surgical intervention is required to correct articular and/or musculo-tendinous problems. The choice of surgery depends upon the cause(s) of the deformity and should only be undertaken in experienced haemophilia units following careful counselling of the patient regarding the aims and nature of the operation and the patient's involvement in an effective rehabilitation programme.
