The importance of gastrocnemius recession in the correction of equinus deformity in cerebral palsy.
Spasm or contracture of the gastrocnemius muscle is predominantly responsible for the equinus deformity of the foot in cerebral palsy. Its release is therefore logical in the treatment of all cases which do not respond to conservative measures. The authors have demonstrated, by the use of metal markers and radiographic control at operation, that adequate release cannot be achieved by severance of the calcaneal tendon alone, and that in order to ensure relaxation of the gastrocnemius muscle, the operation of choice is gastrocnemius recession by the method of Strayer, coupled with lengthening of the calcaneal tendon to deal with such degree of the deformity as may be attributable to shortening of the soleus. A survey of 100 limbs treated by this method revealed a recurrence rate of equinus of 9% and a degree of calcaneus deformity resulting in inadequate push-off in 3% of cases after an average follow-up period of six years.
