RESUMO
Problems with the gastrocnemius-soleus muscle group can severely impair the gait of children with cerebral palsy. Treatments, including bracing, muscle lengthening, neurectomy, or a combination, have been used with mixed results. Soleus neurectomy was performed as the primary treatment for ankle clonus in 38 legs of 21 children with a variety of cerebral palsies. Concurrent heel cord or muscle lengthening was performed if needed. Patients were followed for an average of 9 years (range, 2 to 14 years). Clonus recurred in 4 treated ankles. In 2 cases, this was due to a nerve anomaly. Postneurectomy Achilles tendon lengthening was required in 8 of the treated ankles. Neurectomy was beneficial for 19 of 21 children. Functional improvements included better control of stopping, better balance, and less toe walking. The greatest improvement was seen in those patients who did not also have heel cord contractures.
