Histochemical investigation was made on the muscle in patient with deformed foot resulting from other than congenital club foot.
Samples of muscle were obtained from 34 patients; flaccid paralysis (10), spastic paralysis (7), arthrogryposis multiplex congenita (4), club foot deformity due to anomaly (8), and others (6).
The site of muscle biopsy was gastrocnemius (13), abductor hallucis (10), extensor digitorum brevis (10), and others (17).
In flaccid paralysis, most of specimens show fiber type grouping. In spastic paralysis, there were no tendency of specific pattern. In clubfoot deformity due to anomaly, a half of specimens show either type I or type II fiber type hypotrophy. In patients over 5 years of age, extensor digitorum brevis show fiber type grouping, inspite of it's disorders.
