A rare case of peroneal spastic flat foot (P. S. F. F.) associated with accessory scaphoid is reported. The patient is a 12 years old boy. His chief complaint was left foot pain.
On examination, left foot had valgus deformity. No peritalar motion existed due to apparent spasm of the peroneal and extensor digitorum longus tendons.
Roentgenographic and CT examinations revealed no significant findings except for accessory scaphoid. The symptoms were completely relieved by removal of the accessory scaphoid.
