Question

Quizplus · Accepted Answer

Claw toe is a deformity in which the interosseous muscles and/or lumbrical muscles progressively contract, causing the toes to curl downward and the joints to become rigid. Hammer toe involves the same type of contracture, but specifically affects the proximal interphalangeal joint, whereas claw toe affects both the proximal and distal interphalangeal joints. Morton's toe and hallux valgus involve different types of deformities, and do not involve progressive contracture of the interosseous or lumbrical muscles.
