A, Moderate hammer toe deformity with fixed contracture at proximal interphalangeal joint but only extensor tightness at metatarsophalangeal joint with no fixed extension contracture. B, Dorsal elliptical incision over proximal interphalangeal joint. C, Superficial dissection leaving dorsal veins visible to make cauterization easier. D, Dorsal capsule, both collateral ligaments, and extensor tendon are sectioned transversely, and toe is acutely flexed. E, Extensor tendon is dissected proximally to junction of middle and distal thirds of proximal phalanx. F, Distal 25% to 30% of proximal phalanx is excised and rests on middle phalanx. Small dorsal incision for extensor tenotomy. G, Closure of wound. SEE TECHNIQUE 84.9.
