Osteotomy of the hallux proximal phalanx.

Osteotomy of the proximal phalanx appears to be used more frequently and with increasing indications. It rarely is indicated as the only surgical procedure and often is combined with a secondary procedure. In hallux valgus surgery, a proximal or distal metatarsal osteotomy often is used, and in hallux rigidus, a cheilectomy usually is added. The advantage of a proximal phalanx osteotomy is that it enables an extra-articular correction, which avoids breaching the metatarsophalangeal joint. This extra-articular correction may prevent joint stiffness and long-term joint changes.
