title: Use of a Kirschner wire for distraction and capsular flaps in the Keller interpositional arthroplasty.
abstract: We describe a simplified capsular interpositional technique for the Keller bunionectomy that uses a Kirschner wire to interpose the capsule into the first metatarsophalangeal joint without requiring sutures. The capsule acts as a biologic spacer in the first metatarsophalangeal joint, allowing for fibrosis to fill the void created, with the Kirschner wire maintaining the distance between the metatarsal head and the stump of the proximal phalanx. This creation of a nonpainful pseudarthrosis prevents shortening of the hallux and retraction of the base of the proximal phalanx on the metatarsal head.
