title: The modified oblique Keller procedure: a technique for dorsal approach interposition arthroplasty sparing the flexor tendons.
abstract: A first metatarsophalangeal joint resection arthroplasty that combines a modest metatarsal cheilectomy with an oblique resection of the phalanx base (preserving the flexor hallucis brevis attachment) combined with interposition arthroplasty of the dorsal joint capsule sewn to the plantar soft tissues is presented. Numerous surgical procedures have been described for the treatment of hallux rigidus, including dorsal cheilectomy, resection arthroplasty, joint replacement, and arthrodesis. The Keller procedure has been abandoned by many because of shortening of the great toe and loss of push-off power. The modified oblique Keller technique described here allows for intraoperative transition from cheilectomy to resection arthroplasty with what appears to be a satisfactory outcome, maintaining plantarflexion power and hallux length.
