Keller arthroplasty with autogenous bone graft in the treatment of hallux limitus.

This manuscript presents an alternative surgical procedure in the treatment of hallux limitus. A description of a modified Keller arthroplasty in which the removed base of the proximal phalanx is remodeled and replaced in the first metatarsophalangeal joint is presented. An in-depth review of the procedure has been performed in 220 cases over the last 4 years at the Podiatry Hospital of Pittsburgh, and a study of 25 patients with over 15 months of follow-up is included. Early range of motion, preservation of articular surfaces, no implanted materials, and the option of multiple revisional procedures are the advantages of this procedure.
