Abstract

A buttonhole deformity of the finger is characterized by flexion of the pmximal interphalangeal joint and hyperextension of the terminal interphalangeal joint. When the central slip of the extensor tendon and the triangular ligament are ruptured,(or severed) on the base of the middle phalanx, buttonhole deformity will result.This article is based on clinical and follow up studies of 5 patients with buttonholedeformities. Five cases were treated by the modified Littler method and were followed from 4 months to 24 months postoperatively and good results were obtained in all cases.
