Adolescent Bunion Deformity Treated with Double Osteotomy and Longitudinal Pin Fixation of the First Ray.Peterson, Hamlet A. M.D.; Newman, Stephen R. M.D.Journal of Pediatric Orthopaedics: January 1993 Article: PDF Only Abstract Abstract Surgical correction of bunion deformity in adolescents is performed infrequently. Double osteotomy and longitudinal pin fixation of the first ray was performed on 15 feet. This procedure is technically easy, provides excellent correction and stability, and has a low rate of recurrence of deformity. Five numerical determinations were obtained from preoperative, intraoperative, and final follow-up radiographs. They included intermetatarsal angle, first-fifth metatarsal angle, and metatarsophalangeal angle, first-second metatarsal distance, and length of the first and second metatarsals. The mean length of follow-up was 32.5 months. The operation is indicated for severe deformities and should be applicable to adults. (C) Lippincott-Raven Publishers.
