RESUMEN
BACKGROUND: Bunionette deformity of the fifth metatarsal infrequently requires operative treatment. This study presents the long-term results of a simple operative technique. METHODS: Forty-four distal metatarsal medial slide osteotomies with pin fixation were performed for symptomatic bunionette deformity in 30 patients. After an average of 7 years and 8 months (range 69 to 110 months), 30 feet in 21 patients were available for clinical and radiographic evaluation. RESULTS: The patients' subjective assessment was excellent and good in 81% and fair and poor in 19% of feet. The mean pain score on a visual analogue scale was 1.8 (range 0 to 7) and the mean American Orthopaedic Foot and Ankle Society (AOFAS) score was 88.2 (range 47 to 100). Postoperative complications included pin track infection in three feet and delayed union in one. One patient developed transfer metatarsalgia and another patient had repeat surgery for recurrent symptoms on both feet after 5 years. CONCLUSIONS: This procedure combines technical simplicity with satisfactory and predictable long-term results in the operative treatment of bunionette deformity in the lateral forefoot.

OBJECTIVE: Correction of a symptomatic hallux valgus deformity. INDICATIONS: A hallux valgus deformity in which the intermetatarsal angle I-II exceeds 15 degrees and the shaft of the first metatarsal is broad enough to allow a rotational osteotomy. CONTRAINDICATIONS: Hypermobility of the first ray. Severe osteoporosis. Degenerative arthritis of the first metatarsophalangeal joint. SURGICAL TECHNIQUE: Longitudinal incision over the first intermetatarsal space. Division of the metatarsosesamoid ligament together with the tendon of the adductor hallucis muscle. Opening of the lateral articular capsule of the first metatarsophalangeal joint allowing a tension-free realignment of the head of the first metatarsal with the sesamoids. Medial longitudinal incision along the first metatarsal starting over the medial cuneiform bone and ending at the proximal phalanx of the great toe. Oblique osteotomy of the proximal two thirds of the first metatarsal in a proximal dorsal to distal plantar direction and lateral rotation of the distal fragment around a proximally placed 3-mm AO screw. Additional fixation with one BOLD screw. Trimming of the protruding bone and of bunion. Medial metatarsophalangeal capsulorraphy. RESULTS: Between September 1998 and October 1999, 76 feet underwent a Ludloff osteotomy. Patients were followed up clinically and radiographically for 36 months (24-56 months). The mean hallux valgus angle was reduced from 37 degrees to 14 degrees and the mean intermetatarsal angle I-II from 18 degrees to 9 degrees. Using a four-point scale 81% of the patients were satisfied or very satisfied with the result of the operation. 95% of them felt no or very mild pain.
