Abstract
Between 1991 and 1995, 96 patients (114 feet) were treated with a proximal crescentic metatarsal osteotomy and distal soft-tissue procedure for moderate to severe hallux valgus deformity [intermetatarsal (IM) angle > 15°, or hallux valgus (HV) angle > 30°]. At an average follow-up of 26 months, 8 men and 62 women (86 feet) with a mean age of 53.2 years were retrospectively reviewed. The HV angle averaged 41.1° preoperatively and 14.6° postoperatively. The respective values for the IM angle were 17.8° and 7.8°. Neither the average metatarsal shortening of 3 mm nor the dorsal angulation at the osteotomy site seen in 9% of cases evidenced any clinical significance at follow-up. Patient satisfaction was excellent or good in 91%, and the mean Mayo Clinic Forefoot Score (total 75 points) improved from 37.2 to 61.1 points. Complications included 8 cases of hallux varus and 5 cases of hardware failure. Based on this first study exclusively focusing on moderate to severe hallux valgus deformity, we conclude that proximal first metatarsal osteotomy in combination with a lateral soft-tissue procedure is effective in correcting moderate to severe symptomatic hallux valgus deformity with metatarsus primus varus (IM angle > 15° or HV angle > 30 °).
