ABSTRACT
The incidence of avascular necrosis of the metatarsal head following distal first metatarsal osteotomy combined with adductor tendon release has not been documented in a large series of patients. Of 82 consecutive procedures in 64 patients performed between 1986 and 1988, 42 patients (58 procedures) were available for clinical and radiographic examination. Average follow-up was 2.5 years (range 1.0-4.2 years). There were 35 L-shaped and 23 chevron osteotomies which were combined with a lateral soft tissue release that included adductor tenotomy. Preoperative hallux valgus angle averaged 25 degrees (range 15-40 degrees), and intermetatarsal angle averaged 12 degrees (range 5-24 degrees). Follow-up amount of correction averaged 13 degrees and 5 degrees, respectively. Eighty-four percent of patients were satisfied with their result. There was one case of avascular necrosis. The patient was asymptomatic at 4.2 years' follow-up, and the remaining patients included two with infections, one hallux varus, and no nonunions.
