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\u20134.2 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\u00b0 (range 15\u201340\u00b0), and intermetatarsal angle averaged 12\u00b0 (range 5\u201324\u00b0). Follow-up amount of correction averaged 13\u00b0 and 5\u00b0, 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.<\/jats:p>","DOI":"10.1177\/107110079401500201","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"59-63","source":"Crossref","is-referenced-by-count":92,"title":["Avascular Necrosis of the First Metatarsal Head: Incidence in Distal Osteotomy Combined with Lateral Soft Tissue Release"],"prefix":"10.1177","volume":"15","author":[{"given":"Drew A.","family":"Peterson","sequence":"first","affiliation":[{"name":"Departments of Orthopedics and Clinical Investigation, Naval Medical Center, San Diego, California."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey L.","family":"Zilberfarb","sequence":"additional","affiliation":[{"name":"Departments of Orthopedics and Clinical Investigation, Naval Medical Center, San Diego, California."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie A.","family":"Greene","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Kaiser Permanente Hospital, San Dio, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert C.","family":"Colgrove","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Kaiser Permanente Hospital, San Dio, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1994,2,1]]},"reference":[{"key":"bibr1-107110079401500201","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1097\/00003086-198106000-00007","volume":"157","author":"Austin D.","year":"1981","journal-title":"Clin.
