Two of six stage-IV hips (33%) had good or excellent results. Eighteen of 21 hips (86%) with a combined necrotic angle of 200\u00b0 had good or excellent clinical results compared with only four of nine hips (44%) with a combined necrotic angle of more than 200\u00b0. Six of the eight hips which had fair or poor results were in patients who had received corticosteroids; five of these six hips had lesions with a combined necrotic angle of greater than 200\u00b0 or were in a late stage (stage IV). There were no perioperative complications. <\/jats:p><jats:p> Our results suggest that the trapdoor procedure with autogenous cancellous and cortical bone grafting can be successful in Ficat and Arlet stage-III osteonecrosis of the hip in patients with small- to medium-sized lesions. <\/jats:p>","DOI":"10.1302\/0301-620x.80b1.0800056","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:52:02Z","timestamp":1519213922000},"page":"56-62","source":"Crossref","is-referenced-by-count":259,"title":["The trapdoor procedure using autogenous cortical and cancellous bone grafts for osteonecrosis of the femoral head"],"prefix":"10.1302","volume":"80-B","author":[{"given":"M.
