OBJECTIVE: @entity1887 @entity174 of the femoral head (SIF) has been reported to be observed mainly in the elderly osteoporotic females and most of the studies on SIF have been made based on female @entity1 . The purpose of this study is to document the clinical characteristics of SIF observed in male @entity1 . @entity1 AND METHODS: Between 2001 and 2011, we have diagnosed 39 consecutive SIF @entity572 in our department, based on imaging studies and/or histologic examinations. Among them, 14 @entity572 (35.8%) were of male SIF @entity1 . Their clinico-radiological characteristics were reviewed. RESULTS: The age range in male SIF @entity1 was 16-62 (ave. 44 years), while that in females was 22-84 (ave. 66 years) (p < 0.001). In male @entity1 , 12 out of 14 @entity572 (86%) healed by non-surgical treatments, while 2 @entity572 (14%) underwent surgical treatments (one case: total hip arthroplasty, and one: anterior rotational osteotomy). On the other hand, in female @entity1 12 out of 25 (48%) healed, while surgical treatments and/or progression of a collapse were observed in 13 @entity572 (52%) (p < 0.05). Both body mass index and bone mineral density showed no significant difference between male and female SIF @entity1 . CONCLUSIONS: SIF in male is observed mainly in their 40s, and their prognosis seems to be good as compared to that in females.
