We evaluated the incidence of avascular necrosis of the femoral head with the use of contemporary techniques for femoral neck fracture fixation. We then sought to determine what potential risk factors influenced the development of avascular necrosis.<\/jats:p>\n                  <jats:p>Between 1990 and 2005, one hundred sixty-three intracapsular femoral neck fractures in 163 patients were treated with internal fixation at our level-I trauma center. All patients were monitored until conversion to total hip arthroplasty or for a minimum of 2 years postoperatively. Ten patients (10 hips) died and 7 patients (7 hips) were lost to follow-up. The remaining 146 patients (146 hips) had a mean 5.2 years of follow-up (range, 3 months to 17 years). The incidence of avascular necrosis was 25.3% (37 hips). The average time to diagnosis of avascular necrosis was 18.8 months (range, 3\u201347 months). Patient sex, age, interval from injury to surgery, and mechanism of injury were statistically not associated with the development of avascular necrosis. The quality of fracture reduction, adequacy of fixation, degree of displacement, and comminution of the posterior cortex were significantly associated. After we controlled for patient and radiographic characteristics, multivariate analyses indicated that the important predictors for avascular necrosis are poor reduction (odds ratio=13.889) and initial displacement of the fracture (odds ratio=4.693).<\/jats:p>","DOI":"10.3928\/01477447-20110317-13","type":"journal-article","created":{"date-parts":[[2011,5,20]],"date-time":"2011-05-20T14:00:19Z","timestamp":1305900019000},"source":"Crossref","is-referenced-by-count":51,"title":["Avascular Necrosis of the Femoral Head After Osteosynthesis of Femoral Neck Fracture"],"prefix":"10.3928","volume":"34","author":[{"given":"Byung-Woo","family":"Min","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Jin","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.58B1.1270491"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199606063342307"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200206000-00012"},{"issue":"156","key":"e_1_3_1_5_2","first-page":"240","article-title":"Mechanical characteristics of bone in femoral capital aseptic necrosis","author":"Brown TD","year":"1981","unstructured":"Brown TD, Way ME, Ferguson AB.
