BACKGROUND: Osteosynthesis of @entity2249 is particularly indicated in @entity1 aged under 60 years. A prolonged interval between the @entity174 and surgical fixation has been associated with @entity2530 ( @entity2530 ) of the femoral head. The primary objective of this study was to evaluate the association between the time to surgery and the development of complications in @entity1 with @entity2249 . METHODS: @entity1 with displaced @entity2249 (Garden III or IV) who underwent fixation with three cannulated screws in the inverted triangle configuration from January 2009 to December 2010 were evaluated retrospectively for the development of orthopaedic complications. @entity1 were divided into two groups according to the time to surgery (within 7 days or more than 7 days). Complication rates were compared between the two groups. Regression analyses were performed to assess the risk factors for complications. RESULTS: Thirty-one @entity1 were included in the study; the duration of follow-up ranged from 24 to 50 months. The time from @entity174 to surgery ranged from 3 to 18 days. Fifteen @entity1 underwent surgery within 7 days, and 16 @entity1 underwent surgery after 7 days. There were four cases of femoral @entity39 . One @entity1 had an associated @entity281 ; one @entity1 experienced non-union, and another @entity177 . There were no statistically significant differences in the overall rate of complications between the groups (p = 0.999). None of the preoperative parameters or @entity174 characteristics were predictive factors for complications. The only factor associated with the development of complications was inadequate @entity174 reduction in the anteroposterior (AP) view (odds ratio [OR] = 35.50, 95% confidence interval [CI] = 2.56 to 548.36, p = 0.008). CONCLUSIONS: The interval between the occurrence of the @entity3816 is not associated with the development of complications in @entity2249 . Inadequate @entity174 reduction in the AP view is a predictive factor for complications in these @entity174 .
