Abstract: Objective To explore the risk factors on impact of early dislocation after hip arthroplasty,and provide patients with individ-ualized treatment programs. Methods We retrospectively analyzed the clinical data of displaced femoral neck fractures in 247 patients who accepted hip arthroplasty from January 2006 to December 2011,and a total of 8 potential factors associated with occurrence of early dislocation were evaluated by univariate analysis and multivariate logistic regression analysis. Results The univariate analysis showed that sex,surgical approach and femoral head size were correlated with early dislocation (P<0. 05). Multivariate logistic regression analysis showed that female (OR=1. 862),posterolateral surgical approach (OR=3. 478),the use of 22 mm femoral heads (OR=2. 558)were independent risk factors (P<0. 05). And use of≥30 mm femoral heads(OR=0. 635) was a protective factor(P<0. 05). Conclusion Occurrence of early dislo-cation after hip arthroplasty is mainly correlated with many factors,various risk factors should be taken into account in preoperative and intrao-perative and choose the optimal individualized treatment plan.
