- Abstract: Objective To investigate the independent risk factors of postoperative femoral head necrosis for pediatric femoral neck fractures.Methods The clinical data of 122 children with femoral neck fracture who underwent surgery in our hospital from July 2008 to July 2021 were retrospectively analyzed.The femoral head necrosis was counted,and the children were divided into the femoral head necrosis group and the femoral head normal group according to the presence of femoral head necrosis,then the risk factors of femoral head necrosis were analyzed.Results Of the 122 children,22 cases(18.03％)had femoral head necrosis.The postoperative femoral head necrosis for pediatric femoral neck fractures may be related to the age,Delbet classification,initial displacement degree,injury mechanism,operation time,internal fixation method and reduction quality(P＜0.05),while which has no significant correlation with the gender,side,time from injury to operation,or reduction method(P＞0.05).The results of Logistic regression analysis showed that age＞10 years,Delbet type of Ⅰ to Ⅱ,initial displacement degree of type Ⅲ,high-energy injury and unacceptable reduction were the independent risk factors of postoperative femoral head necrosis for pediatric femoral neck fractures(P＜0.05).Conclusion Older children,or patients with Delbet type of Ⅰ to Ⅱ,large degree of initial displacement,high-energy injury,and unacceptable reduction are the independent risk factors of postoperative femoral head necrosis for pediatric femoral neck fractures.
