股骨颈骨折后股骨头坏死的相关因素分析

目的 探讨股骨颈骨折后出现股骨头坏死的相关因素。方法 于2016年1月~2017年10月，对本院收治的股骨颈骨折手术患者100例作为研究对象，收集患者的临床资料，分析股骨颈骨折后发生股骨头坏死的危险因素，进而为临床有效防治提供参考。结果 所有患者均获得随访，随访时间为10~21个月，平均（16.73±2.21）个月。有10例患者发生股骨头坏死，发生率为10.00%。单因素分析显示复位质量、手术间隔时间、囊内是否减压是导致股骨头坏死的危险因素。多因素Logistic回归分析显示囊内是否减压、复位质量是影响股骨头坏死的独立危险因素。结论 囊内是否减压、骨折复位质量是影响股骨头坏死的主要因素，其中预后影响最大的是骨折复位质量，患者股骨颈骨折后需尽快实施高质量复位操作，并让囊内充分减压，以防止股骨头坏死的发生。

Analysis of Related Factors of Femoral Head Necrosis After Femoral Neck Fracture

Objective To investigate the related factors of femoral head necrosis after femoral neck fracture. Methods From January 2016 to October 2017, 100 patients with femoral neck fractures admitted to our hospital were selected as subjects. The clinical data of patients were collected to analyze the risk factors of femoral head necrosis after femoral neck fracture. Provide effective reference for prevention and control.Results All patients were followed up for 10 to 21 months with an average of (16.73 ± 2.21) months. Femoral head necrosis occurred in 10 patients, with an incidence of 10.00%. Univariate analysis showed that the quality of the reduction, the interval between the procedures, and whether the decompression in the capsule was a risk factor for necrosis of the femoral head. Multivariate logistic regression analysis showed that decompression and mass reduction in the capsule were independent risk factors for femoral head necrosis. Conclusion Whether the decompression or fracture reduction quality in the capsule is the main factor affecting the femoral head necrosis, the most important prognosis is the quality of fracture reduction. After the femoral neck fracture, the patient needs to perform high-quality reduction operation as soon as possible, and fully decompress the capsule. To prevent the occurrence of femoral head necrosis.
