Objective To investigate clinical effect by proximal femoral nail antirotation (PFNA) in the treatment of hip fracture. Methods A total of 68 hip fracture patients were randomly divided into treatment group and control group, with 34 cases in each group. The treatment group received proximal femoral nail antirotation for treatment, and the control group received basic therapy. Clinical effects were compared between the two groups. Results There were 26 effective cases, 6 improved cases and 2 ineffective cases in the treatment group, with total effective rate as 94%. In the control group there were 15 effective cases, 6 improved cases and 13 ineffective cases, with total effective rate as 62%. The treatment group had higher total effective rate than the control group, and their difference had statistical significance (P<0.05). Conclusion Implement of proximal femoral nail antirotation can effectively fixate hip fracture, and relieve pain with precise effect.%目的：探讨防旋股骨近端髓内钉(PFNA)治疗髋部骨折的临床疗效。方法68例髋部骨折患者，随机分为治疗组和参照组，各34。治疗组应用防旋股骨近端髓内钉治疗，参照组行基础治疗。对比两组临床疗效。结果治疗组有效26例、好转 6例、无效2 例 ， 总有效率为94%；参照组有效15例、好转 6例、无效13例，总有效率为62%；治疗组总有效率高于参照组，差异具有统计学意义(P<0.05)。结论应用防旋股骨近端髓内钉能够有效的对髋部骨折位置进行治疗固定，减轻患者的痛苦，效果显著。
