A study of 76 displaced femoral neck fractures treated by reduction and Knowles pins or AO (ASIF) cancellous bone screws was carried out. Fixation failure within 3 months occurred in 17 cases (22%). Advanced age, inaccurate reduction, a poor mental state of the patient, the number of Knowles pins used, and the preinjury functional ability of the patient are significant risk factors for fixation failure. Neurological disease, the type of fracture according to Garden, delay before operation, and the method of fixation are not significantly related to fixation failure.
对76例采用复位及诺尔斯针或AO（ASIF）松质骨螺钉治疗的移位型股骨颈骨折进行了一项研究。17例（22%）在3个月内出现固定失败。高龄、复位不准确、患者精神状态差、诺尔斯针的使用数量以及患者伤前的功能能力是固定失败的重要危险因素。神经疾病、根据Garden分型的骨折类型、手术前的延迟时间以及固定方法与固定失败无显著相关性。
