We compared fixation with hook pins or sliding screw plate in a prospective randomized study of 222 patients with a cervical hip fracture. Radiographic evidence of early redisplacement, nonunion, or late segmental collapse was found in 43 of 122 patients operated on with two hook pins and in 40 of 100 patients operated on with the sliding screw plate. According to the actuarial method, the failure rate after 2 years was 38% with hook pins and 46% with screw plates, which not is a significant difference. Due to early redisplacement, reoperation with an endoprosthesis was performed within 0.5 (2) years in 11 (22) patients in the hook-pin group and in 4 (17) patients in the sliding-screw plate group.
在一项针对222例颈椎骨折患者的前瞻性随机研究中，我们比较了使用钩钉或滑动螺钉钢板进行固定的效果。在122例接受两枚钩钉手术的患者中，有43例出现早期再移位、骨不连或晚期节段性塌陷的影像学证据；在100例接受滑动螺钉钢板手术的患者中，有40例出现上述情况。根据精算方法，2年后钩钉固定的失败率为38%，螺钉钢板固定的失败率为46%，二者无显著差异。由于早期再移位，钩钉组11例（22%）患者和滑动螺钉钢板组4例（17%）患者在0.5（2）年内接受了人工关节置换翻修手术。
