Two methods of internal fixation for cervical hip fractures were compared in a "randomized to surgeons" type of study. One hundred patients were treated with the Rydell four-flanged nail and 100 with the Gouffon pins. Redisplacement, nonunion, or segmental collapse occurred in 27 patients operated on with the Rydell nail and in 29 patients operated on with the Gouffon pins. According to the actuarial method of follow-up, the failure rates after 2 years were 31 and 33 percent in the two groups.
在一项“随机分配给外科医生”类型的研究中，对两种治疗股骨颈骨折的内固定方法进行了比较。100例患者接受了Rydell四翼钉治疗，100例患者接受了Gouffon针治疗。使用Rydell钉手术的27例患者以及使用Gouffon针手术的29例患者出现了再移位、骨不连或节段性塌陷。根据精算随访方法，两组患者2年后的失败率分别为31%和33%。
