Fixation of femoral neck fractures. A four-flanged nail versus threaded pins in 200 cases

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.
