Abstract

220 patients with femoral neck fractures were randomly treated with either a Rydell nail (n 110) or two LIH hook pins (n 110). The age, sex, and displacement patterns were similar in both group. All the patients were operated on by orthopedic specialists and followed clinically and radiographically for 2 years or until death. The mortality at 2 years was similar (28 percent) in both groups. Among 154 survivors, early redisplacement or nonunion was recorded in 19 percent of the Rydell-nailed fractures and 32 percent of the LIH-pinned fractures. In nondisplaced fractures, complications occurred in 8/30 Rydell cases compared with 3/16 in the LIH group. In displaced fractures, complications occurred in 21/48 Rydell cases compared with 28/60 in the LIH group.

摘要

220例股骨颈骨折患者被随机分为两组，分别接受Rydell钉治疗（110例）或两枚LIH钩钉治疗（110例）。两组患者的年龄、性别和移位类型相似。所有患者均由骨科专家进行手术，并进行了2年的临床和影像学随访，直至死亡。两组患者2年时的死亡率相似（均为28%）。在154名幸存者中，Rydell钉固定骨折的早期再移位或骨不连发生率为19%，LIH钉固定骨折为32%。在无移位骨折中，Rydell组30例中有8例出现并发症，而LIH组16例中有3例；在移位骨折中，Rydell组48例中有21例出现并发症，而LIH组60例中有28例。
