The main objective of this study was to evaluate the failure rate following operations of undisplaced and displaced cervical hip fractures with a dynamic hip screw compared with 3 parallel screws.
The study was retrospective. The minimum follow-up time was 1 year. The data tta collested between January 1990 and December 1993.
University Hospitals.
A total of 456 patients (352 women and 104 men) with cervical hip fractures were included. The mean age was 80 years (range 51-100 years).
This was internal fixation of the fractured hip with a dynamic hip screw or 3 parallel screws.
Failure was defined as nonunion, fixation failure or avascular necrosis and reoperation was found indicated. The 3 months mortality rate, the wound infection rate, the delay between admission and time of surgery and the blood transfusion requirement were also recorded.
A total of 456 cervical hip fractures were operated with a dynamic hip screw or 3 parallel screws. The failure rate for fractures treated with a dynamic hip screw was 14/98 = 14% for Garden 1 + 2 fractures and 43/108 = 40% for Garden 3 + 4 fractures. The failure rate for fractures treated with 3 parallel screws was similar: 23/154 = 15% for Garden 1 + 2 fractures and 38/196 = 40% for Garden 3 + 4 fractures. The average follow-up time was 2.5 years.
Operation of cervical hip fracture with a dynamic hip screw or 3 parallel screw seem to give similar results.
本研究的主要目的是评估使用动力髋螺钉与3枚平行螺钉治疗无移位和移位型股骨颈骨折后的失败率。
本研究为回顾性研究。最短随访时间为1年。数据收集于1990年1月至1993年12月。
大学医院。
共纳入456例股骨颈骨折患者（352例女性和104例男性）。平均年龄为80岁（范围51 - 100岁）。
采用动力髋螺钉或3枚平行螺钉对骨折的髋部进行内固定。
失败定义为骨不连、内固定失败或缺血性坏死且需再次手术。还记录了3个月死亡率﹑伤口感染率﹑入院至手术的间隔时间以及输血需求。
共对456例股骨颈骨折采用动力髋螺钉或3枚平行螺钉进行手术。动力髋螺钉治疗的Garden 1 + 2型骨折失败率为14/98 = 14%，Garden 3 + 4型骨折失败率为43/108 = 40%。3枚平行螺钉治疗的骨折失败率相似：Garden 1 + 2型骨折为23/154 = 15%，Garden 3 + 4型骨折为38/196 = 40%。平均随访时间为2.5年。
使用动力髋螺钉或3枚平行螺钉治疗股骨颈骨折似乎效果相似。
