To discuss the curative effect of the dynamic hip system blade (DHS-blade) on the treatment of femoral neck fractures in elderly patients with osteoporosis.
A retrospective study was conducted to analyse the clinical data of 60 elderly patients with osteoporosis who had been treated for femoral neck fractures with DHS-blade in our department between September 2012 and February 2014. There were 22 males and 38 females with a mean age of (66.8±3.2) years. According to the Singh Index Classification, all the patients'Singh index was below level 3. The Harris criterion and function recovery after operation were analysed.
All patients were followed up for 12-17 months (mean 14 months). No femoral head necrosis, femoral neck shortening, internal fixation loosening or backing out of the nails occurred. Bone nonunion was found in one case and he had a good recovery after total hip arthroplasty. The time for fracture healing ranged from 3-6 months (average 3.5 months). According to Harris criterion, 35 cases were rated as excellent, 22 good, 2 fair and 1 poor. The Harris scale was significantly improved from 28.46±2.35 preoperatively to 91.98±3.26 at 6 months postoperatively (P<0.05).
DHS-blade, being minimally invasive, allowing earlier postoperative exercise and avoiding the complications elicited by traditional internal fixation, is advisable for treatment of femoral neck fractured patients with osteoporosis.
探讨动力髋系统刀片（DHS-刀片）治疗老年骨质疏松性股骨颈骨折的疗效。
进行一项回顾性研究，分析2012年9月至2014年2月在我科采用DHS-刀片治疗的60例老年骨质疏松性股骨颈骨折患者的临床资料。其中男性22例，女性38例，平均年龄（66.8±3.2）岁。根据辛格指数分类，所有患者的辛格指数均低于3级。分析术后Harris标准及功能恢复情况。
所有患者均随访12 - 17个月（平均14个月）。未发生股骨头坏死、股骨颈缩短、内固定松动或钉子退出。发现1例骨不连，全髋关节置换术后恢复良好。骨折愈合时间为3 - 6个月（平均3.5个月）。根据Harris标准，优35例，良22例，可2例，差1例。Harris评分从术前的28.46±2.35显著提高到术后6个月的91.98±3.26（P<0.05）。
DHS-刀片具有微创、术后可早期活动及避免传统内固定引发的并发症等优点，适用于治疗老年骨质疏松性股骨颈骨折患者。
