Femoral neck fracture is a common fracture in orthopedic practice. This study aimed to compare the clinical outcomes between the femoral neck system and dynamic hip system blade for the treatment of femoral neck fracture in young patients.
This retrospective study included 43 and 52 patients who underwent treatment for femoral neck fracture with the femoral neck system and dynamic hip system blade, respectively, between August 2019 and August 2020. Operative indexes, including operation duration, blood loss, incision length, postoperative complications (femoral neck shortening, non-union, screw pull-out, femoral head necrosis), and Harris scale scores were recorded and analyzed.
Compared to that with the dynamic hip system blade, the femoral neck system showed significantly less operation duration (femoral neck system vs. dynamic hip system blade: 47.09 ± 9.19 vs. 52.90 ± 9.64, = 0.004), less blood loss (48.53 ± 10.69 vs. 65.31 ± 17.91, < 0.001), and shorter incision length (4.04 ± 0.43 vs. 4.93 ± 0.53, < 0.001). Femoral neck shortening was significantly lower with the femoral neck system than with the dynamic hip system blade (3.93 ± 2.40, = 39 vs. 5.22 ± 2.89, = 44, = 0.031). No statistical differences were observed between the two groups in nonunion, screw pull-out, and femoral head necrosis. In addition, the latest follow-up Harris scale score was significantly higher with the femoral neck system than with the dynamic hip system blade (92.3 ± 4.5 vs. 89. 9 ± 4.9, = 0.015).
The femoral neck system results in less trauma, less femoral neck shortening, and better hip joint function than the dynamic hip system blade for the treatment of femoral neck fracture in young patients.
股骨颈骨折是骨科临床常见的骨折类型。本研究旨在比较股骨颈系统与动力髋系统刀片治疗年轻患者股骨颈骨折的临床疗效。
本回顾性研究纳入了2019年8月至2020年8月期间分别采用股骨颈系统和动力髋系统刀片治疗股骨颈骨折的43例和52例患者。记录并分析手术指标，包括手术时间、出血量、切口长度、术后并发症（股骨颈缩短、不愈合、螺钉拔出、股骨头坏死）以及Harris评分。
与动力髋系统刀片相比，股骨颈系统的手术时间明显更短（股骨颈系统 vs. 动力髋系统刀片：47.09±9.19 vs. 52.90±9.64，P = 0.004），出血量更少（48.53±10.69 vs. 65.31±17.91，P < 0.001），切口长度更短（4.04±0.43 vs. 4.93±0.53，P < 0.001）。股骨颈系统导致的股骨颈缩短明显低于动力髋系统刀片（3.93±2.40，n = 39 vs. 5.22±2.89，n = 44，P = 0.031）。两组在不愈合、螺钉拔出和股骨头坏死方面未观察到统计学差异。此外，股骨颈系统的末次随访Harris评分明显高于动力髋系统刀片（92.3±4.5 vs. 89.9±4.9，P = 0.015）。
对于年轻患者股骨颈骨折的治疗，股骨颈系统比动力髋系统刀片创伤更小、股骨颈缩短更少且髋关节功能更好。
