INTRODUCTION
This study compares early failure rates of sliding hip screw (SHS) and cannulated screw (CS) constructs in young patients.
METHODS
Patients <60 years of age, with displaced femoral neck fractures treated with CS or SHS fixation were included. Primary outcome was failure within 6 months.
RESULTS
One patient (3%) with SHS fixation and 6 patients (21%) with CS fixation failed within 6 months (P = 0.04). Regression analysis demonstrated type of fixation (P = 0.005) and reduction quality (P = 0.04) are independent predictors of early failure.
CONCLUSIONS
SHS constructs demonstrate a significantly lower short-term failure rate than CS constructs.
引言
本研究比较了年轻患者中滑动髋螺钉（SHS）和空心螺钉（CS）固定结构的早期失败率。
方法
纳入年龄<60岁、采用CS或SHS固定治疗的移位型股骨颈骨折患者。主要结局为6个月内失败。
结果
1例（3%）接受SHS固定的患者和6例（21%）接受CS固定的患者在6个月内失败（P = 0.04）。回归分析表明，固定类型（P = 0.005）和复位质量（P = 0.04）是早期失败的独立预测因素。
结论
SHS固定结构的短期失败率显著低于CS固定结构。
