The objective of this retrospective study was to compare the efficacy of the double reverse traction repositor (DRTR) and traction table with proximal femoral nailing antirotation (PFNA) in the treatment of unstable intertrochanteric fractures. : Data from 66 patients (36 patients treated with the traction table and 30 patients treated with DRTR) with unstable intertrochanteric fractures were reviewed from January 2017 to June 2017. The demographics, fracture characteristics, surgical data, and prognostic parameters were collected to compare the differences between the two groups. : The collodiaphyseal angle (CDA) was significantly lower in the DRTR group than in the traction table group (129.37° ± 7.47 and 135.67° ± 6.95, respectively, p < 0.001). The open reduction rate was significantly lower in the DRTR group than in the traction table group (3.3% and 13.9%, respectively, p < 0.001). No significant differences were found in the demographics, fracture characteristics, other surgical data, or prognostic parameters between the two groups. : DRTR can facilitate safe, effective, and minimally invasive treatment of unstable intertrochanteric fractures with PFNA.
本回顾性研究旨在比较双反牵引复位器（DRTR）与牵引桌联合股骨近端防旋髓内钉（PFNA）治疗不稳定型股骨转子间骨折的疗效。
对 2017 年 1 月至 6 月间收治的 66 例不稳定型股骨转子间骨折患者（牵引桌治疗组 36 例，DRTR 治疗组 30 例）的临床资料进行回顾性分析。收集两组患者的一般资料、骨折特征、手术相关数据及预后参数，对比两组患者的差异。
DRTR 组患者的骨干骺端角（CDA）显著低于牵引桌治疗组（129.37°±7.47 和 135.67°±6.95，p<0.001），复位质量优良率也显著低于牵引桌治疗组（3.3%和 13.9%，p<0.001）。两组患者在一般资料、骨折特征、其他手术相关数据或预后参数方面均无显著差异。
DRTR 可辅助 PFNA 安全、有效、微创地治疗不稳定型股骨转子间骨折。
