• BACKGROUND
    • Currently, we found that double reverse traction repositor (DRTR) is a treatment with operation convenience and fast in our clinical work. However, the clinical efficacy and safety of DRTR in the reduction of unstable intertrochanteric fractures in elderly patients remain unknown. Therefore, the study aimed to compare the clinical efficacy and safety of DRTR and traction table (TT) in the reduction of unstable intertrochanteric fractures in elderly patients.
  • METHODS
    • From October 2018 to December 2020, the elderly patients with unstable intertrochanteric fractures were reviewed. 22 patients treated with TT and 20 patients treated with DRTR met the inclusion criteria of this study, and baseline clinical characteristics were recorded. The reduction time, operation time, incision length and intraoperative blood loss were reviewed. The safety outcome was assessed by postoperative complications, and the efficacy outcomes were evaluated by the fracture healing time based on the radiographs conducted at each follow-up (1, 3, 6, 12 months after surgery) and hip function (hip flexion, Harris Hip Score) at the final follow-up (12 months after surgery).
  • RESULTS
    • There were no significant differences in terms of demographics and fracture characteristics of cases enrolled. In DRTR group, the average intraoperative reduction time [(34.8±7.6) min] and the average operation time [(87.1±12.2) min] were superior to those [(56.6±9.3); (123.1±15.0) min] in TT group (P<0.0001). However, there were no statistical significance in terms of the average incision lengths [(6.4±0.9) vs. (6.8±1.1) cm; P=0.1619], , the average intraoperative blood loss [(152.6±22.9) vs. (146.8±20.7) mL; P=0.3941], the average fracture healing times [(13.8±1.5) vs. (14.4±1.8) weeks; P=0.2350] and the average Harris hip score a year after operation [(84.4±6.6) vs. (82.7±7.2); P=0.4496] between the two groups. One patient in TT group experienced lower extremity intermuscular venous thrombosis postoperatively. No other operation-related complications were observed postoperatively nor during follow-up.
  • CONCLUSIONS
    • Minimally invasive reduction with DRTR in unstable intertrochanteric fractures could effectively shorten the intraoperative reduction time and operation time in this study. Therefore, minimally invasive reduction with DRTR might be a good choice for intertrochanteric reduction of unstable intertrochanteric fractures.
