Abstract
OBJECTIVE: The purpose of this prospective study was to compare the double reverse traction repositor (DRTR) and manual traction in retrograde intramedullary nailing (RE-IMN) for femoral shaft fractures. PATIENTS AND METHODS: Seventy-seven patients with femur shaft fractures were randomized to undergo surgery with either DRTR or manual traction (MT) to facilitate RE-IMN between January 2018 and January 2019. Demographics, fracture characteristics, surgical data, post-operative complications, and functional outcomes were assessed. Data from 72 patients completing the final follow-up (12 months) were analysed in this study. RESULTS: The average number of intra-operative perspectives in the DRTR group was 27.7, which was significantly reduced compared with that in the MT group (31.3, p < 0.001). Fewer assistants were required in the DRTR group compared with the MT group (1.1 vs 1.9, p < 0.001). Fewer patients with open reduction were discovered in the DRTR group compared with the MT group (2.8 vs 19.4, p=0.024). Demographics, fracture characteristics, other surgical data, and prognostic parameters were comparative between the two groups. CONCLUSIONS: The DRTR can be effectively and safely used to treat femur shaft fractures with RE-IMN. The DRTR achieves similar results as MT and is also superior to MT in terms of intra-operative perspectives, the number of assistants, and the open reduction rate.
