The clinical application of double reverse traction repositor in the treatment of posterolateral tibial plateau fractures

Abstract

Abstract Objective The aim of this study was to evaluate the effect of double reverse traction repositor (DRTR) in the treatment of posterolateral tibial plateau fractures. Methods From November 2015 to July 2017, the patients with posterolateral tibial plateau fractures treated with the DRTR in the Third Hospital of Hebei Medical University were included in the present study. The operation time, intraoperative blood loss, complications, the Rasmussen’s clinical and radiological scores, the value of articular surface depression and plateau widening, the tibial plateau angle (TPA) and posterior slope angle (PSA) were measured on the preoperative, postoperative radiographs and last follow-up radiographs. Results The average follow-up was 16.4 ± 3.8 months. The average operation time was 129 ± 40.4 min. Average blood loss was 210 ± 73.6 ml. At the last follow-up, the average step-off of articular surface and plateau widening were 1.60 ± 0.94 and 1.91 ± 1.73 mm, respectively. There was no significant difference in the average value of articular surface step-off and articular surface widening between the postoperative and the last follow-up (P2 = 0.067, P2 = 0.731). At the last follow-up, the average TPA and PSA were 88.47 ± 2.84 ° and 11.05 ± 4.31 °, respectively. There was no significant difference in the average values of TPA and PSA between the postoperative and the last follow-up (P = 0.761, P = 0.937). At the last follow-up, the average radiological Rasmussen score was 14.74 ± 1.48 (12–18). The average functional Rasmussen score was 27.00 ± 2.90 (19–30). Conclusion Our technique has the characteristics of limited soft tissue exposure, short operation time, and few complications.
