Abstract

Abstract:

BACKGROUND: The traditional surgical treatment of proximal tibial fractures has extensive dissection of the fracture site, and affects local blood circulation, increases the incidence of delayed union and nonunion. In recent years, the rising minimally invasive internal fixation system can protect the local soft tissue and blood circulation to the maximum extent, and provide better conditions for fracture healing. The application of new spreader also solves the problems of stability and durability of traditional manual traction reduction, and the combination of the two is gradually concerned.

OBJECTIVE: To explore the effect of a new minimally invasive spreader assisted reduction and less invasive stabilization system for the treatment of proximal tibial fractures.

METHODS: Twenty-two patients with proximal tibial fractures treated from May 2016 to October 2019 were studied and randomly assigned to control group and observation group (n=11 per group). Patients in the control group were treated with conventional manipulative reduction and conventional incision plate internal fixation. Patients in the observation group were treated with a new minimally invasive spreader assisted reduction and less invasive stabilization system. This study was approved by the Ethics Committee of Fifth Hospital, Guangzhou Medical University.

RESULTS AND CONCLUSION: Compared with the control group, Rasmussen knee function score was better in the observation group at the last follow-up. Intraoperative blood loss, operation time, length of hospital stay, and weight-bearing time in the observation group were better than those in the control group. Postoperative complications such as joint limitation and delayed fracture healing were less in the observation group than in the control group. However, the healing time was not statistically significant between the two groups. Moreover, infection of the incision and loosening and fracture of the internal fixator were not statistically significant between the two groups. These indicated that the application of a new minimally invasive spreader combined with less invasive stabilization system for proximal tibial fractures can reduce surgical reduction time and local soft tissue damage, which is beneficial to early functional exercise and can reduce postoperative complications.
