Abstract:

BACKGROUND: Intramedullary nail fixation for intertrochanteric fractures assisted by orthopedic robot navigation is a new surgical method, and there are few studies comparing with traditional intramedullary nailing.
OBJECTIVE: To compare the efficacy of intramedullary nail fixation for intertrochanteric fractures assisted by orthopedic robot navigation and traditional surgery, and to analyze the advantages and disadvantages of intramedullary nail fixation for femoral intertrochanteric fractures assisted by orthopedic robot navigation.
METHODS: From April 2015 to December 2017, 59 patients with intertrochanteric fracture were collected from Department of Orthopedics, Affiliated Hospital of Chengdu University. According to the method of operation, there were two groups. Among them, 28 cases underwent intramedullary nail fixation assisted by orthopedic robot navigation (orthopedic robot surgery group), and 31 cases underwent traditional intramedullary nail fixation (traditional surgery group). All patients signed informed consent. The protocol was approved by the Ethics Committee of Affiliated Hospital of Chengdu University. The operation time, the times of intraoperative fluoroscopy, the frequency of guide pin inserted into femoral marrow cavity, and the amount of intraoperative bleeding were recorded and compared between groups. One year after operation, fracture healing and hip function were observed.
RESULTS AND CONCLUSION: (1) Compared with the traditional surgery group, the operation time was shorter; the times of intraoperative fluoroscopy was fewer; the frequency of guide pin inserted into femoral marrow cavity was lower; the amount of surgical bleeding was less; and the one-time success rate of the guide pin inserted into femoral marrow cavity was higher in the orthopedic robot surgery group (all P < 0.05). (2) One year after surgery, fracture healing was observed in both groups, and no internal fixator failure or fracture displacement occurred. The Harris score of hip joint in the orthopedic robot surgery group was higher than that in the traditional surgery group (P < 0.05). There was no significant difference in excellent and good rate between the two groups (P > 0.05). (3) Intramedullary nail fixation for intertrochanteric fractures assisted by orthopedic robot navigation is a better ideal method with short operation time, less trauma, and less radiation during operation.
