A novel retrograde tibial nail for treatment of distal tibial fracture: preliminary results / 中华创伤骨科杂志

ABSTRACT

Objective:To investigate the effects of a novel retrograde tibial nail (RTN) in the treatment of distal tibial fractures.Methods:A retrospective study was conducted in the 11 patients with distal tibial fracture who had been admitted to Department of Traumatic Orthopedics, The Second Affiliated Hospital, Hengyang Medical School from July 2020 to July 2021. There were 5 male and 6 females, aged from 18 to 70 years (average 54.7 years). By the AO/OTA classification, there were 7 extra-articular distal fractures (3 cases of type 43-A1, 3 cases of type 43-A2 and one type 43-A3) and 4 intra-articular fractures (2 cases of type 43-C1 and 2 cases of type 43-C2); by the Gustilo classification, there were 7 closed fractures and 4 open fractures (2 cases of type I and 2 cases of type Ⅱ). All fractures were fixated with a novel RTN. Deformities like distal tibial varus and valgus as well as fracture-related complications were observed after operation while the curative effects evaluated by the ankle-hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS).Results:This cohort was followed up for an average of 7.4 months (from 5 to 12 months). All patients obtained clinical union and recovered daily life and work. Radiographic evaluation showed no distal tibial varus or valgus. There were no such complications as postoperative infection, exposure of bone and internal fixation, compartment syndrome, or neurovascular lesion. According to the ankle-hindfoot score of AOFAS, 7 cases were excellent and 4 cases good.Conclusion:This novel retrograde tibial nail may result in good efficacy in the treatment of distal tibial fracture, but its advantages still need further verification.
