DISTAL TIBIA SPIRAL AND COMMINUTED FRACTURES: CAN ABSOLUTE ANATOMICAL REDUCTION BE COMPROMISED?

Abstract

Purpose: Minimally invasive plate osteosynthesis (MIPO) is used for the treatment of distal tibial fractures, especially in cases of intra-articular fractures. There are many advantages of MIPO, including preservation of blood supply to the fracture site and enhanced bone healing, however, it is not without complication. The study aimed to elaborate the benefits of MIPO technique in managing distal tibia fractures and to describe the necessities for good union and functional outcome. Methods: A total of 38 patients with distal tibia comminuted and spiral fractures, having closed distal tibia AO/OTA 43-A, B or C fractures with or without fibular fractures, were included. All the cases were assessed for union time, complications and functional outcomes. Binomial regression using [Formula: see text] v3.6.0 was used to assess the success of MIPO based on four-cortex alignment. [Formula: see text] value [Formula: see text] was considered statistically significant. Results: The mean operative time was 70[Formula: see text]min. All 38 tibial fractures united and the mean union time was found to be 18 weeks. Five cases were noted to have complications (four superficial infections and one implant failure). Out of 38 patients, 28 (majority) showed excellent functional outcomes as assessed by the American Orthopaedic Foot and Ankle Society score, i.e. a score of [Formula: see text]90. Conclusion: MIPO is a good method for the management of tibial fractures with extra-articular and intra-articular involvement, with good union even when absolute four cortical contact is not achieved.
