Clinico - Radiological Results of Tibial Bicondylar Fractures Managed with Ilizarov Technique with or without Minimal Internal Fixation

ABSTRACT

@#Introduction: Tibial bicondylar fractures are difficult fractures to treat and are usually associated with complications. Materials and methods: Thirty-five patients with Schatzker type V and VI fractures were managed from June 2016 to July 2018 with Ilizarov technique. The mean age of the patients was 46.5 ± 8.9 years, with 28 male and seven female patients. Sixteen patients had Schatzker type V fracture and the remaining had type VI. The functional outcome was assessed by using Modified functional evaluation system by Karlstrom - Olerud and the radiological outcome by Rasmussen's Radiological Score (RRS). Results: All patients achieved radiological union at a mean duration of 16 weeks for type 5 and 17 weeks for type 6 however, full weight-bearing was allowed at a mean of 18 weeks (14 - 22 weeks). Functional results were excellent in 24 cases, good in 10 and poor in one. Most patients achieved functional range of motion at the knee joint (average flexion 1280 ) except one, who had a flexion of less than 1100 . One patient with a delayed union united after bone marrow injection. Other complications included pin tract infections in 9 cases, axial malalignment of less than 100 in 4 cases and a prominent screw in one. Conclusion: Percutaneous restoration of articular anatomy and a ring external fixation with or without minimal internal fixation is an excellent method of treatment in this group of fractures caused by high energy trauma and with a usual association of severe comminution and a poor soft tissue envelope.
