A clinico-radiological study of bicondylar tibial plateau fractures managed with dual locking plates

Abstract

BackgroundTreatment of bicondylar intra-articular tibial plateau fractures due to high energy trauma is complex and highly prone to complications due to fracture patterns and extensive soft tissue damage. AimThe study's objective was to evaluate the clinical, radiological and functional outcome, including the complications in closed Schatzker type V and VI tibial plateau fractures managed with dual locking plates using less extensile approaches and indirect reduction techniques. Materials and methodsThirty-four patients of closed Schatzker Type V and VI treated with pre-contoured locking plates were evaluated clinically and radiologically. Dual plating was done using a less extensile anterolateral approach for lateral plate and medial/open posteromedial approach for medial plate. Functional results were evaluated using the Knee Society Score (KSS) and radiological results by the Modified Rasmussen score (MRS) for radiological assessment. ResultsThe mean age of patients in our study was 45 years (range = 26–60 years) with a male predominance of 84.4%. The average time difference between trauma and surgery was 7.6 days (range = 5–14 days) with an average length of hospital stay of 8.5 days (range = 7–18 days). Autologous bone grafting from the iliac crest was done in 10 patients (29.4%) with a sizeable metaphyseal void. The study has a mean follow-up period of 22.6 months. The complete union was seen at an average of 17.4 weeks. The average knee ROM at the last follow-up was 110.75°. Three patients had complications, 2 with wound dehiscence and 1 with deep infection. ConclusionInternal fixation with dual locking plates is biomechanically strong and stable and gives excellent to good functional outcomes. However, the timing of internal fixation is essential in such complex injuries to prevent soft tissue complications and failure. The use of rigid fixation by less extensile approaches and indirect reduction techniques helps prevent wound healing problems and allows early knee mobilization.
