Objective

The aim of the study was to evaluate inter observer reliability and intra observer reproducibility between the three column classification using 3D CT reconstruction models and schatzker classification systems using 2D CT models.

Materials and methods

Fifty two consecutive patients with tibial plateau fractures were evaluated by two orthopaedic surgeons. All patients were classified into Schatzker and three column classification systems using CTimages. The Images were evaluated in a randomised and blind fashion. Demographics of the patient were blinded to reduce observer bias. The inter observer reliability was measured for both classfications in round one. In round two the process was repeated after two weeks and the intra observer reproducibility was measured using cohen kappa coefficient and level of agreement based on Landis and Koch.
