Understanding plain radiograph in association with 3-dimensional (3D) morphology of the ankle is essential for treatment about varus ankle osteoarthritis (OA). The aims of this study were to investigate whether the alignment of the tibial plafond as determined on plain radiograph reflected the alignment of the tibial plafond on computed tomography (CT) in varus ankle OA and whether the alignment of the tibial plafond changed as the OA progressed. The 3D CT and plain radiographs from 101 ankles with varus ankle OA were analyzed and compared with 40 ankles in control group. The tibial plafond was assessed in the coronal and sagittal planes using 3D CT. The medial angle between the vertical line and the tibial plafond was measured on 3 different coronal plane CT images which was anterior, middle and posterior area of the tibial plafond. The medial distal tibial angle on plain radiograph reflected the posterior area of the tibial plafond on CT. The amount of varus angulation on CT was larger in anterior and middle area of the tibial plafond than the posterior area. There was a difference in the degree of varus of the tibial plafond between control group and OA patients; however, there was no difference among patients in different stages of varus ankle OA. Weightbearing plain radiographs underestimate the varus deformity in anterior and middle area of the tibial plafond and there is no significant difference in deformity of the tibial plafond among patients in different stages of varus ankle OA.

Introduction: With the increased use of CTs in cases with trimalleolar ankle fractures, bone fragments between the posterior malleolus and the rest of the articular surface tibial plafond surface - described as intercalary fragments (ICFs) - can be recognized. The aim of this study was to determine the ICF size threshold for a significant change in the pressure distribution at the ankle joint, having a considerable impact on the remaining cartilage of the joint.
Design And Methods: Eight human cadaveric lower legs were used, and a posterior malleolus Bartonicek II fracture was created with sequential 2mm, 4mm, 6mm and 8mm ICFs.

Introduction: There is evidence that the presence of a posterior malleolus fracture (PMF) worsens the prognosis of ankle fractures, making conservative treatment a poor choice. PMFs include a heterogeneous group of bone injury patterns that are sometimes associated to medial malleolus extensions, as well as fibula fractures or syndesmotic damage. This requires the surgeon to be well-versed in anatomy to choose the appropriate surgical approach.

Methods: Design: Retrospective review.
Setting: Level 1 Trauma Center.

Purpose: The purpose of this study was to determine the effects of medial opening low tibial osteotomy (LTO) on lower limb alignment, including the knee joint, 1 year after low tibial osteotomy.
Methods: This study included 20 legs of 20 patients (mean age, 66.8 ± 5.
