【 摘 要 】

Category:HindfootIntroduction/Purpose:The sublatar joint is formed by the articulation of the talus and the calcaneus. The Calcaneus had three facets; posterior, middle and anterior that articulate with the talus. The anterior facet is also continuous with the Talonavicular joint.Plain radiography of the foot and ankle is the usual method to detect degeneration in these joints, however plain films do not permit full characterisation of non-ossified structures, such as articular cartilage, marrow tissue and synovial fluid. MRI is a better way to detect these changes.The aim of this study was to develop a quantitative way to score arthritic changes to the subtalar and talonavicular joints using MRI that was usable, repeatable and reliable.Methods:The MRI scans of thirty consecutive subjects with foot and ankle pain were retrospectively evaluated. MRI images were obtained using 1.5-T MRI. Images were interpreted independently by three musculoskeletal radiologists. In order to determine intra-observer reliabi...
