25 year old female with MRI findings of subtalar joint coalition. Assess middle facet coalition versus trauma from old fracture.IMAGE ACQUISITIONS: CT examination of the right foot, noncontrast Again seen is the abnormal articulation of the middle facet of the subtalar joint. The middle facet is more vertically oriented than normal with mild atrophy of the sustentaculum. Additionally, there is slight subchondral sclerosis and cyst formation at this joint. It is unclear whether these findings are secondary to fibrous coalition or prior trauma.Small ossicles are again seen distal to the lateral and medial malleoli, compatible with post traumatic sequelae. Please refer to report for recent MRI for further evaluation of soft tissue pathology.
Reidentification of the abnormal articulation at the medial facet of the subtalar joint which again may be secondary to old trauma versus fibrous coalition.
