Abstract:
Arthroereisis is a rare and disputed procedure, where an implant screw is inserted into the sinus tarsi to treat flatfoot deformity. Weight-bearing radiographs are the most essential examinations to assess the correct localization and related measurements. Hardware loosening is the most common complication seen as localized lucency and as dislocation of the implant. Computed tomography yields superior resolution with reconstruction capabilities. On magnetic resonance imaging, the implant appears as a dark signal focus on T1 and T2-weighted images with a hyperintense T2-signal rim. As the data on the imaging of arthroereisis are scarce, we aimed here to review the typical imaging findings.
