Kaiser P, et al. - Researchers retrospectively correlated the kinematic dynamic rotation MRI (DR-MRI) of the wrist for assessment of extensor carpi ulnaris (ECU) tendon subluxation and dislocation. For this analysis, the presence of an ECU tendon subluxation or dislocation on the DR-MRI report was correlated to findings of the surgical report. The results obtained from the study indicate that DR-MRI was a feasible method to visualize ECU tendon subluxation and dislocation. Findings suggested that DR-MRI could distinguish between ECU tendon subluxation and dislocation.
