Abstract:
Objective:To compare the morphological variation of the fibular malleolar groove and fibrocartilaginous ridge injury in those with and without peroneal tendon dislocation using MRI.
Methods:Data of 45 patients (40 males, 5 females; average age 23.4±7.7 years, 11-44 years) with recurrent peroneal tendon dislocation treated from April 2010 to July 2017 and 45 patients (33 males, 12 females; average age 41.6±11.8 years, 17-67 years) without dislocation treated from June 2015 to Septem-ber 2017 were retrospectively analyzed. The morphological variation of the fibular malleolar groove and fibrocartilaginous ridge in-jury were compared between the two groups according to Rosenberg’s classification (convex, the posterior cortex of the fibula bulg-es outward; concave, the posterior fibular surface has a shallow-to-deep depression; flat, neither concavity nor convexity is found).
Results:In group of patients with recurrent peroneal tendon dislocation: concave, 10 patients (22.2%, 10/45); flat, 27 patients (60.0%, 27/45); convex, 8 patients (17.8%, 8/45); fibrocartilaginous ridge injury, 44 patients (97.8%, 44/45). In group of patients without peroneal tendon dislocation: concave, 16 patients (35.6%, 16/45); flat, 18 patients (40.0%, 18/45); convex,11 patients (24.4%, 11/45); fibrocartilaginous ridge injury, 13 patients (28.9%, 13/45).
Conclusion:According the results, significant differ-ence has not been found in morphologic variations of the fibular malleolar groove between patients with and without recurrent pero-neal tendon dislocation. Fibrocartilaginous ridge injury is common in MRI of patients with recurrent peroneal tendon dislocation.
