A longitudinal tear of the peroneus brevis tendon is visible, extending from the level of the lateral malleolus, giving the tendon a C-shaped appearance, with its fibers surrounding the peroneus longus tendon. Tenosynovitis in the peroneal tendon sheath is also present.
Case Discussion
A longitudinal (split) tear of the peroneus brevis tendon may be a result of acute trauma, but may also be degenerative in nature, as in this case. Tenosynovitis is present in approximately half of the cases.
