A low-lying peroneus brevis muscle belly is a rare congenital anomaly that predisposes to peroneus brevis tendon tears and superior peroneal retinaculum injury with results peroneal tendon subluxation. This condition is defined by the extension of the muscle belly to the level of the fibular groove 1-3.
