Peroneal tendon subluxation in a case of anomalous peroneus brevis muscle.
We report a case of peroneal tendon subluxation as a result of an anomalous extension of the peroneus brevis muscle into the fibular groove, causing an encroachment phenomenon, stretching-out of the superior peroneal retinaculum, longitudinal splitting of the peroneus brevis tendon, subluxation of the peroneal tendons, and peroneal tenosynovitis. We describe a simple surgical technique for tendon stabilization, after decompression of the fibular groove.
