Ankle and Foot Conditions

Peroneal tendon pathology is far more common then reported.  Tendon pathology can range from tenosynovitis, low riding peroneal muscle, tendonosis, tendon tear (split) and peroneal tendon subluxation. Much of peroneal tendons pathology is rarely isolated, but in conjunction with ankle instability or varus deformities: cavus, calcaneal varus and/or ankle varus.
Peroneus quatrus muscle	Tenosynovitis is the yellowish tissue around the tendons	Intra-tendinous ganglion
Prior to eversion	Tendons are subluxing anteriorly due to insufficient superior retinaculum	MRI shows that the osteochondral lip and retinaculum are insufficient showing fluid all along the anterior half of the fibula
Small tear	Large tear which also is subluxating	Multi-focal tear
