Peroneal Tendon Injuries

Accuracy of MR findings in characterizing peroneal tendons disorders in comparison with surgery

“…PL tears usually start either at the tip of the lateral malleolus or at the peroneal process of the calcaneus, near the insertion of the inferior extensor retinaculum. The tear can extend distally to the cuboid groove (15). Degenerative chronic tears may also be caused by increased friction of the PL against either a hypertrophic peroneal tubercle or the cuboid bone as the tendon curves underneath it (4).…”

Anatomical Variations in the Insertion of the Peroneus (Fibularis) Longus Tendon

“…The peroneus longus tendon everts and aids in plantarflexion of the foot at the ankle and is responsible for pulling the base of the first metatarsal inferiorly, thereby counteracting the superior pull of the anterior tibial tendon. 19 It is also a stabilizer of both the longitudinal and transverse arches. These multiple functions of the peroneus longus tendon are due to the traversing of the tendon over several joints.…”

“…Several authors have reported superiority of the peroneus brevis over the peroneus longus in the ability to evert and abduct the foot. 14,19 The peroneus brevis tendon is commonly used in reconstruction of the ankle ligaments and the Achilles tendon. 2,12,17,18 When used as a donor for tendon transfer and ligament or tendon reconstruction, the brevis tendon is used either in part or full because function is thought not to be compromised by its sacrifice.…”

“…2,12,17,18 When used as a donor for tendon transfer and ligament or tendon reconstruction, the brevis tendon is used either in part or full because function is thought not to be compromised by its sacrifice. 19 In these instances, a thorough knowledge of the insertion of the only remaining evertor and abductor of the foot, the peroneus longus tendon, becomes even more relevant.…”

“…Tears of the peroneal tendons are not uncommon, and high tensile forces can cause acute avulsion fracture through the os peroneum or a longitudinal tear with fragmentation of the bone. 19 The peroneus longus tendon also has a greater role than any other structure in resisting varus force on the first metatarsal. Any partial or complete loss of stabilization of the first metatarsal bone by the peroneus longus tendon leads to metatarsus primus varus.…”
