peroneus brevis
fibularis brevis

This allows the peroneus brevis tendon to move untethered over the lateral malleolus, creating pain.

If, however, it enters the tarsometarsal joint, then it is an avulsion fracture caused by pull from the peroneus brevis.

It innervates the peroneus longus, peroneus brevis, and the short head of the biceps femoris muscles.

Its astragalus is almost triangular rather than primitive L-shape and it has pronounced process on fifth metatarsal for insertion of peroneus brevis.

The tendons of the peroneus longus and peroneus brevis course behind it on the way to their insertions on the foot.

The superficial peroneal nerve supplies the muscles of the lateral compartment of the leg namely: peroneus longus and peroneus brevis.

Peroneal group: peroneus longus arises on the proximal aspect of the fibula and peroneus brevis below it on the same bone.

The fibularis brevis muscle (or peroneus brevis) lies under cover of the fibularis longus, and is a shorter and smaller muscle.

In the Evans procedure, the peroneus brevis muscle is separated from its musculotendinous compound and its proximal end is sutured to the peroneus longus.

Origin: forepart of upper and lateral surface of calcaneus, in front of grove for peroneus brevis, from interosseous talocalcaneal ligament, stem of inferior extensor retinaculum.

Distally, peroneus longus crosses the plantar side of the foot to reach its insertion on the first tarsometatarsal joint, while peroneus brevis reaches the proximal part of the fifth metatarsal.

Renowned Athletic Trainer, Mark "Digger" Wagners ATC, is infamous for his controversial refusal to tape ankles citing massive hematomas to the Peroneus brevis and Peroneus longus.

Its chief anatomical significance is as a point of divergence of the previously common pathway shared by the distal tendons of peroneus longus and peroneus brevis en route to their distinct respective attachment sites.

The muscle arises from the lower third of the anterior surface of the fibula; from the lower part of the interosseous membrane; and from an intermuscular septum between it and the peroneus brevis muscle.

The Schilling tendon procedure is a temporary surgical procedure developed by the former Boston Red Sox team physician William Morgan, MD to stabilize the peroneus brevis tendon so that it is prevented from anterior displacement during ankle eversion.
