We recommend the use of the peroneus longus muscle tendon unit based on an independent perforator from the peroneal artery.
An overly tight tendon of the peroneus longus muscle is typical of the rigid pes cavus foot type, and easily locks the first ray down into plantar flexion, making the foot even more rigid and shifting weight onto the lateral arch.65 In dance, this leads to poor technique, especially landings in demi-plie that lack shock absorption.
These include all the usual suspects prone to injury in runners: the Achilles tendon, the iliotibial band, the plantar arch and the peroneus longus muscle, which runs down the outer shin to the sole of the foot.
Gabison and Gentile (22) describe a case of acute foot drop after ankle sprain, in which the peroneus longus muscle was ruptured.
