We recommend the use of the peroneus longus muscle tendon unit based on an independent perforator from the peroneal artery.
Subcutaneous tendon rupture of the peroneus longus tendon could be caused by direct and indirect trauma to the foot, such as extreme inversion, plantar or dorsal flexion of the foot associated with contraction of the peroneus longus muscle in sports activities.
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.
