As opposed to the tibialis posterior tendon that runs inside the ankle, there are two peroneal tendons that run side-by-side behind the outer ankle bone. The peroneal brevis tendon attaches to the outer part of the fifth metatarsal at the middle of the foot, and the peroneal longus tendon runs under the foot and attaches near the inside of the arch. The main function of the peroneal tendons is to stabilize the foot and ankle and protect them from sprains.

 

Peroneal tendon injuries most commonly occur in individuals who participate in sports that involve repetitive ankle motion, and those with higher arches. Tendonitis and tendonosis (degenerative tears) are usually due to overuse, whereas acute tears can be caused by a traumatic event. Subluxation is when one or both tendons have slipped out of their normal position. It can be due to a variation in the shape of the bone or muscle that a person is born with, or it occurs following a trauma (such as an ankle sprain). Damage or injury to the tissues that stabilize the tendons (retinaculum) can lead to chronic tendon subluxation. As in all peroneal tendon injuries, symptoms of a subluxating tendon include: pain, swelling, warmth, and weakness or instability of the ankle. What sets subluxation apart from other peroneal injuries is a snapping feeling of the tendon around the ankle bone. Early treatment of a subluxation is critical, since a tendon that continues to sublux is more likely to tear or rupture.

Radiographs or an MRI may be needed to fully evaluate the ankle. Treatment options depend on the type of peroneal tendon injury that Dr. Mendoza diagnoses: immobilization, anti-inflammatories, RICE, bracing, and surgery to repair the tendon or tendons are all options.

A plantar fibroma is a benign nodule that grows on the bottom of the foot that usually appears in adults.  It is typically slow growing and measures less than an inch in size. More invasive, rapid-growing and multiplanar fibromas are considered plantar fibromatosis. Both are benign tumors made up of cells found in ligaments called fibrocytes. Fibromas can also occur in the palmar fascia of the hands – often called trigger finger.

Symptoms consist of a painful mass on the bottom of the foot, roughly in the middle of the arch. The mass may be painful with pressure or shoe wear.  The cause is unknown but is thought to have a genetic component. Trauma to the foot does not seem to be a factor. As opposed to plantar warts, plantar fibromas reside in the deep fascia of the foot between the skin and the first (superficial) layers of muscle. Asymptomatic fibromas may be left untreated, whereas painful fibromas may be treated with an off-loading insole, anti-inflammatory injection, or surgical excision as a last resort.
