Peroneal Tendon Dislocation/Dysfunction
Arch - The arch of the foot is the area of the bottom of the foot between the heel pad and toe pad.
Acrokeratosis verruciformis - a hereditary dermatosis characterized by the presence of numerous flat wart-like papules on the dorsal aspect of the hand, foot, elbow, and knee.
Ankle - the part of the leg just above the foot; the joint between the leg and the foot. It is a hinge joint formed by the junction of the tibia and fibula with the talus, or ankle bone. The bones are cushioned by cartilage and connected by a number of ligaments, tendons, and muscles that strengthen the joint and enable it to be moved. Because it is in almost constant use, the ankle is particularly susceptible to injuries, such as sprain and fracture. It is also often one of the first joints to be affected by arthritis or gout.
Ankle clonus - a series of abnormal reflex movements of the foot, induced by sudden dorsiflexion, causing alternate contraction and relaxation of the triceps surae muscle.
Athlete's foot - a fungal infection of the skin of the foot; called also tinea pedis. It causes itching and often blisters and cracks, usually between the toes. Causative agents are Candida albicans, Epidermophyton floccosum, and species of Trichophyton, which thrive on warmth and dampness. If not arrested, it can cause a rash and itching in other parts of the body as well. It is likely to be recurrent, since the fungus survives under the toenails and reappears when conditions are favorable. Although Athlete''s foot is usually little more than an uncomfortable nuisance, its open sores provide excellent sites for more serious infections. Early treatment and health care supervision insure correct diagnosis and prevention of complications. Specific diagnosis is made by microscopic examination or culture of skin scrapings for the fungus.
Peroneal tendons are two tendons that support two important foot muscles (peroneus brevis and peroneus longus) that originate on the outside of the calves. These two muscles allow you to roll to the outside of the foot while standing.
Peroneal tendons are also called stirrup tendons because they help hold up the arch of the foot. The two muscles are held in place by a band of tissue, called the peroneal retinaculum. Injury to the retinaculum can cause this tissue to stretch or tear. When this happens, the peroneal tendons can dislocate from their groove on the back of the fibula. The tendons can be seen to roll over the outside of the fibula, which damages the tendons.
Skiing, football, basketball, and soccer are the most common sports activities leading to peroneal tendon dislocation. In some cases, ankle sprains have also caused this condition. Patients usually have to use crutches after such an injury, in order to allow the retinaculum tissue to heal and the tendons to move back to their natural position on the fibula. Sometimes a splint or compression bandage is applied to decrease swelling. Anti-inflammatory medications and ice are often part of the treatment. Note: Please consult your physician before taking any medications.
In moderate to severe cases of injury, when the peroneal retinaculum is torn or severely stretched and susceptible to dislocation, surgery may be required.
