Peroneal Tendon Instability , A Rare But Important Ankle Injury

Peroneal Tendon Instability

Ankle sprain is a common injury in Singapore athletes as well as the active adult. Most of the time, the ankle heals with a little care (rest, taping, ice). But one rare complication of lateral ankle sprains is a condition called peroneal tendon instability. A lateral ankle sprain means the side of the ankle away from the other leg is sprained. The two peroneal tendons go down the leg and around the back of the ankle bone. The tendons set down inside a tunnel formed by bone and connective tissue called the retromalleolar groove. A fibrous band (the superior peroneal retinaculum) goes across the tendon to hold them in the groove. […]

Running injuries are common and often effect the hips, knees, ankles, and feet of runners. The impact and stress of running is sometimes hard on the muscles and joints; especially […]

Strong varus movement at the ankle

Significance.

This movement tests the integrity of the strong distal tibiofibular ligaments.

Positioning.

The ankle is in neutral position and the knee extended. The examiner is distal to the foot. The ipSilateral hand fixes the leg at the inner side, just above the ankle. The contralateral hand grasps the foot at the heel.

Procedure.

[…]

Combined dorsiflexion-eversion

Significance.

This is a specific test to demonstrate anterior periostitis of the fibula.

Positioning.

The knee is slightly flexed and the ankle in neutral position. The examiner is distal to the foot. His ipsilateral hand supports the heel and the contralateral hand is placed against the plantar and lateral side of the foot. […]

Anterior drawer test

Significance.

This is a specific test for the integrity of the anterior talofibular ligament.

Positioning.

The subject lies supine and relaxed with the knee Aexed to 90°. The heel rests on the couch and the foot is in slight plantar flexion. The examiner stands at the opposite side of the foot, level with it. […]

Combined plantar flexion-eversion

Significance.

This movement stretches all the medial ligaments of the ankle.

Positioning.

The heel rests on the couch, the knee is slightly Aexed and the ankle is in neutral position. The examiner is distal to the foot. His contralateral hand fixes the leg at the distal and lateral side. The ipSilateral hand encircles the […]
