Peroneal tenosynovitis: What are the signs?

Peroneal tenosynovitis is characterized by inflammation of the tendon and its cover which often occurs if the peroneal tendons are chafed or strained during repeated ankle movement. This usually occurs in sports-related running and jumping or if the individual endured acute ankle sprains. In addition, having a high arch can add up to the injury.

The peroneal muscles are positioned throughout the exterior of the lower region of the leg. The tendons move at the rear of the ankle bone to incorporate onto the foot to facilitate movements of plantar flexion such as pointing the toe or turning the sole outwards.

Lateral ankle pain typically occurs with injuries to the peroneal tendon particularly at the site where the tendon moves behind the ankle bone. Discomfort in the rear of the foot might be an indication of peroneal tenosynovitis.

The affected areas are usually tender during activity and palpation but generally the pain settles with rest. Take note that the ankle might feel rigid upon an extended period of inactivity.

Swelling

Since peroneal tenosynovitis is characterized as an inflammatory ailment, the swelling that occurs throughout the tendon is expected.

Take note that the swelling is likely to arise beneath and behind the lateral region of the ankle bone. Generalized swelling might be evident or felt along the tendon. If compared to the unaffected tendon, the damaged tendon often feels thicker.

Erratic ankle sensations

Individuals who suffer from peroneal tenosynovitis might feel a snapping or popping sensation in the ankle region on the affected side. The condition might lead to the weakening of the tendon that results to weakness or instability of the ankle.
