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. […]

Achilles Tendonitis, Achilles Tear and Achilles Rupture in Singapore

Achilles tendonitis is a condition of irritation and inflammation of the large tendon in the back of the ankle. Achilles tendonitis is a common injury that tends to occur in recreational athletes. Overuse of the Achilles tendon can cause inflammation that can lead to pain and swelling. Achilles tendonitis is differentiated from another common […]

Running and Ankle injury

Running is one of the easiest and most popular ways to stay fit. It is also one of the easiest ways to develop an injury. 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.

[…]

Passive dorsiflexion

Positioning.

The ankle is in neutral position with the heel resting on the couch. The knee is slightly flexed. The examiner is distal to the foot. He places one hand at the plantar aspect of the forefoot. The other hand is at the back of the heel.

Procedure..

Move the foot in the dorsal direction, […]

Palpation of the anterior talofibular ligament

The index finger is laid on the anterior surface of the lateral malleolus. A combined plantar flexion-inversion movement of the ankle makes the lateral process of the talus more prominent. The ligament is felt as a thin, flat and horizontal structure, pressing against the palpating finger.

Palpation of the sinus tarsi

Starting from the anterior surface of the lateral malleolus and moving anteriorly and medially, the finger falls into a depression – the sinus tarsi. If the finger is left in place and the foot is inverted, the depression excavates and its borders can be better ascertained. Just anterior to the malleolus the lateral process of […]

Osteochondritis Dissecans

Osteochondritis dissecans (OCD) is a localized separation of a segment of bone and cartilage from the surrounding, normal bone and cartilage. If the bony part of the fragment becomes necrotic (dead),there will be no healing and there will be a complete separation of the fragment from the surrounding tissue. In 75% of cases the lesion […]

Anterior Chronic Compartment Syndrome

SYMPTOMS

There is a gradual onset of diffuse exercise-induced pain on the anterior lateral aspect of the lower leg. It is common in fairly short but muscular ‘bulky’ athletes. The pain becomes so great that continued sport is not possible. The athletes complain that the muscles feel like they are bursting. Rest, with the […]

Tarsal Tunnel Syndrome

SYMPTOMS

There is aching or sharp pain around the medial part of the foot and ankle joint, often radiating along the medial or the lateral part of the foot, or towards the plantar fascia insertion.

AETIOLOGY

This syndrome is caused by trapping of the posterior tibia nerve or any of its branches in the tarsal […]
