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. […]

Hernia

Inguinal and femoral hernias are not uncommon and can be symptomatic producing radiating pain diffusely in the groin area. In athletes with persistent pain, ‘sports hernia’ can be a cause of problems: this is a syndrome of weakness of the posterior inguinal wall causing chronic groin pain, but without a clinically recognizable hernia.

Lateral Ankle Ligament Ruptures

SYMPTOMS

The patient refers to a sudden sharp tearing pain around the lateral aspect of the ankle joint after an acute inversion sprain or, on occasions, of recurrent instability after previous sprains.

AETIOLOGY

The anterior talo-fibular (ATF) and fibulo-calcanear (FC) ligaments are the most commonly damaged structures in uncomplicated inversion-plantar flexion ankle sprain. Most […]

Osteochondral Defect of the Talus

Basics Description OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. The most common sites are the posteromedial (53%) and anterolateral talar dome. Most classification systems are based on […]

Femoral Neck Fracture

Basics Description Femoral neck fracture is the most common cause of a broken hip. The femoral neck is the intracapsular portion of the proximal femur between the femoral head and the lesser and greater trochanters. Femoral neck fractures are most common in elderly patients, although younger patients involved in high-energy trauma also are affected. […]
