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. […]

Palpation of the peronei

About one finger-breadth under and slightly anterior to the lateral malleolus, a bony notch can be palpated: the trochlear process . Since this prominence is situated between both peroneal tendons, the palpating finger will be lifted off by the hardening tendons when an eversion movement is performed. The peroneus longus is plantar and the peroneus […]

Ankle Sprain

Basics Description Acute sprains of the lateral ligaments about the ankle are the most common injury in sports and also occur commonly in the general population. Most commonly a partial tear or complete rupture of the ATFL occurs. More severe injuries include the CFL . Lateral ankle sprain results from an inversion mechanism. Classification […]

Ankle Instability

Basics Description Recurrent ankle sprains occurring primarily from an inversion stress on a plantarflexed ankle, which lead to chronic ankle pain and instability Divided into 2 types: Functional instability: Pain causes ankle to be unstable. Feeling of ankle giving way Neuromuscular deficit True mechanical instability: Frank insufficiency of ligaments Physiologic ROM is exceeded. Positive […]

A Patient’s Guide to Peroneal Tendon Subluxation

Introduction

The peroneals are two muscles and their tendons that attach along the outer edge of the lower leg. The peroneal tendons are enclosed in a fibrous tunnel that runs behind the outside ankle bone (the lateral malleolus). Damage or injury to the structures that form and support this tunnel may lead to a condition […]

A Patient’s Guide to Peroneal Tendon Problems

Introduction

Problems affecting the two peroneal tendons that lie behind the outer ankle bone (the lateral malleolus) are common in athletes. These problems mainly occur in the area where the two tendons glide within a fibrous tunnel behind the lateral malleolus.
