[Injuries of the peroneal tendons : Often overlooked].

CLINICAL ISSUE: Injuries of the peroneal tendons are rare and often overlooked. Typical pathologies are tendinitis, tears and dislocation. Accompanying injuries are fractures. They are often associated with instability in the ankle and rearfoot deformities; therefore, these pathologies should be excluded or taken into consideration in the treatment. The clinical examination is crucial for the diagnosis.

DIAGNOSTIC WORK-UP: Ultrasound and magnetic resonance imaging (MRI) examinations are very helpful; however, the true extent of the tendon pathology is often first seen during surgery. Bony injuries and deformities are assessed radiographically and by computed tomography (CT).

PERFORMANCE: Although conservative treatment is generally used at the beginning of therapy, progression is more likely to occur in the case of tears; therefore, the correct timing for an operative therapy should not be missed. Dislocations are the domain of operative therapy. Acute tendinitis, on the other hand, is usually accessible to conservative therapy if it is not the result of a gross deformity.

ACHIEVEMENTS: Rehabilitation after operative treatment is demanding and prolonged especially after operative therapy of peroneal tendon tears. The results to be expected appear promising.
