Muscle herniation of the extremities: Two case report

Abstract

Muscle herniation of the extremity is a rare clinical entity. Here, we report two patients with muscle herniation at different locations. The first case is a 52-year-old man complained of pain, a local mass, and paresthesia on his right cruise, especially occurring during prolonged exercise. He had medical history including accidentally cut his cruris with the saw two years ago, fortunately he had no tibial fracture. A symptomatic posttraumatic herniation of peroneus longus muscle was diagnosed. The fascial defect was treated surgically. The second case is a 14-year-old child. He had suffered a Type 1 open radius ulna shaft fracture ten years ago. An asymptomatic posttraumatic muscle herniation at the flexor muscles of the forearm was diagnosed. His medical history included the closed reduction and cast application for fractures and close follow-up. As he had no pain or dysfunction and positive findings in ultrasonography and magnetic resonance imaging at the presentation, no treatment was applied. Muscle herniation of the extremity is a rare clinical entity. It was asymptomatic, so it needs no treatment. If it were symptomatic, a longitudinal fasciotomy may be a choice for surgical treatment.
