Tibialis anterior muscle herniation developed after trauma

Tibialis anterior muscle herniation in adolescents: A case series and review of the literature

“…Muscle herniations result from fascial defects allowing muscle fibers to protrude into the subcutaneous tissues . They are common in the lower extremity due to increased intracompartmental pressure from standing .…”

“…Constitutional herniations are often bilateral, occurring at natural weak points where neurovascular bundles pierce the fascia . Traumatic herniations result from penetrating trauma causing a tear or puncture in fascia or repetitive blunt trauma, overuse, or increased compartment pressure creating weakness in fascia over time . Entrapment of the herniated muscle is rare, but compression of nerves and vessels can occur …”

“…Muscle herniations result from fascial defects allowing muscle fibers to protrude into the subcutaneous tissues. 2,10 They are common in the lower extremity due to increased intracompartmental pressure from standing. 2,5,6 The anterior tibialis is often involved as its fascia is vulnerable to trauma; however, herniation can occur in other lower extremity muscles such as the extensor digitorum longus, fibularis longus, and fibularis brevis ( Figure 3).…”

“…2,7,10,11 Traumatic herniations result from penetrating trauma causing a tear or puncture in fascia or repetitive blunt trauma, overuse, or increased compartment pressure creating weakness in fascia over time. 5,10 Entrapment of the herniated muscle is rare, but compression of nerves and vessels can occur. 2,[5][6][7] Patients present with a subcutaneous nodule of the lower extremity that changes in size with position or after exertion.…”

An Interesting Case of Post Traumatic Tibialis Anterior Muscle Herniation

“…Most of the cases are small in size and described in athletes and young adults requiring excessive strain on legs. 3,4 Because of superficial and tight fascial compartment, anterolateral tibial compartment is the commonest site affected by muscle herniation.…”
