Tibialis Anterior Muscle is a key muscle in the anatomy of the lower leg, playing a crucial role in foot and ankle movement. It is situated on the front part of the leg.

Anatomy

The Tibialis Anterior Muscle originates from the lateral condyle and upper two-thirds of the lateral surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. It is innervated by the deep peroneal nerve (L4, L5), and its blood supply comes from the anterior tibial artery.

Function

The primary function of the Tibialis Anterior Muscle is dorsiflexion and inversion of the foot. This action is essential for activities such as walking, running, and climbing, where lifting the foot is necessary to clear the ground. It also plays a role in maintaining medial longitudinal arch of the foot.

Clinical Significance

Injury to the Tibialis Anterior Muscle can result from overuse, trauma, or compartment syndrome. Symptoms may include pain, swelling, and weakness in dorsiflexion of the foot, leading to a gait disturbance known as "foot drop." Treatment options vary from rest and physical therapy to surgical intervention in severe cases.

Rehabilitation

Rehabilitation exercises for the Tibialis Anterior Muscle include stretching and strengthening exercises aimed at restoring function and flexibility. Toe taps, heel walks, and resistance band exercises are commonly prescribed.
