The Internal Malleolar Artery is a small branch of the anterior tibial artery that supplies blood to the ankle joint. It is one of the key arteries involved in the vascular supply of the lower leg and foot.

Anatomy

The internal malleolar artery originates from the anterior tibial artery just above the level of the ankle joint. It travels downwards and medially to reach the medial malleolus, the bony prominence on the inner side of the ankle. Here, it gives off several small branches that supply the skin and deep tissues of the medial ankle region.

Clinical Significance

The internal malleolar artery is important in the clinical setting as its pulsations can be felt on the medial aspect of the ankle, providing a useful site for assessing the circulatory system in the lower limb. It is also significant in surgical procedures involving the ankle joint, as damage to this artery can lead to complications such as ischemia or necrosis.
