Calcaneal nerve branches

The plantar nerves. (Calcaneal branches labeled at bottom center.)

The Calcaneal Nerve Branches are a part of the Peripheral Nervous System that innervate the heel of the foot. They are derived from the Medial Plantar Nerve and the Lateral Plantar Nerve, which are branches of the Tibial Nerve.

Anatomy

The Calcaneal Nerve Branches are small nerves that provide sensory innervation to the skin of the heel. They are formed by the division of the Medial and Lateral Plantar Nerves, which are themselves branches of the Tibial Nerve, a part of the Sciatic Nerve.

The Medial Calcaneal Branches arise from the Medial Plantar Nerve and pass posteriorly to supply the medial aspect of the heel. The Lateral Calcaneal Branches, derived from the Lateral Plantar Nerve, innervate the lateral aspect of the heel.

Clinical Significance

Damage to the Calcaneal Nerve Branches can result in loss of sensation in the heel, which can lead to injuries such as heel spurs and plantar fasciitis. In addition, conditions such as tarsal tunnel syndrome can compress these nerves, leading to pain and numbness in the heel.
