Inferior calcaneal nerve

Last revised by Henry Knipe on 21 Dec 2021

The inferior calcaneal nerve (or Baxter nerve) is a mixed nerve in the foot. 

Originates from the lateral plantar nerve at the level of the medial malleolus.

Courses between the abductor hallucis muscle and the quadratus plantae and along the medial border of the long plantar ligament. It then turns laterally to send out motor branches to the abductor digiti quinti muscle.

It sends out small motor branches to the following muscles

It also sends sensory fibers to the long plantar ligament and calcaneal periosteum.

It also gives rise to a sensory branch for the anterior calcaneal tubercle.
