The abductor digiti minimi muscle of the foot (Latin: musculus abductor digiti minimi pedis) is a muscle located on the lateral side of the foot. It is one of the muscles in the first layer of the sole of the foot.

Structure

The abductor digiti minimi muscle originates from the calcaneus and the plantar aponeurosis. It inserts into the lateral side of the base of the proximal phalanx of the fifth toe.

Innervation

The muscle is innervated by the lateral plantar nerve, which is a branch of the tibial nerve.

Blood Supply

The blood supply to the abductor digiti minimi muscle is provided by the lateral plantar artery.

Function

The primary function of the abductor digiti minimi muscle is to abduct and flex the fifth toe. This action helps to maintain balance and stability while walking and standing.

Clinical Significance

Injury or dysfunction of the abductor digiti minimi muscle can lead to difficulties in walking and maintaining balance. Conditions such as plantar fasciitis or nerve damage can affect the performance of this muscle.
