Introduction

- The larger of the two terminal branches of thetibial nerve.

- accompanies the medial plantar artery.

- its origin under the "flexor retinaculum" it passes

deep into the muscles of the toes, and becomes the

"proper plantar digital nerve" to the great toe.

- . It finally divides opposite the bases of the toes

into the three "common digital nerves."


3/10

Distribution

The branches of the medial plantar nerve are:

(1) cutaneous

(2) muscular

(3) articular

(4) a proper digital nerve

to the medial side of thegreat toe,

(5) three common

digital nerves.

Introduction

- a branch of the tibia nerve, in turn a branch of

the sciatic nerve.

- supplies the skin of the fifth and lateral half of the

fourth toes, as well as most of the deep muscles of

the foot.

- its distribution can be compared to the ulnar nerve

in the hand.


5/10

Distribution

- The third common digital nerve receives a

communicating branch from the lateral plantar

nerve; the first gives a twig to the first Lumbricalis.

- Each proper digital nerve

gives off cutaneous and

articular filaments.- It passes obliquely forward

with the lateral plantar artery

to the lateral side of the foot.


6/10

Causes of Injury of Medial Plantar Nerve and Lateral

Plantar Nerve.

- Frequently seen as a sports injury, lateral plantar

nerve pain can be caused by fractures or repetitivestress injury.

- The most common pathology relates to external

compression from shoes that are too tight or to

plaster casts.

- Associations include posttraumatic fibrosis, tendon

sheath cysts, rheumatoid arthritis,

and hyperthyroidism.

Treatments of Medial Plantar Nerve and Lateral

Plantar Nerve.

-treated by wearing arch supports and taking non

steroid anti-inflammatory drugs (NSAID) likeibuprofen.

- Cases of Baxter's nerve pain which do not respond tothis treatment can be treated with surgery.


9/10

Physical exam of Medial Plantar Nerve and Lateral

Plantar Nerve.

- Injury to lateral/medial plantar nerve leads to weak

or absent MTP flexion (intrinsic minus).
