What are digital nerves?
Digital nerves are nerves that travel from the palm to the tips of the fingers and thumb. They can be damaged by pressure, stretching or cutting.
What is dorsal digital expansion?
The term dorsal digital expansion refers to the small triangular aponeurosis covering the dorsum of the proximal phalanx with its base at the metacarpophalangeal joint.

Nerve entrapment may cause a shooting, burning pain, or sensitivity on the top of the foot.
What causes lateral plantar nerve pain?
Medial and lateral plantar nerve entrapment is compression of nerve branches at the inner heel (the medial or lateral branches of the plantar nerve) that causes pain. The nerve branches are pinched (compressed) between bone, ligaments, and other connective tissues, causing pain.
What is a plantar common digital nerve?
The common plantar digital nerves of medial plantar nerve are nerves of the foot. The three common digital nerves (nn. digitales plantares communes) pass between the divisions of the plantar aponeurosis, and each splits into two proper digital nerves: Those of the first common digital nerve supply the adjacent sides of the great and second toes;
How many nerves in feet?
