Dorsal digital nerves of the foot.

The Dorsal Digital Nerves of Foot are a group of nerves in the human foot that provide sensory innervation to the skin on the dorsal aspect of the toes. They are branches of the dorsal cutaneous nerve, which is itself a branch of the superficial fibular nerve.

Anatomy

The dorsal digital nerves of the foot originate from the dorsal cutaneous nerve, which is a branch of the superficial fibular nerve. The superficial fibular nerve is one of the five terminal branches of the common fibular nerve, which is a major nerve of the lower limb.

The dorsal digital nerves of the foot divide into two branches. The medial branch provides sensory innervation to the medial half of the big toe and the lateral half of the second toe. The lateral branch provides sensory innervation to the lateral half of the fourth toe and the medial half of the fifth toe.

Clinical significance

Damage to the dorsal digital nerves of the foot can result in a loss of sensation in the affected areas of the toes. This can occur as a result of injury, surgery, or conditions such as diabetes or peripheral neuropathy.
