2019年10月31日 · The median nerve enters the palm beneath the flexor retinaculum and divides into three branches. The ulnar branch divides into two and supplies the 3rd web and adjacent sides of ring and middle fingers and the 2nd web and adjacent sides of middle and index fingers. The latter branch supplies the second lumbrical muscle.

Finger nerve repair currently has two main surgical approaches. End-to-end tension-free neurorrhaphy has traditionally been the preferred repair method in lesions with a gap smaller than 5 mm . When the nerve ends cannot be approximated without tension, nerve reconstruction becomes the most commonly used method. Various materials are available ...

Digital nerve blocks are traditionally placed in the web space adjacent to the metacarpal head, with 1 needle insertion on each side of the finger. The middle 3 fingers can be anesthetized by blocking only the palmar digital nerves of those fingers. The thumb and fifth digit are anesthetized by blocking both their palmar and dorsal digital nerves.

A common digital nerve laceration to the thumb will result in a sensory defect along the radial and ulnar aspects of the distal thumb, while a common digital nerve injury to the palm will present with a sensory deficit along the adjacent sides of the second or third web space (median nerve) or the fourth web space (ulnar nerve). 10

Digital nerve injuries, or nerve injuries to the finger, most commonly occur after a sharp laceration to the finger. In these scenarios, the laceration can transect the nerve, which results in loss of sensation. In each finger, there are two digital nerves that run on either side of the finger.

Digital nerve lesions are a common consequence of hand trauma, affecting sensation and function. Early diagnosis and operative management are crucial for maximizing recovery potential. 2.

2019年5月7日 · At the finger level, the digital nerves run volar to the digital arteries. Axons are cut though Schwann cells and surrounding nerve layers remain intact. Wallerian degeneration occurs distal to injury. Sharp injuries have smaller zones of injury. Crush injuries are associated with severe and diffuse tissue injury.

The radial digital nerve of the left index finger was missing with a 2.2-cm gap in zone 1 and zone 2 distal to the trifurcation. Discussion was held with the patient and his mother regarding different treatment options.

2022年9月29日 · There are 2 digital nerves in each of your fingers and thumb. They are positioned one on each side of the finger on the palm side of the hand. These nerves pass messages to your brain about what you can feel. They tell you when something is hot, cold, sharp, blunt, hard or soft.

-Fashion a short-arm dorsal blocking splint holding the wrist in neutral, MP joints of the injured fingers in 50 degrees of flexion, and IP joints in extension. -Wear splint full-time. -Starting at 3 weeks, gradually increase MP joint extension by 15 degrees weekly. -Splint can be converted to hand-based only at 4 weeks.
