Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Arteries of the Upper Limbs

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Summary

This summary is machine-generated.

Lunate dislocation, a rare injury from high-energy trauma, can cause median nerve compression. This volar bone displacement is an uncommon cause of carpal tunnel entrapment neuropathy.

Area of Science:

Orthopedic Surgery
Traumatology
Neurology

Background:

Lunate dislocation is an infrequent injury typically seen in young adults.
It often results from significant, high-energy trauma to the wrist.
Volar displacement of the lunate bone is a key characteristic of this injury.

Purpose of the Study:

To describe the mechanism and consequences of lunate dislocation.
To highlight the potential for median nerve compression within the carpal tunnel.
To underscore its role as an uncommon cause of entrapment neuropathy.

Main Methods:

Review of existing literature on lunate dislocations.
Analysis of case studies involving high-energy wrist trauma.
Correlation of radiographic findings with clinical presentation of nerve compression.

Main Results:

Volar displacement of the lunate bone was consistently observed.
Median nerve compression within the carpal tunnel was a noted complication.
Entrapment neuropathy was identified as an infrequent but significant outcome.

Conclusions:

Lunate dislocation is a serious wrist injury requiring prompt diagnosis and management.
The volar displacement poses a risk of secondary median nerve compromise.
Early recognition is crucial to prevent long-term neurological deficits.
