Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

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 short...

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 of the...

Published on: April 5, 2024

Area of Science:

Orthopedic Surgery
Traumatology
Anatomy

Background:

Carpal dislocations typically result from high-energy axial loading of the wrist.
Perilunate dislocations, a spectrum of carpal instability, were first described by Mayfield.
Carpal instabilities are classified as dissociative (within a carpal row) or non-dissociative (between carpal rows).

Purpose of the Study:

To report a rare case of complex carpal injury.
To describe a non-dissociative dislocation involving the entire proximal carpal row volarly.
To highlight a previously unreported variant of high-energy wrist injury.

Main Methods:

Case report of a patient with a complex carpal injury.
Radiographic and clinical evaluation of the carpal dislocation.
Review of existing literature on carpal dislocations and instabilities.

Main Results:

The patient presented with a non-dissociative dislocation of the entire proximal carpal row volarly.
This specific pattern of dislocation has not been previously reported in the literature.
The injury occurred secondary to high-energy axial loading of the forearm.

Conclusions:

Complex carpal dislocations represent a spectrum of injuries following high-energy trauma.
This case presents a unique variant of proximal carpal row dislocation.
Understanding these rare variants is crucial for accurate diagnosis and treatment of wrist injuries.
