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...

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...

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...

Area of Science:

Orthopedic Surgery
Hand and Wrist Surgery
Sports Medicine

Background:

Intercarpal ligament injuries, including scapholunate and lunotriquetral tears, are frequent causes of wrist pain.
Despite numerous surgical techniques, optimal management for subacute/chronic injuries without articular wear remains debated.
Traditional methods like ligament tenodesis have shown inconsistent outcomes.

Purpose of the Study:

To evaluate a novel all-dorsal reconstructive technique for intercarpal ligament injuries.
To assess the efficacy and predictability of the Arthrex InternalBrace system in wrist reconstruction.
To establish a preferred surgical approach for chronic wrist pain due to ligamentous instability.

Main Methods:

Investigation of a novel all-dorsal reconstructive technique utilizing the Arthrex InternalBrace system.
Performance of over 20 procedures using this technique since 2019.
Focus on subacute and chronic intercarpal ligament injuries without articular wear.

Main Results:

Achieved predictable carpal stabilization in all patients.
Reported significant pain relief and restoration of wrist motion.
Average tourniquet time was under 60 minutes.

Conclusions:

The all-dorsal InternalBrace technique provides a reliable and efficient solution for intercarpal ligament injuries.
This approach simplifies reconstruction compared to traditional methods, offering consistent positive outcomes.
It is now the senior author's primary reconstructive method for these wrist conditions.
