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,...

Muscles that Move the Forearm

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Summary

This summary is machine-generated.

Perforator-based forearm flaps offer a single-stage solution for severe hand soft tissue defects, preserving function and the main artery. This technique effectively treated thumb contracture post-burns.

Area of Science:

Plastic Surgery
Hand Surgery
Burn Reconstruction

Background:

Reconstructing hand soft tissue defects with exposed vital structures (tendons, nerves, joints, bones) presents significant surgical challenges.
Adequate tissue coverage is crucial for preserving hand function after trauma or burns.

Observation:

A patient with a right thumb adduction contracture resulting from second-degree burns was treated.
The treatment involved the use of a perforator-based forearm flap.

Findings:

The perforator-based forearm flap utilizes 5 to 11 perforating branches from the radial artery, located proximally to the radial styloid.
This single-stage technique is suitable for emergency conditions and spares the main radial artery.

Implications:

This method provides a viable option for complex hand reconstructions, potentially improving functional outcomes.
While effective, the cosmetic outcome at the donor site is a noted disadvantage requiring consideration.
