Interosseous membrane of forearm
Interosseous Membrane of Forearm
The Interosseous Membrane of Forearm (also known as the Antebrachial Membrane) is a thick, fibrous sheet that connects the two bones of the forearm, the radius and the ulna. It plays a crucial role in the stability of the forearm, as well as in the transmission of forces from the wrist to the elbow.
Anatomy
The interosseous membrane of the forearm extends from the proximal to the distal end of the forearm, between the interosseous margins of the radius and ulna. It is wider above than below, and its fibers are directed downward and medially.
Structure
The membrane is composed of dense, regular connective tissue. The fibers of the interosseous membrane are oriented obliquely from the radius to the ulna, forming a direction that is from lateral to medial and from proximal to distal.
Function
The interosseous membrane serves several important functions:
- Force Transmission: It helps to transmit axial loads from the hand and wrist to the humerus, bypassing the elbow joint.
- Stability: It provides stability to the forearm, preventing the radius and ulna from spreading apart.
- Muscle Attachment: It serves as a site of attachment for several muscles, including the flexor digitorum profundus and extensor pollicis longus.
Clinical Significance
Injuries to the interosseous membrane can lead to instability of the forearm, pain, and limited range of motion. Such injuries are often associated with fractures of the radius and ulna, and may require surgical intervention.
