What is the interosseous membrane of the forearm?

What is the interosseous membrane of the forearm?

The interosseous membrane (IOM) of the forearm is a stout ligamentous complex linking the radius to the ulna. The anatomy of this structure has been studied by various investigators. 1, 2, 3, 4, 5, 6, 7 The IOM reportedly consists of distal membranous, middle ligamentous, and proximal membranous portions.

Why do the bones in the forearm have an interosseous membrane?

Function. The interosseous membrane divides the forearm into anterior and posterior compartments, serves as a site of attachment for muscles of the forearm, and transfers loads placed on the forearm.

What type of syndesmosis the interosseous membrane of forearm is?

The interosseous membrane of the forearm is a fibrous sheet that connects the radius and the ulna. It is the main part of the radio-ulnar syndesmosis.

What is the function of the interosseous membrane?

One such structure, the interosseous membrane, is a fibrous tissue with an oblique orientation from the radius to the ulna. The membrane maintains the interosseous space between the radius and ulna through forearm rotation and actively transfers forces from the radius to the ulna.

What is the function of the interosseous membrane between ulna and radius?

Is radioulnar joint is syndesmosis joint?

Radioulnar syndesmosis is a slightly movable articulation of the forearm where the contiguous bony surfaces from radius and ulna are united by interosseous ligaments : the interrosseous membrane of forearm and the oblique cord.

Which joint actions are enabled by the radioulnar joint and the interosseous membrane?

The tract of the interosseous membrane is taut in pronation and loose in supination. It strengthens the dorsal capsule of the distal radioulnar joint. During pronation the tract protects the ulnar head in a sling. Its attachment at the triangular fibrocartilage influences the distal radioulnar joint.

Can you injure your interosseous membrane?

Injuries of the interosseous membrane (IOM) of the forearm are frequently unrecognized, difficult to treat, and can result in a devastating sequelae for the wrist and elbow.

What is the interosseous membrane and function?

What does the interosseous membrane do?

What type of joint is the interosseous membrane?

syndesmosis joint
The interosseous membrane is a thick dense fibrous sheet of connective tissue that spans the space between two bones forming a type of syndesmosis joint.

What is the interosseous membrane?

What joint is responsible for forearm pronation and supination?

proximal radioulnar joint
Pronation and supination are movements that occur at the proximal radioulnar joint. The head of the radius is discoid and fits with the radial neck within the circular annular ligament, that attaches the proximal radius to the ulna.

Where is interosseous membrane located?

forearm
Gross Anatomy The antebrachial interosseous membrane is a fibrous structure located in the midsubstance of the forearm. It lies between the radius and ulna and possesses distinct orientation and direction.

Where is an interosseous membrane joint found?

At a syndesmosis, the bones are more widely separated but are held together by a strap of fibrous connective tissue called a ligament or a wide sheet of connective tissue called an interosseous membrane. This type of fibrous joint is found between the shaft regions of the long bones in the forearm and in the leg.

Where are interosseous membranes?

In the upper limb, the interosseous membrane is between the radius and ulna. It divides the forearm into anterior and posterior compartments and also serves as an attachment for several deep muscles of the forearm and hand. In the lower limb, the interosseous membrane is between the tibia and fibula.

What movement occurs at the radioulnar joint?

pronation and supination
There are two movements possible at this joint; pronation and supination. Pronation: Produced by the pronator quadratus and pronator teres. Supination: Produced by the supinator and biceps brachii.
