What is the interosseous membrane of the leg?

What is the interosseous membrane of the leg?

The interosseous membrane of the leg (middle tibiofibular ligament) extends between the interosseous crests of the tibia and fibula, helps stabilize the Tib-Fib relationship and separates the muscles on the front from those on the back of the leg.

What is the purpose of the interosseous membrane of the leg?

The interosseous membrane is located both in the forearm and also the lower leg. It is a structure that has ligamentous characteristics. The membrane provides stability for the radius and ulna and for the tibia and fibula.

Where is interosseous membrane found?

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.

Is the interosseous membrane a ligament?

Purpose: The interosseous membrane (IOM) of the forearm is a stout ligamentous complex that reportedly comprises several ligamentous components.

What is Tibiofibular Synostosis?

Tibiofibular synostosis is a rare condition of union between tibia and fibula. Etiologically, it may be congenital, acquired (traumatic, iatrogenic, therapeutic types) or idiopathic [8].

What is the interosseous nerve?

Introduction. Anterior Interosseous Nerve (AIN) is a motor branch from the Median nerve and runs deep in the forearm along with the anterior interosseous artery. It innervates three muscles in the forearm; an isolated palsy of these muscles is known as AIN Syndrome.

What is the squeeze test?

Squeeze test is another test to identify a tibiofibular syndesmosis. It is also a pain provocation test. The patient is in a supine position while the clinician grasps the leg of the patient, midway of the calf muscle on the affected limb, and perform compression with both hands.

What is the interosseous membrane made of?

connective tissue
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. In the upper limb, the interosseous membrane is between the radius and ulna.

Why is interosseous membrane important?

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.

Can you tear your interosseous membrane?

Severe forearm injuries involving separation of the radius and ulna may be due to rupture of the interosseous membrane. Rupture can lead to proximal migration of the radius and an apparent lengthening of the ulna at the wrist. Often interosseous membrane tears are associated with adverse impacts on forearm rotation.

Is the interosseous membrane of the leg ossified?

Ossification of the interosseous membrane (OIM) of the leg may exhibit some features similar to those of myositis ossificans. We report a case of OIM of the leg in a semiprofessional football player and analyse the different imaging, clinical, and pathogenetic features of the various types of this condition observed in athletes.

Is there ossification in the middle of the leg?

Electromyography of the lower limbs was negative. When evaluated again, deep palpation on the middle third of the left peroneal muscles elicited moderate local pain. Both ipsilateral hip and knee appeared to be normal at clinical examination. Radiographs showed a heterotopic ossification in the middle third of the leg (Figure 1 ).

Where does the ossification of the tibial diaphysis occur?

MRI of the leg showed, on T2-weighted cross-sectional fat saturation sequences, a hyperintense signal on both the lateral aspect of the periosteum and lateral part of the tibial diaphysis at the level of the ossification (Figure 3 ).

Which is the most typical form of heterotopic ossification?

Heterotopic ossification consists in bone formation outside the skeleton. The most typical form of heterotopic ossification, unrelated to surgical procedures, neurologic injuries, or tumors, is myositis ossificans circumscripta, which usually occurs after a trauma but can even be initiated by multiple minor injuries or develop spontaneously [ 1
