What does the interosseous membrane do?
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.
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.
What kind of joint is 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 goes through interosseous membrane?
The interosseous membrane of the leg is also referred to as the middle tibiofibular ligament. This ligament extends through the fibula and tibia’s interosseous crests and separates the muscles in the back of the leg from the muscles located in the front of the leg.
What is a syndesmosis?
A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments.
How do you heal the interosseous membrane?
The treatments described for this injury consist of open reduction and internal fixation with osteosynthesis, or replacement of the radius dome plus fixation of distal radioulnar joint. An anatomical reconstruction of the interosseous membrane has been proposed to restore the biomechanical axis of the forearm.
How do you treat syndesmosis injury?
How are these injuries treated? Rest, ice, compression, and elevation (RICE) are the first steps following an ankle injury. After that, treatment depends on the specifics of the injury. Recovery time following syndesmosis sprain can take twice as long as recovery from other ankle sprains.
Is the interosseous membrane a syndesmosis?
An 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 muscles attach to interosseous membrane?
It is in relation, in front, with the Tibialis anterior, Extensor digitorum longus, Extensor hallucis proprius, Peronæus tertius, and the anterior tibial vessels and deep peroneal nerve; behind, with the Tibialis posterior and Flexor hallucis longus.
Is interosseous membrane syndesmosis?
What passes through interosseous membrane leg?
In its lower part is an opening for the passage of the anterior peroneal vessels. It is continuous below with the interosseous ligament of the tibiofibular syndesmosis, and presents numerous perforations for the passage of small vessels….

Why is the syndesmosis important?
The function of syndesmosis ligament complex: Provide strong stabilization and dynamic support to the ankle mortise. Maintain the integrity between the distal tibia and fibula. Resist forces (axial, rotational, and translational) that attempt to separate the two bones.
Where is the syndesmosis located?
ankle joint
The syndesmosis is a fibrous joint held together by ligaments. It’s located near the ankle joint, between the tibia, or shinbone, and the distal fibula, or outside leg bone. That’s why it’s also called the distal tibiofibular syndesmosis.
How long does it take for syndesmosis ligaments to heal?
How long does syndesmosis take to heal? Syndesmosis injuries generally involve a period of immobilisation for 4-6 weeks depending on severity. (Yes that means a moon boot!) Following this we allow a further 6-12 weeks for a full recovery.
How is syndesmosis injury diagnosed?
Clinical diagnosis The diagnosis of syndesmosis injury is based on injury pattern, thorough physical examination, and radiographic findings. When no fracture is present, clinical findings will include ankle pain, tenderness directly over the anterior syndesmosis, and positive squeeze and external rotation tests.
What are the 2 syndesmotic ligaments in the ankle?
The primary ones are: anterior inferior tibiofibular ligament. posterior inferior tibiofibular ligament. interosseous ligament.
