How many compartments does the forearm have?
How many compartments does the forearm have?
Two bones, the radius laterally and the ulna medially, form the forearm. It has two compartments, the anterior (flexor) and posterior (extensor). The two compartments together have twenty muscles.
What are the compartments of the arm?
The compartments of the arm are the anterior compartment of the arm and the posterior compartment of the arm, divided by the lateral and the medial intermuscular septa. The compartments of the forearm are the anterior compartment of the forearm and posterior compartment of the forearm.
What are Osteofascial compartments?
Anatomically, the osteofascial compartment is surrounded by tibia, fibula, intermuscular septa, and deep fascia, so it is relatively encapsulated. When the leg had a trauma, the pressure, produced by tissue swelling, edema, exudation, and bleeding, increases dramatically and can result in ischemic and necrosis.
What is the dorsal forearm?
The dorsal compartment of the forearm contains nine muscles: four belong to the superficial group (extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris and anconeus) and five to the deep group (supinator, abductor longus, extensor pollicis brevis, extensor pollicis longus, and extensor indices).
How many compartments does the ARM have?
Anatomically, the upper arm contains three compartments including the anterior (flexor), posterior (extensor), and the deltoid compartment.
How many compartments are in the arm?
What are compartments anatomy?
Compartments are groupings of muscles, nerves, and blood vessels in your arms and legs. Covering these tissues is a tough membrane called a fascia. The role of the fascia is to keep the tissues in place, and, therefore, the fascia does not stretch or expand easily.
What is radial side of forearm?
The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna….Radius (bone)

What are the two compartments of the forearm?
The muscles of the forearm that act upon the elbow, wrist complex, and the digital joints are organized into two fascial compartments, similar to those of the arm muscles. The anterior compartment contains flexor muscles and the posterior compartment contains extensor muscles.
What are the superficial muscles of the anterior forearm?
Fig 1 – The superficial muscles of the anterior forearm. The flexor digitorum superficialis is the only muscle of the intermediate compartment. It can sometimes be classed as a superficial muscle, but in most cadavers it lies between the deep and superficial muscle layers.
What is compcompartment syndrome of the forearm?
Compartment Syndrome of the forearm is a condition in which pressure inside the closed osteofascial compartment increases to such an extent that there is a compromise of microcirculation, leading to tissue damage.
How many muscles are there in the forearm?
This field is for validation purposes and should be left unchanged. The forearm is the portion of the arm distal to the elbow and proximal to the wrist. There are 20 muscles separated into two compartments .
