[8], There are three main flexor muscles at the elbow:[10], Brachialis is the main muscle used when the elbow is flexed slowly. In contrast, freely moveable joints allow for much more extensive movements of the body and limbs. An extensive network of ligaments surrounding the joint capsule helps the elbow joint maintain its stability and resist mechanical stresses. (1 January 2015). The trochlear notch wraps about 180 degrees around the humerus, and the tight fit of the two structures enables greater stability. Its often caused by repeated stress to these muscles. Therefore, it is vital that a physician know the age of the child when examining their radiograph. Corticosteroids are another treatment option for early-stage osteoarthritis. Joints that dont move are called fixed. It is very common in the wrist, and is most common at the radioulnar joint. The ulnar collateral ligament extends from the medial epicondyle of the humerus to the coronoid process of the ulna. This is a cartilaginous joint in which the pubic regions of the right and left hip bones are strongly anchored to each other by fibrocartilage.

Sprains, strains and tears. Deep fibres of the brachialis muscle insert anteriorly into the capsule and act to pull it and the underlying membrane during flexion in order to prevent them from being pinched.

Functional classifications describe the degree of movement available between the bones, ranging from immobile, to slightly mobile, to freely moveable joints. 1 ). A uniaxial joint only allows for a motion in a single plane (around a single axis). information highlighted below and resubmit the form. In knuckle-walkers, on the other hand, the elbow has to deal with large vertical loads passing through extended forearms and the joint is therefore more expanded to provide larger articular surfaces perpendicular to those forces.
