The glenohumeral joint is one of the joints related with the shoulder support that permit a full scope of development of the upper appendage. For fulfillment, alternate joints are the sternoclavicular, acromioclavicular, and scapulothoracic joints.
Contrasted with the hip joint, the glenohumeral joint is worked for versatility and is in this manner naturally less steady than the hip joint. This trade-off among portability and security means that the shoulder joint is inclined to damage since quite a bit of what dependability the shoulder joint has depended on the tendons and muscles that encompass the joint.
To comprehend this propensity for damage, we will initially take a gander at the hard life systems that make the portability at the shoulder, and afterward, we will examine how the glenohumeral joint is fortified by both the tendons and muscles that cross the joint, with the specific spotlight on the rotator sleeve muscles. Ultimately, we will apply what we find out about the joint to normal wounds including the glenohumeral joint.

Anatomy glenohumeral joint
The glenohumeral joint is basically the verbalization between the along the side anticipating glenoid fossa (sorrow), or glenoid pit, of the scapula and the leader of the humerus. At the point when contrasted with its partner in the hip, the hip bone socket, the glenoid fossa is very shallow and acknowledges just around 1/3 of the leader of the humerus.
Shoulder joint (Articulatioglenohumeralis)
Despite the fact that the glenoid fossa is extended and amplified somewhat by the glenoid labrum, a ring of fibrocartilage appending to the outside edge of the fossa, the shallowness of the glenoid fossa makes a joint that is versatile, yet less steady than the hip joint.
As a synovial joint, the enunciation between the glenoid fossa and the humeral head has various highlights normal for these sorts of joints. One is a container that encompasses the joint depression and encases synovial liquid that greases up within the joint and the articular surfaces. Medially, it connects to the external edge of the glenoid fossa (outside of the labrum) and horizontally to the anatomical neck of the humerus which lies only distal to the leader of the humerus. Poorly, the case is looser, and will in general lie in folds when the arm is completely addicted. These folds consider snatching of the arm, amid which they progress toward becoming educated.
