The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus: [2]. One on the medial side of the joint passes from the medial edge of the glenoid cavity to the lower part of the lesser tubercle of the humerus.
The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
Anterior dislocation of the glenohumeral joint occurs when the humeral head is displaced in the anterior direction. Anterior shoulder dislocation often is a result of a blow to the shoulder while the arm is in an abducted position.
The shoulder joint, also known as the glenohumeral joint, is the major joint of the shoulder, but can more broadly include the acromioclavicular joint. In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, and the head sits in the glenoid cavity. [1]
The glenoid labrum (glenoid ligament) is a fibrocartilaginous (but not fibrocartilage, as previously thought) structure attached around the rim of the glenoid cavity on the shoulder blade.
The glenohumeral joint is the articulation between the head of the humerus and the glenoid cavity of the scapula. It is a ball and socket type of synovial joint with three rotatory and three translatory degrees of freedom. The glenohumeral joint allows for adduction, abduction, medial and lateral rotation, flexion and extension of the arm.
The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee (glenoid fossa). [5] The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words ...
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
