Arthrography of shoulder joint (with or without computed tomography) is performed by injecting contrast below and lateral to the coracoid process to outline the shoulder joint. Axillary pouch of the shoulder can be seen on external rotation, while subscapular (subcoracoid) bursa can be seen on internal rotation of arm. The contrast should not ...
Each exercise is demonstrated by Rothberg in the video above so you can learn proper form. You will need a set of light dumbbells, a medium to heavy weight dumbbell, and a yoga mat is optional. 1.
The most important ligament involved in shoulder joint stability is the Inferior Glenohumeral Ligament. During abduction of the arm, the middle and inferior ligaments become taut while the superior ligament relaxes. The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments ...
The lifter stands erect, hands about shoulder width apart, and slowly raises the shoulders as high as possible, and then slowly lowers them, while not bending the elbows, or moving the body at all. [2] The lifter may not have as large a range of motion as in a normal shrug done for active flexibility. It is usually considered good form if the ...
Dumbbell shoulder fly. The shoulder fly (also known as a lateral raise) works the deltoid muscle of the shoulder. The movement starts with the arms straight, and the hands holding weights at the sides or in front of the body. Body is in a slight forward-leaning position with hips and knees bent a little.
These exercises are used to increase stability, strength and range of motion of the subscapularis, supraspinatus, infraspinatus, and teres minor muscles within the rotator cuff. [26] Passive exercises include internal and external rotation of the shoulder joint, as well as flexion and extension of the shoulder. [26]
Cross-section of shoulder joint. The shoulder joint (also known as the glenohumeral joint) is the main joint of the shoulder. [1] It is a ball and socket joint that allows the arm to rotate in a circular fashion or to hinge out and up away from the body. It is formed by the articulation between the head of the humerus and the lateral scapula ...
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.
