MEDICAL CONDITIONS OF THE SHOULDER
AT GUSTAVEL ORTHOPEDICS
The shoulder is a ball and socket joint in which the shallow nature of the socket allows for greater range of motion. The shoulder has two main joints. The humeral head and the glenoid (socket) meet to form the glenohumeral joint. The glenoid labrum, the joint capsule and the rotator cuff all help to stabilize the humeral head in the socket. The acromion and the clavicle meet to form the acromioclavicular (AC) joint. The AC joint is stabilized by ligaments and serves as a pivot point, further increasing our range of motion. There is a lubricating sac known as the bursa that lies just underneath the acromion and above the rotator cuff that allows the rotator cuff to glide more easily when you move your arm.
The shoulder is the most mobile joint in the body. That mobility allows us to use our shoulder in a variety of ways. Some people lack the strength to go along with that mobility which can lead to problems in the shoulder joint.
