Common Shoulder Conditions
© 2016 Peter Hallam
There are two joints in the area of the shoulder. One is located where the collarbone (clavicle) meets the tip of the shoulder bone (acromion). This is called the acromioclavicular joint or ACJ. The junction of the upper arm bone (humerus) with the shoulder blade (scapula) is called the glenohumeral joint. This joint may be affected by arthritis. Arthritis of the shoulder is not uncommon.
Pain and stiffness. Pain at night can be a particularly troubling feature.
X rays and sometimes either an MRI scan or CT scan.
Non-Operative: Some arthritic shoulders joint respond to a course of physiotherapy.
Operative: If there has been no improvement with physiotherapy then a shoulder replacement can be carried out. The exact type of replacement surgery depends on x-ray findings and the state of the rotator cuff tendon. The commonest shoulder replacement is a resurfacing of the ball but in some circumstances the socket is also replaced.
