Synovitis is the medical term for inflammation of the synovial membrane. This membrane lines joints that possess cavities, known as synovial joints . The condition is usually painful, particularly when the joint is moved.
Animation of shoulder joint showing the supraspinatus muscle. The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the ...
Histology of a synovial membrane. H&E stain. The synovial membrane is variable but often has two layers: [4] The outer layer, or subintima, can be of almost any type of connective tissue – fibrous (dense collagenous type), adipose (fatty; e.g. in intra-articular fat pads) or areolar (loose collagenous type).

[ 3 ] These muscles are the supraspinatus , infraspinatus , teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
PVNS (Pigmented villonodular synovitis): is a joint problem that usually affects the shoulder, hip or knee. It can also affect the elbow, ankle, and hand or foot. In pigmented villonodular synovitis, the synovial joint lining becomes swollen and grows. It may harm the bone around the joint.
