Synovectomy is the surgical removal of the synovial tissue surrounding a joint.This procedure is typically recommended to provide relief from a condition in which the synovial membrane or the joint lining becomes inflamed and irritated and is not controlled by medication alone.
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).
Synovitis, a hallmark of various joint disorders, including osteoarthritis, manifests as inflammation within the synovial membrane lining the joints. RSO aims to suppress overactive macrophage and synovial cells responsible for the inflammatory response, providing relief from pain and improving joint functionality.
The synovial membrane of the elbow joint is very extensive. On the humerus, it extends up from the articular margins and covers the coronoid and radial fossae anteriorly and the olecranon fossa posteriorly. Distally, it is prolonged down to the neck of the radius and the superior radioulnar joint.
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
An injection of steroids may be done, directly into the affected joint. Injection of beta-emitting radioisotopes to locally treat synovitis has been performed in people for decades [4] and is now being applied using tin-117m in veterinary medicine to treat canine elbow synovitis. [5] Specific treatment depends on the underlying cause of the ...
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial membrane is a type of connective tissue membrane that lines the cavity of a freely movable joint. For example, synovial membranes surround the joints of the shoulder, elbow, and ...
Synovial chondromatosis is a locally aggressive bone tumor of the cartilaginous type. [1] It consists of several hyaline cartilaginous nodules and has the potential of becoming cancerous . [ 1 ]
