Abstract:
Articular cartilage defects are not often encountered in the glenohumeral joint. These lesions are typically found in patients with shoulder trauma, recurrent instability, or previous surgical treatment. Diagnosis can be difficult; these defects are often found incidentally during arthroscopic or open surgical management of other pathology. Initial management of isolated glenohumeral chondral defects is nonsurgical and includes physical therapy and/or corticosteroid injections. If nonsurgical treatment is unsuccessful, patients may undergo surgery. Because these lesions occur infrequently, few studies have documented surgical techniques and outcomes. Surgical strategies include arthroscopic débridement, microfracture surgery, osteochondral autograft or allograft transplantation, autologous chondrocyte implantation, and particulated juvenile allograft cartilage implantation.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
