Intra-articular
Intra-articular
In medicine, a joint injection (intra-articular injection) is a procedure used in the treatment of inflammatory joint conditions, such as rheumatoid arthritis, psoriatic arthritis, gout, tendinitis, bursitis, Carpal Tunnel Syndrome, and occasionally osteoarthritis.
In joint: Intra-articular fibrocartilages. Intra-articular fibrocartilages are complete or incomplete plates of fibrocartilage that are attached to the joint capsule (the investing ligament) and that stretch across the joint cavity between a pair of conarticular surfaces.

joint capsule
In anatomy, a joint capsule or articular capsule is an envelope surrounding a synovial joint. Each joint capsule has two parts: an outer fibrous layer or membrane, and an inner synovial layer or membrane.
(the investing ligament) and that stretch across the joint cavity between a pair of conarticular surfaces. When complete they are called disks; when incomplete they are called menisci.
Where is the articular disc located?
The articular disk is a thin, oval plate, placed between the condyle of the mandible and the mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle. Its under surface, in contact with the condyle, is concave.
What is intra-articular disc made of?
The temporomandibular joint's articular disc is a biconcave structure made up of fibrocartilage tissue; it can be divided into three different functional portions: posterior band, intermediate zone and anterior band [1,2,3].
How do you treat TMJ disc displacement?
Less frequently, the disk remains displaced and jaw opening is restricted. Diagnosis is based on history and physical examination. Treatment is with analgesics, jaw rest, muscle relaxation, physical therapy, and oral appliance therapy. If these methods fail, surgery may be necessary.
What does the articular disk of TMJ do?
The articular disc in the TMJ has an important functional role. It fills the space between the condyle and the temporal bone, and acts as a stress absorber and distributors during the jaw activity.
