| synovial joint | A joint in which the opposing bony surfaces are covered with a layer of hyaline cartilage or fibrocartilage, there is a joint cavity containing synovial fluid, lined with synovial membrane and reinforced by a fibrous capsule and ligaments, and there is some degree of free movement possible. Synonym: articulatio synovialis, diarthrodial joint, diarthrosis, junctura synovialis, movable joint, perarticulation. (05 Mar 2000) |

| disease, degenerative joint | Also known as osteoarthritis, this type of arthritis is caused by inflammation, breakdown and eventual loss of the cartilage of the joints. Among the over 100 different types of arthritis conditions, osteoarthritis is the most common, affecting usually the hands, feet, spine, and large weight-bearing joints, such as the hips and knees. Also called degenerative arthritis. (12 Dec 1998) |
| distal radioulnar joint | The pivot synovial joint between the head of the ulna and the ulnar notch on the radius; an articular disk passes across the distal part of the joint. Synonym: articulatio radioulnaris distalis, distal radioulnar articulation, inferior radioulnar joint. (05 Mar 2000) |
| immovable joint | A union of two bones by fibrous tissue such that there is no joint cavity and almost no motion possible; the types of fibrous joints are sutures, syndesmoses, and gomphoses. Synonym: articulatio fibrosa, immovable joint, junctura fibrosa, synarthrodia, synarthrodial joint. (05 Mar 2000) |
| incudomalleolar joint | The saddle synovial joint between the incus and the malleus. Synonym: articulatio incudomallearis, incudomalleolar articulation. (05 Mar 2000) |
| incudostapedial joint | The synovial joint between the lenticular process on the long crus of the incus and the head of the stapes. Synonym: articulatio incudostapedia, incudostapedial articulation. (05 Mar 2000) |
| inferior radioulnar joint | The pivot synovial joint between the head of the ulna and the ulnar notch on the radius; an articular disk passes across the distal part of the joint. Synonym: articulatio radioulnaris distalis, distal radioulnar articulation, inferior radioulnar joint. (05 Mar 2000) |
| internal semilunar fibrocartilage of knee joint | <anatomy> A flat disc-shaped ligament which stabilises and supports the inner aspect of the knee joint. Commonly injured in knee sprains. (27 Sep 1997) |
| intracapsular temporomandibular joint arthroplasty | <orthopaedics, procedure> Operative recontouring of the articular surface of the mandibular condyle without the removal of the articular disk. (05 Mar 2000) |
| oblique ligament of elbow joint | A slender band extending from the lateral part of the coronoid process of the ulna distad and laterad to the radius immediately distal to the bicipital tuberosity. Synonym: chorda obliqua, oblique cord, round ligament of elbow joint, Weitbrecht's cord, Weitbrecht's ligament. (05 Mar 2000) |
| talocalcaneal joint | Formed by the articulation of the talus with the calcaneus. (12 Dec 1998) |
| talocalcaneonavicular joint | A ball-and-socket synovial joint, part of which participates in the transverse tarsal joint, formed by the head of the talus articulating with the navicular bone and the anterior part of the calcaneus. Synonym: articulatio talocalcaneonavicularis. (05 Mar 2000) |
| talocrural joint | The joint that is formed by the inferior articular and malleolar articular surfaces of the tibia, the malleolar articular surface of the fibula, and the medial malleolar, lateral malleolar, and superior surfaces of the talus. (12 Dec 1998) |
| talonavicular joint | The part of the talocalcaneonavicular joint which forms the medial element of the compound transverse tarsal joint. (05 Mar 2000) |
