| subtalar joint | Formed by the articulation of the talus with the calcaneus. (12 Dec 1998) |
| degenerative joint disease | <orthopaedics, rheumatology> A form of arthritis that results in the destruction of the articular cartilage that line the joints. Seen predominately in the larger weight bearing joints of the hips, knees and spine, but may also be evident in the small joints of the hands. (27 Sep 1997) |
| suture joint | <surgery> Usually a synthetic based line that is minimally reactive in biological tissue. Commonly used are nylon, Prolene and gut. Absorbable suture will dissolve over time (Vicryl and chromic). The choice in thickness (strength) of the suture is based on the location sutured. Fine suture is used for work around the eyes, face and digits. (27 Sep 1997) |
| dentoalveolar joint | <anatomy> A form of union or immovable articulation where a hard part is received into the cavity of a bone, as the teeth into the jaws. Origin: NL, fr. Gr, prop, a bolting together, fr. To fasten with bolts or nails, bolt, nail: cf. F. Gomphose. Source: Websters Dictionary (01 Mar 1998) |
| synarthrodial 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) |
| synchondrodial joint | Origin: NL, fr. Gr.; with + cartilage. <anatomy> An immovable articulation in which the union is formed by cartilage. Synchondro"sial. Source: Websters Dictionary (01 Mar 1998) |
| syndesmodial joint | Origin: NL, fr. Gr. A bond; together + a bond, fr. To bind. <anatomy> An articulation formed by means of ligaments. Source: Websters Dictionary (01 Mar 1998) |
| syndrome, joint hypermobility | See Syndrome, hypermobility. (12 Dec 1998) |
| syndrome, tempero-mandibular joint | Disorder of the temporo-mandibular joint(tmj) causing pain usually in front of the ear. Pain in the tmj can be due to trauma (such as a blow to the face), inflammatory or degenerative arthritis, or by the mandible being pushed back towards the ears whenever the patient chews or swallows. Sometimes, muscles around the tmj used for chewing can go into spasm, causing head and neck pain and difficulty opening the mouth normally. (12 Dec 1998) |
| 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) |
| diarthrodial 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) |
| distal tibiofibular joint | The fibrous union of the tibia and fibula consisting of the interosseous membrane and the anterior, interosseous and posterior tibiofibular ligaments at the distal extremities of the bones. Synonym: syndesmosis tibiofibularis, distal tibiofibular joint, inferior tibiofibular joint, tibiofibular articulation. (05 Mar 2000) |
