Cartilaginous: C, symphysis (vertebral bodies); D, synchondrosis (first rib and sternum). Synovial: E, condyloid (wrist); F, gliding (radioulnar); G, hinge or ginglymus (elbow); H, ball and socket (hip); I, saddle (carpometacarpal of thumb); J, pivot (atlantoaxial). amphidiarthrodial joint amphidiarthrosis. arthrodial joint plane j. ball-and-socket joint spheroidal j. biaxial joint one with two chief axes of movement, at right angles to each other. bicondylar joint a condylar joint with a meniscus between the articular surfaces, such as the temporomandibular joint. bilocular joint one with two synovial compartments separated by an interarticular cartilage. cartilaginous joint a type of synarthrosis in which the bones are united by cartilage. Charcot's joint neuropathic arthropathy. Chopart's joint one between the calcaneus and the cuboid bone and the talus and navicular bone. cochlear joint a hinge joint that permits some rotation or lateral motion. composite joint , compound joint one in which several bones articulate. condylar joint , condyloid joint ellipsoidal joint; one in which an ovoid head of one bone moves in an elliptical cavity of another, permitting all movements except axial rotation. diarthrodial joint synovial j. elbow joint the articulation between the humerus, ulna, and radius. ellipsoidal joint condylar j. enarthrodial joint spheroidal j. facet joints the articulations of the vertebral column. false joint pseudarthrosis. fibrocartilaginous joint symphysis. fibrous joint a type of synarthrosis in which the bones are united by continuous intervening fibrous tissue. flail joint an unusually mobile joint. ginglymoid joint ginglymus. gliding joint plane j. hinge joint ginglymus. hip joint the spheroidal joint between the head of the femur and the acetabulum of the hip bone. immovable joint fibrous j. intercarpal joints the articulations between the carpal bones. knee joint the compound joint between the femur, patella, and tibia.

false joint Etymology: L, fallere, to deceive, jungere, to join a joint that develops at the site of a former fracture. Also called nonunion, pseudoarthrosis. false said of diseases or plants that have a superficial resemblance to another plant or disease. false acacia see robinia pseudoacacia. false blackleg cellulitis and myositis caused by Clostridium septicum and C. novyi.

Says Eiichi Fukada of the Institute of Physical and Chemical Research in Wako, Japan: "The clinical applicability of DC, AC or pulsing electric current for the treatment of nonunion [failure of the ends of a fractured bone to unite] and pseudoarthrosis [formation of a false joint by a fractured bone] has been established.
