Fixation of Synovial Joints
The subject is truly vast, far greater than will be encompassed in this paper which can be best deal with various examples. It should be realised that virtually any fairly solid substance may be called upon as a bearing material. It is easy to quote common examples which use rubies, wood, rubber, leather etc. as bearing materials and this diversity is only a microcosmic part of the range availa...
متن کاملSynovial Joints and Lubrication mechanisms
Synovial joints form the most important feature of the human body as they represent the centers of the most essential and basic activity in the human beings, which is motion. A synovial joint can be described as a load carrying system consisting of two mating bones with tangential and /or normal motions. The bone ends, which are usually spherical in appearance, are covered with a soft sponge li...
متن کاملFormation of synovial joints and articular cartilage.
Chondrocytes differentiate from mesenchymal progenitors and produce templates(anlagen) for the developing bones. Chondrocyte differentiation is controlled by Sox transcription factors. Templates for the neighbour bones are subsequently separated by conversion of differentiated chondrocytes into non-chondrogenic cells and emergence of interzone in which joints cavitation occurs. A central role i...
متن کاملElimination of fibrinogen from synovial joints.
When blood clots in a test-tube, fibrin strands form which enmesh the red blood cells and a clear serum is exuded as the clot retracts. When blood is shed into the cavity of a synovial joint it may coagulate in part, forming a relatively soft clot, but much of it remains apparently unaltered as a blood-like fluid. The red blood cells are not caught up in a fibrin network and there is no separat...
متن کاملComponents of the fibrinolytic system in synovial joints. Normal bovine compared with normal and abnormal human synovial joints.
Fibrinogen is not normally found in human synovial fluid (Ropes and Bauer, 1953) or in bovine synovial fluid (Cho and Neuhaus, 1960). Normal synovial joints are quite rapidly cleared of fibrin after injury (Harrold, 1961). In rheumatoid arthritis and tuberculous arthritis, fibrinogen entering the joint is precipitated as fibrin and in many cases this is not removed but remains to form fibrin bo...
