LABORATORY TESTS ON TOTAL JOINT REPLACEMENT PROSTHESES

Laboratory tests on total joint replacement prostheses.

Total joint replacement is becoming a clinical commonplace. The hip is now often replaced, the knee and finger joints on a smaller but increasing scale, and widening interest is being shown in designs of implants for the total replacement of the elbow and shoulder joints. The largest experience (considering both numbers of patients and lengths of service) has been obtained with the hip, in whic...

Custom-made total joint prostheses for temporomandibular joint reconstruction.

BUMC PROCEEDINGS 2000;13:135–138 Jaw joint (temporomandibular joint or TMJ) disease is estimated to affect 30 million Americans, with approximately 1 million new patients diagnosed each year (1). Although many of these patients can be managed with nonsurgical therapies, some patients require surgical intervention. The TMJ is a unique joint in that it does not function independently but works in...

Effect of lubricants on friction in laboratory tests of a total disc replacement device.

Some designs of total disc replacement devices have articulating bearing surfaces, and these devices are tested in vitro with a lubricant of diluted calf serum. It is believed that the lubricant found in total disc replacement devices in vivo is interstitial fluid that may have properties between that in Ringer's solution and diluted calf serum. To investigate the effect of lubricants, a set of...
