Modes of lubrication in human hip joints.
Cadaveric hip joints were tested in a hip function simulator which subjected the femoral head to a cycle of loading and oscillation similar to that experienced during walking and measured the frictional torque transmitted to the acetabulum. Silicone fluids with viscosities from 10-2 Pa s (pascal second) to 30 Pa s were used as lubricants and the transition from mixed to full fluid film lubricat...
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 کاملLubrication and wear modelling of artificial hip joints: A review
The tribological performance of artificial hip joints is a critical issue for their success, because adverse tissue reaction to wear debris causes loosening and failure. Many studies on wear and lubrication of hip prostheses have been published in the last 10 years, mostly on experimental tests. Theoretical/ numerical models have been proposed for investigating geometrical and material paramete...
متن کاملSupramolecular synergy in the boundary lubrication of synovial joints
Hyaluronan, lubricin and phospholipids, molecules ubiquitous in synovial joints, such as hips and knees, have separately been invoked as the lubricants responsible for the remarkable lubrication of articular cartilage; but alone, these molecules cannot explain the extremely low friction at the high pressures of such joints. We find that surface-anchored hyaluronan molecules complex synergistica...
متن کاملHydrostatic and boundary lubrication of joints--nature of boundary lubricant.
A very low coefficient of friction in joints makes it difficult to define clearly the mechanism of cartilage lubrication. The present paper describes the two currently predominant and mutually complementary views aiming to elucidate this mechanism. The first mechanism, referred to as hydrostatic lubrication, involves interstitial fluid pressurization from the cartilage and its importance for th...
