Hi ladies, I'm sorry to post about a pregnancy complication but I am being tested for obstetric cholestasis and am interested to hear some real experience if you don't mind/feel like sharing.
The hip joint is a spherical joint between the femoral head and the acetabulum in the pelvis (Fig. 1); it is a diarthrosis or synovial joint, since it is wrapped in a capsule that contains the synovial fluid (SF), a biological lubricant that acts also like a shock-absorber [1] .he 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.
The well-fitting surfaces of the femoral head and acetabulum, which face each other, are lined with a layer of slippery tissue called articular cartilage, which is lubricated by a thin film of synovial fluid. Friction inside a normal hip is less than one-tenth that of ice gliding on ice.ontributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline.
