Since the introduction of the low-friction total hip arthroplasty (THA) by Sir John Charnley, wear has been a primary issue in hip arthroplasty. Charnley's original choice for bearing surfaces was a stainless steel head on polytetrafluoroethylene (PTFE). This choice was complicated by a wear rate of 7-10...

Even though an enormous volume of literature concerns the anatomy and biomechanics of the hip, little of it is specifically organized from the perspective of total hip arthroplasty. Also, since an analysis of the finer elements of these factors has formed a significant part of the development of the porous...

hip joint:
- is affected in upto 50 % of patients with AS, and when it occurs it is often bilateral;

Discussion: - major problems with the Watson Jones technique are dealing w/ gluteus medius & minimus, which lie over anteior capsule and must be damaged or cut to obtain adequate exposure; - original Charnely technique...

Sufficient primary stability is a prerequisite for the clinical success of cementless implants. Therefore, it is important to have an estimation of the primary stability that can be achieved with new stem designs in a pre-clinical trial. Fast assessment of the primary stability is also useful in the preoperative planning...

The insertion of any implant or prosthesis into bone usually changes the biomechanical environment and, thus, alters the stresses and strains applied to the bone. Both bone overload and excessive stress protection can result in bone resorption. The material and geometry of any implant should be designed to avoid excessive...

Removal of well-fixed or loose, cemented (polymethylmethacrylate) total hip components presents many challenges to the orthopaedic surgeon. In cases of loose components with extensive bone-cement radiolucencies, extraction may not be too difficult because...
