Biomechanical Considerations for Total Hip Replacement

Basic Science Considerations in Primary Total Hip Replacement Arthroplasty

Total Hip Replacement is one of the most common operations performed in the developed world today. An increasingly ageing population means that the numbers of people undergoing this operation is set to rise. There are a numerous number of prosthesis on the market and it is often difficult to choose between them. It is therefore necessary to have a good understanding of the basic scientific prin...

A comparison of leg length and femoral offset discrepancies in hip resurfacing, large head metal-on- metal and conventional total hip replacement: a case series

BACKGROUND A discrepancy in leg length and femoral offset restoration is the leading cause of patient dissatisfaction in hip replacement surgery and has profound implications on patient quality of life. The aim of this study is to compare biomechanical hip reconstruction in hip resurfacing, large-diameter femoral head hip arthroplasty and conventional total hip replacement. METHOD Sixty patie...

The influence of femoral head size following total hip replacement and hip resurfacing on hip biomechanics during walking, stair use and sit-to-stand

Due to geometrical features, it is claimed that larger femoral heads in total hip replacement (THR) are superior in achieving normal biomechanics than smaller ones; and that hip resurfacing (RSF) is superior to THR. This has not been conclusively proven. Most studies have investigated level walking, which may not be demanding enough to highlight what could be small biomechanical differences bet...

University of Groningen The biomechanical outcome after total hip replacement

Hip Resurfacing

When Policy Topic is covered Metal-on-metal total hip resurfacing with a device system approved by the U.S. Food and Drug Administration (FDA) may be considered medically necessary as an alternative to total hip replacement when the patient:  Is a candidate for total hip replacement; AND  Is likely to outlive a traditional prosthesis; AND  Does not have a contraindication for total hip resur...
