[Choice of hip prosthesis in patients younger than 50 years].
There is no agreement about the most ideal type of hip prosthesis to be used in patients younger than 50 years. The most commonly used hip prostheses in patients younger than 50 years are uncemented or resurfacing prostheses and to a lesser extent cemented prostheses. A good result of a hip prosthesis can be defined as follows: 10 years after surgery more than 90% of the prostheses should be still in situ during endpoint revision for any reason. No trials are available comparing cemented, uncemented or resurfacing hip prostheses. Studies are available of cemented hip prostheses in patients younger than 50 years that prove that more than 90% of the hips are still in situ after 50 years. There are no studies available of uncemented or resurfacing hip prostheses in younger patients that prove that after to years of follow-up 90% or more of the prostheses are still in situ. The Scandinavian hip registers show that the highest rate of prostheses still in situ after 10 years is achieved by cemented hip prostheses.
