[Value of establishing a registry of hip prostheses in Lebanon].

A registry for hip arthroplasty is an excellent method for the surveillance of complications and of short-, mid- and long-term results of a procedure which is becoming increasingly more frequent. Surveillance may lead to improvement of results, reflected by a decrease in the rates of revisions performed after primary surgery, and of health expenses. In addition, registry data can be used for epidemiological studies. This article proposes a financial projection of savings which can be obtained as a result of hip revision rate reductions.
