Core Tip
Core tip: There are few cemented implants that have made history and are still used today. The original Müller straight stem prosthesis falls into this category. In this study, 176 primary cemented total hip replacements in 164 consecutive patients were followed-up for a mean of 10 years (3-18) years. Survival of the prosthesis, as calculated by Kaplan-Meier analysis, was 96% at 10 years and 81% at 18 years. The 18 year survivorship of the Müller straight stem, cemented total hip arthroplasty is comparable with that of other successful cemented or uncemented systems.
