The S-ROM cementless femoral stem: history and literature review

The S-ROM femoral prosthesis, building on the foundation of the Sivash Stem, pioneered proximal modularity in total hip arthroplasty. Now with a clinical history dating back >20 years, the S-ROM has performed well in the primary and revision setting. Early concerns regarding fretting and failure at the modular junction have been overcome by basic science data and uncomplicated mid- to long-term clinical follow-up. Coupled with its clinical performance, the versatility of the stem has enabled the S-ROM to achieve a well-deserved prominence for use in complex and straightforward primary and revision total hip arthroplasty.
