Bawale R, Matar HE, Illanes FL, et al. - This research sought to present the long-term survivorship and radiographic outcomes of complex primary total hip arthroplasty (THA) using a modular cementless stem (S-ROM). Researchers conducted a retrospective consecutive study including a total of 167 patients (167 hips); 97 males and 70 females with an average age at the time of surgery of 55 years (range 22-76). All individuals had undergone complex THA by the senior author 1987-1999. Individuals were distinguished using a prospective database. The outcomes of this study revealed that the S-ROM stem has stood the test of time with long-term 30 years survivorship of 97.6% and continues to play an important role in modern hip surgery providing longevity and versatility in a single designer surgeon series. There is a need for further comparative long-term studies from independent centres for a definitive conclusion.
