“…Sato et al reported excellent mid-term fixation of the S-ROM-A prosthesis. All stems showed bone ingrowth in 331 hips [16]. Compared to these previous reports, the present results for stem fixation were worse.…”

“…Le et al and Biant et al reported that no femoral components were revised with mean follow-up durations of 17 years and 10 years, respectively, using the S-ROM prosthesis [11,12]. Sato et al reported a 10-year femoral component survival rate of 84% for the S-ROM-A prosthesis, and the reason for all revisions was adverse reaction to the metal debris (ARMD) [16]. They used metal on metal, metal on polyethylene, and ceramic on polyethylene bearing surfaces, and the revision rates were 10.3%, 2.5%, and 0% respectively.…”

“…There are some reports of the short-to long-term results of the S-ROM [9][10][11][12] and S-ROM-A [13][14][15][16] prosthesis for primary THA. Although excellent fixation rates (99.5-100%) have been reported, with no evidence of aseptic loosening, we had cases of unstable fixation and revision due to aseptic loosening.…”

Purpose Although a cementless modular prosthesis has shown reliable results, cases of unstable fixation and revision due to aseptic loosening were observed in our institute. The purpose of this study was to clarify the causes of unstable fixation of the prosthesis. Methods A total of 144 patients (154 hips) who underwent total hip arthroplasty using the modular prosthesis were retrospectively investigated. For the cohort study, 97 patients (104 hips) were included. The femoral component survival rate and sleeve fixation were assessed at a minimum follow-up of 5 years. Patients were divided into 2 groups, including stable and unstable fixation groups, by sleeve fixation. Clinical and radiographic outcomes were compared. Results The Kaplan-Meier survival rate at 9 years was 93% with revision for any reason as the endpoint in study cohort. The reasons for revision were recurrent dislocation (1 hip) and aseptic loosening of the stem (5 hips). A total of 88 hips (84.6%) showed stable fixation, and 16 hips (15.4%) showed unstable fixation at final follow-up. There was no significant difference in clinical outcomes between the 2 groups at final follow-up. The canal flare index was significantly higher, and the canal filling ratio was significantly lower in the unstable fixation group. Conclusion Although the modified modular prosthesis was useful for treating anatomically difficult patients, we need to pay attention to both proximal/distal mismatch of the intramedullary canal and the canal filling ratio to achieve stable fixation and good long-term results.

“…A thin trunnion has been linked to increased risk of trunnionosis [17,18]. Sato et al [5] reported a slightly higher incidence of osteolysis in MoM THA with the S-ROM-A stem than with the original S-ROM stem. In the present study, ARMD due to trunnionosis occurred in 1 (8.3%) of the MoM cases with a 36-mm head.…”

“…This study investigated the subsequent mid-to long-term outcomes of the 220 DDH hips, focusing on the following. Firstly, an association has been suggested between the change in trunnion size in the S-ROM-A stem and increased incidence of metal-related complications at the trunnion [5]. We investigated the incidence of these complications and other late complications as well as implant failures, suspected to be related to the design modification.…”
