Purpose: To evaluate the clinical and radiological outcomes after revision total hip arthroplasty using the S-ROM modular system.
Materials and methods: Twenty-three consecutive patients (24 hips) who underwent femoral stem revision with the S-ROM modular system were followed for more than two years. The average follow-up period was 44 months (range, 24~72 months), and the average age at the time of the revision was 48 years (range, 30~68 years). Underlying causes for revisions included 23 cases of aseptic loosening and 1 case of septic loosening. Femoral bone defects according to the Paprosky system were classified as type II in 12 hips, type III in 8, and type IV in 4. The clinical and radiographic results were evaluated.
Results: At the time of latest follow-up, there was no femoral stem loosening, osteolysis, radiolucency, or rerevision. Although 3 cases of Paprosky classification type IV showed subsidence, stable fibrous fixation was achieved in these hips. Complications included 1 intraoperative femoral shaft crack and 1 postoperative deep infection.
Conclusion: We can achieve stable initial fixation using the S-ROM modular system with proximal press fitting sleeve and fluted stem.
