Summary
The S-ROM prosthesis demonstrated good clinical and radiological outcomes for total hip arthroplasty (THA) in patients with poor femoral bone quality. This proximal modular femoral stem provided stable fixation and improved hip function in the short-to-mid term.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Medical Device Engineering
Background:
- Total hip arthroplasty (THA) is a common procedure for hip joint issues.
- Challenging femoral bone quality (Type B and C) can complicate THA outcomes.
- The S-ROM prosthesis is designed for complex femoral anatomies.
Purpose of the Study:
- To assess the clinical and radiological efficacy of the S-ROM prosthesis.
- To evaluate its use in primary total hip arthroplasty (THA) for patients with compromised femoral bone quality (Type B and C).
Main Methods:
- A cohort of sixteen hips underwent primary THA using the S-ROM prosthesis.
- Patients had a mean age of 72 years (range, 65-75).
- Follow-up averaged 38 months (range, 26-48 months).
Main Results:
- Significant improvement in average Harris hip scores from 52.2 to 88.5.
- All S-ROM femoral stems exhibited stable fixation without signs of loosening.
- No instances of osteolysis or subsidence around the femoral stem were observed at final follow-up.
Conclusions:
- The S-ROM proximal modular femoral stem is effective for THA in patients with poor bone quality.
- It yields favorable short-to-mid-term clinical and radiological results.
- The prosthesis offers a reliable solution for challenging femoral bone conditions.
