Summary
Cemented total hip arthroplasty using the calcar-guided A2 stem shows promising short-term results in elderly patients. This approach demonstrated excellent functional outcomes and no infections or aseptic loosening in a recent study.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Cemented and cementless hip stems have favorable long-term outcomes.
- Cemented stems offer reduced periprosthetic fracture risk in elderly patients.
Purpose of the Study:
- To evaluate the initial outcomes of cemented total hip arthroplasty using a calcar-guided A2 stem.
- To assess clinical and radiographic results in elderly patients.
Main Methods:
- Unilateral cemented total hip arthroplasty with a calcar-guided A2 stem in 28 patients.
- Use of antibiotic-loaded bone cement.
- Clinical assessment (Harris Hip Score) and radiographic evaluation (subsidence, osteolysis, bone resorption) at 1-year follow-up.
Main Results:
- Twenty patients completed 1-year follow-up; 5 withdrew consent, 2 died from unrelated causes, and 1 prosthesis was explanted due to cement mantle issues.
- Significant improvements in clinical scores were observed.
- No radiolucent lines, osteolysis, or infections were detected.
Conclusions:
- Short-term use of the calcar-guided A2 cemented stem shows promising functional outcomes.
- The design demonstrated no aseptic loosening or infections in this cohort.
- Further studies are needed to confirm these findings with registry data.
