Summary
This study on cemented custom femoral stems in total hip replacement (THR) found a 10-year survival rate of 96.05%. Results are encouraging, with low revision rates for aseptic loosening.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
- Clinical Outcomes Research
Background:
- Total hip replacement (THR) is a common procedure for hip osteoarthritis.
- Custom femoral stems offer potential for improved fit and function.
- Long-term outcomes of cemented custom femoral stems require evaluation.
Purpose of the Study:
- To evaluate the 10-year survival and revision rates of cemented custom-made femoral stems and cemented HDP acetabular components in total hip replacement.
- To assess the causes of revision surgery in this patient cohort.
Main Methods:
- A retrospective review of 706 patients (759 hip implants) undergoing total hip replacement with cemented custom femoral stems and cemented HDP acetabular components.
- Kaplan-Meier survival analysis was used to determine implant survival.
- Patient follow-up included in-person reviews, telephone assessments, and review of medical records.
Main Results:
- The 10-year median survival for all components was 96.05% (95% CI: 94.41% to 97.22%).
- Revision surgery was required in 3.9% of cases (30/759 implants).
- Infection or dislocation accounted for 21 of the 30 revisions; aseptic loosening of the stem occurred in only 2 cases (0.3%).
Conclusions:
- Cemented custom-made femoral stems demonstrate encouraging 10-year results in total hip replacement.
- The survival rates and low incidence of aseptic loosening compare favorably with other cemented THR systems.
- Further research into long-term performance and specific indications for custom stems is warranted.
