Summary
Revision total hip arthroplasty using cementless distal interlocking femoral stems demonstrated satisfactory outcomes. This approach offers excellent stability and bone ingrowth, reducing the need for repeat procedures.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Background:
- Revision total hip arthroplasty presents challenges in achieving stable fixation.
- Cementless femoral stems require robust integration for long-term success.
Purpose of the Study:
- To evaluate the efficacy of cementless distal interlocking femoral stems in revision total hip arthroplasty.
- To assess radiographic and clinical outcomes of the BiCONTACT stem.
Main Methods:
- Retrospective analysis of 68 consecutive revision total hip arthroplasties.
- Utilized cementless distal interlocking femoral stems (BiCONTACT).
- Follow-up included clinical assessment (Harris hip score) and radiographic evaluation.
Main Results:
- Significant improvement in average Harris hip score from 60 to 88.
- All cases showed radiographic evidence of bone ingrowth with no subsidence, osteolysis, or loosening.
- No repeat revisions were required during the average 40-month follow-up.
Conclusions:
- Cementless distal interlocking femoral stems provide satisfactory results in revision total hip arthroplasty.
- Diaphyseal fixation with distal interlocking screws ensures primary axial and rotational stability.
- This technique is a viable option for revision hip surgery.
