Summary
Femoral impaction grafting effectively reconstructs large femoral defects, showing 90.5% survivorship over 11 years. This technique is preferred when the femoral isthmus is non-supportive, with a 5.4% average fracture rate.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Revision arthroplasty
Background:
- Femoral component revision is a common orthopedic procedure.
- Large femoral defects present significant reconstruction challenges.
- The isthmus's integrity is crucial for femoral component support.
Purpose of the Study:
- To evaluate the efficacy of femoral impaction grafting for complex femoral revisions.
- To analyze the long-term survivorship and complication rates of this technique.
Main Methods:
- Review of case series data on femoral impaction grafting.
- Analysis of survivorship endpoints (revision/re-operation).
- Assessment of femoral fracture rates as a complication.
Main Results:
- Mean survivorship of 90.5% with revision or re-operation as the endpoint.
- Average follow-up duration of 11 years.
- Average femoral fracture rate requiring re-operation/revision was 5.4% (range 2.5%-9%).
Conclusions:
- Femoral impaction grafting is a viable option for reconstructing large femoral defects, especially with isthmus compromise.
- The technique demonstrates favorable long-term survivorship.
- Femoral fracture is a recognized complication with a manageable incidence.
