Summary
Total femoral prostheses provide an alternative to limb amputation for complex femur issues. Recent designs offer improved bone preservation and stability, even with extensive acetabular destruction.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Oncology
Background:
- Total femoral prostheses are an alternative to amputation for limb salvage.
- Indications for use in primary bone tumors and pathological fractures are limited.
- Specialized centers see increased need due to failed prior procedures, bone loss, infection, or non-union.
Purpose of the Study:
- To describe the development and application of total femoral prostheses.
- To highlight advancements in prosthesis design for complex cases.
Main Methods:
- Development of four basic total femoral prosthesis models over eight years.
- Focus on designs accommodating bone preservation or acetabular reconstruction.
Main Results:
- The most recent designs enable preservation of non-involved bone.
- Designs provide stable support in cases of complete acetabular destruction.
Conclusions:
- Total femoral prostheses are a viable option for limb salvage in challenging cases.
- Evolving designs enhance functional outcomes and bone stock preservation.
