Summary
Cortical strut allografts are a valuable option for complex bone defects in hip revision surgery. These allografts showed excellent incorporation and no failures in a 4.3-year follow-up, aiding reconstructive orthopaedic surgery.
Area of Science:
- Orthopaedic Surgery
- Biomaterials Science
- Regenerative Medicine
Background:
- Bone grafting is crucial in reconstructive orthopaedic surgery.
- Autografts are limited by donor site morbidity and quantity.
- Allografts offer a viable alternative for significant bone loss.
Purpose of the Study:
- To evaluate radiographic outcomes of cryopreserved cortical onlay strut allografts.
- To assess allograft performance in revision hip arthroplasty and femoral reconstruction.
- To analyze allograft utility in periprosthetic fractures and nonunions.
Main Methods:
- Retrospective analysis of twelve cryopreserved cortical onlay strut allografts.
- Application in nine patients for revision hip arthroplasty, femoral fractures, and nonunion.
- Radiographic assessment over an average follow-up of 4.3 years.
Main Results:
- No fractures, nonunions, or progressive resorption observed.
- All allografts incorporated with minimal resorption within one year.
- No failures in any allograft reconstructions were reported.
Conclusions:
- Cortical onlay strut allografts are a valuable adjunct in reconstructive hip surgery.
- They effectively treat atrophic femoral nonunion and reinforce bone stock.
- Allografts demonstrate reliable incorporation and long-term stability.
