Summary
A novel "double barrel" free vascularized fibular graft technique enhances bone reconstruction. This modification provides dual vascular supply for improved healing in complex bone defects.
Area of Science:
- Orthopedic Surgery
- Vascularized Bone Grafting
- Microsurgery
Background:
- Free vascularized fibular grafts are crucial for reconstructing large bone defects.
- Existing techniques face challenges in optimizing vascularity for complex defects.
- Segmental bone loss requires innovative reconstructive strategies.
Purpose of the Study:
- To describe a modified free vascularized fibular graft technique.
- To evaluate the feasibility and application of the "double barrel" graft.
- To address challenges in reconstructing distal femur and radius/ulna defects.
Main Methods:
- A transverse osteotomy creates two parallel vascularized fibular bone struts.
- The struts remain connected by periosteum and a muscle cuff around the peroneal vessels.
- The proximal strut receives periosteal and endosteal blood supply; the distal strut receives periosteal supply.
Main Results:
- The technique was successfully applied in four patients.
- Three patients had segmental bone defects of the distal femur.
- One patient had adjacent bony defects of the radius and ulna.
Conclusions:
- The "double barrel" free vascularized fibular graft is a viable modification for complex bone defects.
- This technique potentially enhances graft survival and integration.
- Further studies are warranted to assess long-term outcomes.
