Summary
This study shows canine coccygeal vertebrae are reliable vascularized bone grafts for orthopedic microsurgery. The osteocutaneous flap, including skin, offers a viable option for veterinary surgical repair.
Area of Science:
- Veterinary Surgery
- Orthopedic Research
- Microsurgery
Background:
- Free vascularized bone transfer is crucial for reconstructing bone defects.
- The canine coccygeal vertebra offers a potential source for osteocutaneous flaps.
- Evaluating the viability and application of this graft is essential.
Purpose of the Study:
- To design and evaluate the canine coccygeal vertebra as a free vascularized osteocutaneous flap.
- To assess the flap's suitability for filling tibial defects in dogs.
- To compare the outcomes of vascularized versus non-vascularized bone grafts.
Main Methods:
- Cadaver studies in dogs to design the coccygeal osteocutaneous flap (8th-10th vertebrae).
- Transfer of the flap to fill tibial defects in six dogs, with vascular anastomosis.
- Radiographic and histologic examination to evaluate flap behavior and compare with controls.
Main Results:
- The canine coccygeal osteocutaneous flap demonstrated reliability in vascularized bone transfer.
- The overlying skin served as an effective monitoring system for tissue viability.
- Vascularized grafts showed successful integration compared to non-vascularized controls.
Conclusions:
- The canine coccygeal bone graft is a dependable vascularized osteocutaneous flap.
- This technique is applicable in clinical veterinary surgery.
- The flap is suitable for orthopedic microsurgical research applications.
