Harvesting spongy bone from the proximal humerus of the dog

To perform spongy bone harvesting at the level of the greater tubercle of the humerus, the humerus is rotated outwards to expose the area. A semi-circular incision is made, and the brachiocephalic and supraspinatus muscles are visible. An intermuscular area is located caudal to the brachiocephalic muscle to access the bony area of the greater tubercle. A small window is created over the greater tubercle, and a hole is drilled. The diameter of the hole is enlarged, and a curette is used to search for the spongy region of the bone. The quantity of spongy bone to extract depends on the purpose of the harvesting. Once all necessary spongy bone is extracted, the incision is closed by bringing each layer together.
