• Ulna osteotomies to treat bone growth issues in a young Labrador resulting from synostosis

So we removed the growth plate at the ulna's distal (bottom) end. The radius now had no bone to “argue” with. We cut through the ulna at the proximal (top) end, just below the elbow. The idea is that the triceps muscle can now pull the top fragment of the ulna back into position.
