Description
Tae-Yoon Eom, Gyu-Sung Choi, and Mu-Young Kim report in 2026 a dog whose unused front leg developed a paradoxical bone overgrowth during growth. The twelve-month-old poodle could not bear weight after a failed shoulder repair left a malunion. Scans showed a complete shoulder nonunion with severe deformity, plus an ulna grown about six percent longer than its pair, misaligning the elbow joint.
Surgeons fused the shoulder using custom 3D-printed guides set at a precise angle. They also cut the ulna to restore joint fit. The dog bore weight within a month. At nine and fifteen months, function stayed normal with solid fusion.
