A major veterinary surgical breakthrough occurred on October 13, 2026, in Saint-Martin-la-Plaine, where a VetAgro Sup team performed the first described bone allograft in a lion.

For nearly three years, the teams from VetAgro Sup, including Thibaut Cachon, Charles de Chaisemartin, and Morgane Gavet, had been monitoring Yembé. This lion, taken in by the association La Terre de Tonga at the Espace zoologique de Saint-Martin-la-Plaine, suffered from a complex mandibular condition.
To promote bone reconstruction and ensure the long-term healing of the wound, a particularly innovative solution was implemented: a bone allograft using tissue taken from a donor lion.
This marks the first described bone allograft in a lion, a world first that opens new avenues in veterinary surgery.
