Surgical pelvic limb amputation and tarsorrhaphy in an American Toad (Bufo americanus)

An adult male American toad (Bufo americanus) was presented to the Wildlife Medical Clinic at the University of Illinois by a member of the public after finding the toad trapped in a window well. On presentation, the toad was quiet, alert and responsive. There was an inflamed lesion at the level of the left tarsus with a section of calcaneum protruding from the wound. Initial stabilization was performed, followed by surgical amputation at the mid-tibiofibula of the left pelvic limb three days after initial presentation. The surgery was successful, and the toad recovered well from anaesthesia. Two days after the procedure, corneal edema was appreciated in the right eye consistent with acute bullous keratopathy. Initial medical management was unsuccessful, necessitating a right unilateral tarsorrhaphy. One month after initial presentation, the toad had healed from all procedures, was eating well and was manoeuvring around the enclosure appropriately. Permanent placement at a zoological facility was elected due to the extent of surgical intervention necessary for this case. This case highlights analgesic considerations, pelvic limb amputation and ophthalmological procedures that may be a plausible option for treating anurans in a wildlife setting.
