Diagnosis of skeletal injuries in Chelonians using computed tomography

Computed tomography (CT) was used to diagnose the cause of lameness in a radiated tortoise (Geochelone radiata) and to determine the extent of shell and skeletal trauma in two snapping turtles (Chelydra serpentina). The radiated tortoise's lameness was ultimately attributed to luxation of the right-shoulder joint that was not detected during plain film radiography. Axial and appendicular fractures were identified in one of the snapping turtles that were not detected during plain film radiography. In each patient, the information obtained during CT provided important diagnostic, therapeutic, or prognostic information.
