Traumatic atlanto-occipital subluxation and cranial cervical block vertebraein a Golden Eagle (Aquila chrysaetos)

摘要

A Golden Eagle (Aquila chrysaetos) was evaluated for a balance/equilibrium disorder after suffering trauma due to a hard landing during fitness training. Magnetic resonance imaging and computed tomography demonstrated a chronic atlanto-occipital subluxation with craniodorsal displacement of the atlas (atlanto-occipital overlapping) causing dynamic brainstem and spinal cord compression and an old malunion fracture with fusion of CI and C2. The bird was euthanized because of clinical deterioration andpoor prognosis.
