2.  Review the history and signalment for the client  Evaluate the radiographs provided  Explore the interactive images and compare the answers given with your own interpretations. When you’ve clicked on the image, click the same spot again to make the label disappear.  Answer the questions regarding a diagnosis and recommendations  Review the radiologist’s findings

3.  Signalment: 6 year old Morgan gelding  History: presenting for colic; quiet, dull and painful; no guts can be ausculted in any quadrant; also has large painful swelling on the ventrolateral portion of the left side of the neck  Patient had colic surgery for correction of right dorsal displacement of large colon and recovered well ▪ Became severely ataxic in front and hind limbs the day after surgery  Study: lateral views of the cervical spine

4. Normal bulla Normal base of skull Normal C1-C2 Normal dens

5. Normal canal Normal articular process

6. Jugular catheter Normal articular processes Normal canal Swelling compressing trachea Small fragments from dorsal lamina C5 Comminuted fracture of caudal body C5

7.  Provide a diagnosis based on your findings. Submit Comminuted fractures of the caudal body and dorsal lamina of C5. No evidence of instability affecting the spinal canal Neurologic signs may be from contusion of cord and possible hemorrhage within the spinal canal Feedback Continue

8.  Provide your recommendation for this client. Submit Conservative management for the spinal fracture If further evaluation for spinal cord compression is clinically indicated, a cervical myelogram can be performed Feedback Continue

9.  The caudal body of C5 has a comminuted transverse fracture with ventral displacement of the caudoventral fragment  There is no step defect involving the ventral aspect of the spinal canal  At least 2 small angular bony fragments are displaced dorsally from the dorsal lamina of C5  Moderate soft tissue swelling ventral to C5 compresses on the trachea

10.  The patient was conservatively managed in hospital for 10 days  Neurologic signs improved over the 10 days  Further improvement in, and possibly complete resolution of, neurologic deficits is likely to occur with additional time and box rest. Maximal improvement is likely to be achieved within 9-12 months of injury  Patient was discharged with instructions for complete stall rest for 45 days and instructions for follow-up care for colic surgery
