Loss of sensory perception signifies severe spinal cord injury and is associated with a decreased chance of recovery following treatment. Intervention should be carried out as early as possible following onset of neurological deficits. Routine radiographs and a myelogram are produced to pinpoint the location of the extruded disc. During a myelogram, a spinal tap is performed, contrast material is injected, and radiographs are taken. If an extruded disc is present, the contrast material is displaced.
Cerebrospinal fluid is saved for analysis if necessary.
If the diagnosis of an extruded disc is made, animals usually go immediately from radiology to surgery while under anesthesia. Surgery requires special instrumentation and meticulous technique. Surgery is performed to remove extruded disc material and relieve excessive pressure on the spinal cord.
