Intervertebral disc prolapse Hansen type I ” Disc Extrusion” & Hemilaminectomy Case
(Follow up video 14 days after operation)
– A 3- years dog was presented to us in DrPaws Animal Hospital with acute onset of hind limb paralysis, urine retention & Constipation.
– The Neurological examination reveals the following:
1. Increased patellar reflex if both HL (+3)
2. Normal Flexor reflex of both HL (+2)
3. Reduced cranial tibial reflex of both HL (+1)
4. Normal sciatic reflex of both HL (+2)
5. Normal perineal reflex (+2)
6. Absent proprioception (0)
7. Normal nociception (+2)
– Type and grade of neurological deficits;
UMN deficit with Grade “4” , localized to T2-L4 spinal segments.
– Prognosis; Favorable prognosis with surgical interference.
– Decision: Computed tomography (C.T) to determine the accurate diagnosis.
– C.T reveals the following;
1. Disc extrusion (Hansen type I disc prolapse) located between T13 – L1 vertebrae.
2. Herniated disc compresses the spinal cord with 50%.
3. Herniated disc material occupies the left and right side ventrally with 70% of the herniated content at the left side.
4. No cranial or caudal migration of the herniated disc material.
Recommendations;
1. Hemilaminectomy surgical procedure to remove the herniated disc with expected recovery period upto 3 months.
2. Medical treatment (Steroid with tapering, neuro-vitamins, Gabapentin, Gastroprotectant)
Follow up videos reveals;
1. Excellent recovery at 14th day after surgery
2. With expected more improvement of the proprioception of the left leg (Video)
