Surgical decompression of a caudal vertebral disc extrusion by dorsal laminectomy

Abstract

SummaryA 3.5-year-old female spayed Beagle cross was presented to our emergency and referral facility for the complaint of acute onset paralysis of the tail. A full physical and neurological examination was performed which confirmed the absence of motor function in the tail. Signs of superficial and deep pain sensation to the tail remained intact. Orthogonal view survey radiographs identified mineralization superimposed over the intervertebral foramen of the first and second caudal vertebrae. A dorsal laminectomy was performed for surgical decompression of the caudal nerve roots. On the fourth postoperative day, the patient exhibited good motor function of the tail. Neurological improvement continued and 11 days postoperatively the patient demonstrated normal neurological function, free range-of-motion of the tail, and it did not exhibit any signs of pain. Follow-up examination was performed 76 days after surgery, at which time the patient exhibited normal neurological function and signs of a pain-free range-of-motion on manipulation of its tail.
