Five paraplegic dogs were diagnosed with thoracolumbar intervertebral disc disease with more than 50% compression of spinal cord. Because the lesions were determined to be disc extrusion on magnetic resonance imaging, a hemilaminectomy was initially performed, however, protruded discs were confirmed during surgery. To remove the protruded disc, modified partial lateral corpectomy (mini-PLC) was additionally performed. All dogs recovered to full ambulation within a median of 44 days without temporary deterioration or vertebral instability. Mini-PLC as described here enables successful removal of the protruded disc, while preserving vertebral stability in dogs for whom the use of hemilaminectomy is inevitable.
