In this case series we describe the diagnosis and surgical treatment of five cats
affected by clinical cauda equina syndrome as a result of degenerative lumbosacral
stenosis. Radiographic and magnetic resonance imaging findings confirmed the suspected
diagnosis of disc-associated lumbosacral disease. Cauda equina decompression was achieved
by dorsal laminectomy followed by dorsal annulectomy and nuclear extirpation. Dorsal
stabilization was achieved using miniature positive-profile pins inserted into the
vertebral body of L7 and the wings of S1 with the free ends of the pins being embedded
in a bolus of gentamicin-impregnated polymethylmethacrylate. Reassessment two years
postoperatively using a previously validated feline specific owner questionnaire indicated
satisfactory outcome with complete return to normal activity and resolution of signs
of pain in all cases.
