Abstract

Two cats were diagnosed with depression of caudal equina spinal nerve and lumbosacral spinal trauma that revealed rapid improving clinical signs after 1 month of dorsal laminectomy at the region of lumbar and sacral vertebrae without internal and external stabilization devices. This report showed that dorsal laminectomy was a powerful procedure for decompression caudal equina spinal injuries in stable lumbosacral vertebral trauma in cats without ancillary fixation methods. Dorsal laminectomy is valuable technique for correction of fracture/luxation of vertebrae that this procedure can reduce spinal cord edema, and axonal disruption. Stabilization of vertebrae by the orthopedic implants may be not necessary in small cat that has enough vertebral stability as the same in two these cases.

Highlights

Lumbosacral spinal injuries are the common cause that can find in vehicular accident in most cat (Scott & Mclaughlin, 2007)
Common clinical signs in cat affected by lumbosacral injuries that are pelvic limbs ataxia, pelvic limbs paralysis, urinary incontinent signs, tail paralysis, and difficulty for defecation (Janssens et al, 2009; Danielski et al, 2013)
These clinical signs occur from lumbosacral spinal cord and caudal equina nerve root injuries

Summary

Introduction

Lumbosacral spinal injuries are the common cause that can find in vehicular accident in most cat (Scott & Mclaughlin, 2007). Common clinical signs in cat affected by lumbosacral injuries that are pelvic limbs ataxia, pelvic limbs paralysis, urinary incontinent signs, tail paralysis, and difficulty for defecation (Janssens et al, 2009; Danielski et al, 2013). These clinical signs occur from lumbosacral spinal cord and caudal equina nerve root injuries. Stabilization using plate, pin, wire, and pedicle screw are necessary after laminectomy surgery but the cost of these implant is the problems for many owners so this report showed the excellent outcome for alone dorsal laminectomy surgery without implant stabilization
