Management of vertebral column fractures in dogs and cats: 211 cases (1977-1985).

Hospital records and radiographs of 211 dogs and cats with vertebral column fractures or luxations evaluated at the University of Tennessee Veterinary Teaching Hospital between April 1977 and September 1985 were reviewed. After neurologic examination, status of the animal was graded on a scale of 1 to 8. Decision to treat each animal either medically or surgically was based on the extent and type of injury, neurologic signs, veterinarian's experience, and owner's wishes. After treatment, neurologic status was evaluated on the aforementioned scale and differences in the outcome of treatment were determined between surgically and medically treated groups, relative to initial neurologic status and location of the fracture. Surgically treated animals had pretreatment mean (+/- SD) neurologic status (3.71 +/- 1.35) that was slightly worse (P = 0.0079) than that of medically managed cases (5.16 +/- 1.48). Animals of the surgically treated group improved significantly (P = 0.0122) more than did those of the medically treated group but after treatment, significant differences in neurologic status were not evident between surgically (6.67 +/- 1.49) and medically (7.07 +/- 1.24) treated animals. Medically treated animals required substantially longer to reach optimal neurologic status, but the average hospital stay was nearly twice as long for the surgically treated animals (13.5 days), compared with those treated medically (7.1 days). Animals with thoracic vertebral fractures had mean neurologic status that was worse than that in animals with cervical vertebral fractures (P = 0.0109). After either medical or surgical treatment, neurologic status did not differ among animals with cervical, thoracic, or lumbar vertebral fractures.(ABSTRACT TRUNCATED AT 250 WORDS)
