Radiological and Neurological Evaluation of Vertebral Fractures or Luxations Stabilized with a Polyaxial Screw-Rod System in Dogs: A Ten-Case Series
Öz
The purpose of this study was to determine the stabilization of thoracolumbar vertebral fractures or luxations in dogs with a polyaxial screw rod system and its neurological and radiographic data. Ten dogs with thoracolumbar spinal instability were included in the study. Information on medical history, breed, sex, age, body weight, etiology of injury, presence of concomitant injuries, and timing of surgical intervention was recorded for each dog included in the study. General and orthopedic examinations were performed to exclude non-neurological lesions. Neurological (preoperative, immediate postoperative, 1st week, 3rd week) and radiographic (preoperative, immediate postoperative, 1st week, 3rd week) examination data of each dog were recorded and evaluated. The most affected areas were the T3-L3 level in 5 cases and the L4-L7 level in 5 cases. The mean time to surgery was recorded as 23.4 hours. Screws were placed unilaterally in 4 cases and bilaterally in 6 cases. Radiologically, successful screw placement and significant dislocation reduction (92.75%) were achieved in all cases. Neurological improvement was observed, even in cases without deep pain sensation. In addition, 80% improvement was reported in urinary functions. No implant loosening or loss of alignment was observed in any case. All cases remained in the hospital for 21 days. At the 6- month follow-up after surgery, the clinical outcome was 'excellent' in 3 cases, 'functional' in 5 cases and 'poor' in 2 cases. Polyaxial screw-rod systems are a safe and effective stabilization option in the surgical treatment of acute vertebral trauma in dogs.
