Stabilisation of thoracolumbar vertebral fractures and luxations in cats with a polyaxial screw/rod system.
Objectives: The purpose of this study was to determine clinical and neurological data on the stabilisation of thoracolumbar region fractures or luxations in cats with the polyaxial screw rod system.
Materials and methods: The study included 16 cats with thoracic and/or lumbar fractures, luxations and/or instability. Data recorded for each patient included history, cause of vertebral fractures and dislocations, concurrent injury, time to surgery, neurologic examination and neurologic grading preoperatively and postoperatively (postoperatively, week 1, week 3 and month 6), surgical treatment, preoperative x-ray and postoperative computed tomography imaging findings.
Results: The region with the most localized lesions was T3-L3 in ten cases and L4-L7 in six cases. Polyaxial screws were placed unilaterally in 13 cases and bilaterally in three cases. A total of 50 polyaxial screws were placed in all cases. Of these, 44 polyaxial screws were placed optimally, four polyaxial screws were breached (screw diameter breach <2 mm) and two screws were broken. Broken screws did not require any revisions. Although 11 of the cases showed improvement in terms of neurological grading, no improvement was observed in five cases. The clinical outcome was excellent in four cases, functional in six cases and poor in six cases.
Clinical significance: The polyaxial screw rod system described here is a potential option for stabilization of thoracolumbar vertebrae in cats.
期刊介绍：
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
