Analysis of surgical correction of atlantoaxial instability in dogs

Effectiveness of ventral surgical approach in correction atlanto-axial instability dogs toy breeds was analyzed the research. 135 clinical cases correction, general concept access and implant placement, which minimize risks iatrogenic complications, were studied. Ventral stabilization carried out by forming an arthrodesis between atlas epistropheus inserting screws or spokes through articular structures vertebral bodies from surface then fixing them with bone cement. In studied method, there are also complications form failure metal damage to recurrent laryngeal nerve, but, according statistics, incidence these world practice does not exceed 20 %. Among possible during operation death animal because sudden respiratory arrest associated spinal cord injury, migration breakage implants, inadequate alignment spine. addition, implants may be placed correctly causing chronic pain cord. As a result operation, 104 fully recovered, partial preservation neurological deficit observed 13 animals, 18 animals died early postoperative period. Complications that did lead deterioration status quality life occurred 17 animals. Analyzing work done, method treatment can recommended as most reliable optimal since it is technically simple has good long-term results. Statistical data showed results, effective allows return more than 86 % cases.
