Köpeklerde Poliaksiyel Vida-Rod Sistemiyle Stabilize Edilen Vertebral Kırıkların veya Çıkıkların Radyolojik ve Nörolojik Değerlendirmesi: On Olguluk Bir Seri

Abstract

 

 Bu çalışmanın amacı, köpeklerde torakolumbar vertebral kırıkların veya çıkıkların poliaksiyal vida rod sistemi ile stabilizasyonunu ve bunun nörolojik ve radyografik verilerini belirlemektir. Çalışmaya torakolumbar spinal instabilitesi olan on köpek dahil edilmiştir. Çalışmaya dahil edilen her köpek için tıbbi öykü, cins, cinsiyet, yaş, vücut ağırlığı, yaralanmanın etiyolojisi, eşlik eden yaralanmaların varlığı ve cerrahi müdahalenin zamanlaması ile ilgili bilgiler kaydedilmiştir. Nörolojik olmayan lezyonları dışlamak için genel ve ortopedik muayeneler yapıldı. Her köpeğin nörolojik (ameliyat öncesi, ameliyat sonrası, 1. hafta, 3. hafta) ve radyografik (ameliyat öncesi, ameliyat sonrası, 1. hafta, 3. hafta) muayene verileri kaydedildi ve değerlendirildi. En çok etkilenen bölgeler 5 vakada T3-L3 seviyesi ve 5 vakada L4-L7 seviyesiydi. Ameliyata kadar geçen ortalama süre 23.4 saat olarak kaydedildi. 4 vakada tek taraflı, 6 vakada ise çift taraflı vida yerleştirildi. Radyolojik olarak, tüm vakalarda başarılı vida yerleştirme ve önemli derecede çıkık redüksiyonu (%92.75) elde edildi. Nörolojik olarak, özellikle derin ağrı hissi olmayan vakalarda da klinik iyileşme gözlendi. Ayrıca, idrar fonksiyonlarında %80 iyileşme bildirildi. Hiçbir vakada implant gevşemesi veya hizalama kaybı gözlenmedi. Tüm vakalar 21 gün hastanede kaldı. Ameliyat sonrası 6 aylık takipte, klinik sonuç 3 vakada “mükemmel”, 5 vakada ‘fonksiyonel’ ve 2 vakada “zayıf” olarak değerlendirildi. Poliaksiyal vida-rod sistemleri, köpeklerde akut vertebral travmanın cerrahi tedavisinde güvenli ve etkili bir stabilizasyon seçeneğidir.

Radiological and Neurological Evaluation of Vertebral Fractures or Luxations Stabilized with a Polyaxial Screw-Rod System in Dogs: A Ten-Case Series

Abstract

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.
