Excision arthroplasty of the hip joint in dogs: the role of age, weight, degenerative joint disease on the outcome

Bu klinik çalışma, köpeklerde kalça eklemi eksizyonu artroplastisi geçiren hastalarda yaş, ağırlık ve dejeneratif eklem hastalığı (DEH) arasındaki ilişkinin sonuç üzerine etkisini değerlendirmektedir. Arka ayaklarında topallık şikayeti ile kliniğe sevk edilen 105 adet köpek kullanılmıştır. Köpeklerin yaş dağılımı, 1 yaşından genç (50 köpek), 1 ile 5 yaşlı (24) ve 5 yıldan yaşlı (31) şeklindeydi. Bunlardan geri kalanlar, 10 kg’dan az ve diğer geri kalanı ise 10 kg’dan daha ağır hayvanlardı. Yürüyüş sırasında topallığa sıfır ile 5 arasında skor verildi. Radyografik bulgular ile dejeneratif eklem değişikliği, kalça displazisi ve çıkık belirledi. Kalça ekleminin eksizyon artroplastisi yapıldı ve yürüme durumlarının takibi gerçekleştirildi. Grup içi veriler, 1 yaşından genç köpeklerde ağırlığın etkili bir faktör olmadığını ve DEH ile sonuç arasındaki ilişkinin her iki ağırlıkta istatistiksel olarak anlamlı olduğunu gösterdi. DEH’in 10 kg’dan daha az köpeklerde 10 kg’dan daha fazla olanlara göre etkili bir role sahip olduğu görüldü. DEH ile sonuç arasındaki ilişkinin her iki ağırlıktaki 1- 5 yaş arası köpeklerde istatistiksel olarak anlamlı olmadığı gözlemlendi. Daha yaşlı köpeklerde, ağırlığın başlıca faktör olmadığı ve DEH ile sonuç arasındaki ilişkinin ilişkinin her iki ağırlıkta da istatistiksel olarak anlamlı olduğu belirlendi. Sonraki grupta, DEH’in 10 kg’dan daha az köpeklerde 10 kg’dan daha fazla olanlarla karşılaştırıldığında sonuç üzerine etkili bir role sahip olduğu gözlemlendi. Sonuç olarak, kalça ekleminin eksizyon artroplastisi sonrası yapılan çalışma gruplarında ağırlığın yaş kadar etkili bir faktör olmadığı düşünülmektedir.

Köpeklerde kalça eklemi eksizyonu artroplastisi: yaş, ağırlık ve dejeneratif eklem hastalığının sonuç üzerine etkisi

The present clinical study was to evaluate the relationship between weight, degenerative joint disease (DJD) and age on the outcome in dogs underwent excision arthroplasty operation. 105 dogs have been referred to clinic with lameness on hindlimb. Dogs were younger than 1 year (50 dogs), 1 to 5 years (24) and older than 5 years (31). The rest of them were less than 10kg and the rest were heavier than 10kg. Lameness during walking was scored between zero to 5. Radiographic findings were showed that degenerative joint change, hip dysplasia and luxation. Excision arthroplasty of the hip joint was performed. Walking status was examined postoperatively. Intra-group data showed in dogs younger than 1 year, weight was not an effective factor, and association between DJD and the outcome was statistically significant in both weights. DJD had effective role in dogs more than 10kg in comparison to less than 10kg. The association between DJD and the outcome wasn’t statistically significant in dogs 1 to 5 years in both weights. In elder dogs, weight wasn’t a main factor, and association between DJD and outcome was statistically significant in both weights. In latter group, DJD had effective role on the outcome in dogs less than 10 kg in comparison with more than 10 kg. The authors suggest the weight is not as much effective as age among groups of study after Excision arthroplasty of the hip joint.
