The aim of the present study is to report the use of semicircular external skeletal fixator-intramedullary pin tie-in configurations for management of femoral fractures in dogs. Twenty dogs (21 femoral fractures) with complete clinical and radiographic records for at least 24 weeks were included in the study. A unilateral, multiplanar, semicircular external skeletal fixator system was used in combination with intramedullary pin. Fracture description, history, frame configuration, complications, limb use, concomitant injury, fixator removal time, and functional outcome were evaluated. All of the fractures with sufficient follow up were healed. Eight dogs started to use the operated limb immediately after recovery from anaesthesia whereas initial limb use was 1 to 7 days in other dogs. Time for removal of the fixator ranged from 36 to 67 days (mean, 50 days). Functional outcome was excellent in 15 cases, good in 4 cases, fair in 1 case and poor in 1 case. As a result, it was concluded that semicircular external skeletal fixator intramedullary pin tie-in configurations can be used as an alternative for the management of the femoral fractures in dogs

Bu çalışmanın amacı köpek femur kırıklarının sağaltımında semisirküler eksternal fiksatör intramedullar pin tie-in kombinasyonu ile ilgili sonuçların sunulmasıdır. Çalışmada en az 24 haftalık klinik kaydı ve radyografik verisi bulunan 20 köpek (21 femur) yer aldı. Unilateral, multiplanar, semisirküler eksternal fiksasyon sistemi ile intramedullar pin kombinasyonu kullanıldı. Kırığın tipi, anamnez, çerçevenin konfigürasyonu, komplikasyonlar, bacağın kullanımı, eşlik eden lezyon, fiksatörün çıkarılma zamanı ve sonuçlar değerlendirildi. Bütün kırıklarda kaynama şekillendi. Sekiz olgu operasyondan hemen sonra ilgili bacağını kullanmaya başlarken diğer olgularda bu sürenin 1 ile 7 gün arasında değiştiği gözlendi. Fiksatörün uzaklaştırılma süresi 36 ila 67 gün (ortalama, 50 gün) arasında değişim gösterdi. Fonksiyonel değerlendirme, olguların 15’inde mükemmel, 4’ünde iyi, 1’inde orta ve 1’inde ise zayıf olarak değerlendirildi. Sonuç olarak, semisirküler eksternal fiksasyon intramedullar pin tie-in konfigürasyonunun, köpeklerin femur kırıklarında bir alternatif sağaltım yöntemi olarak kullanılabileceği kanısına varılmıştır
