Abstract

Objectives: This study aims to compare non-compression and compression intramedullary nailing in an experimental femoral shaft osteotomy model in terms of radiological, histological, and biomechanical aspects.Materials and methods: Twenty-four white New Zealand rabbits (average weight 4.3 kg; range 4 to 4.8 kg) were divided into three groups. A right femoral osteotomy was performed in all rabbits and all femurs were fixed with titanium compression interlocking intramedullary nail. After locking of nails, no compression was performed in group 1 while 0.5 mm and 1 mm compressions were performed in group 2 and 3, respectively. All rabbits were sacrificed four weeks after operation. Fracture sites were examined histologically and radiologically. Finite element analyses were performed.Results: Radiological scores of groups 2 and 3 were significantly higher than group 1. There was no significant difference between groups 2 and 3 radiologically. Best histological scores were achieved in group 2. According to finite element analyses, osteotomy site in group 2 was exposed to 1240 N of load and 34.5 MPa of mean stress.Conclusion: Compression interlocking intramedullary nailing provides faster fracture healing than non-compression interlocking intramedullary nailing. Best histological fracture healing scores were obtained with 0.5 mm compression performed at the fracture site

Özet

Amaç: Bu çalışmada deneysel femur cisim osteotomisi modelinde kompresyonsuz ve kompresyonlu intramedüller çivileme radyolojik, histopatolojik ve biyomekanik açıdan karşılaştırıldı.Gereç ve yöntemler: Yirmi dört beyaz Yeni Zelanda tavşanı (ort. ağırlık 4.3 kg; dağılım 4-4.8 kg) üç gruba ayrıldı. Bütün tavşanlara sağ femur osteotomisi uygulandı ve tüm femurlar titanyum kompresyonlu kilitli intramedüller çivi ile tespit edildi. Çivilerin kilitlenmesinden sonra grup 1'e kompresyon uygulanmazken grup 2 ve 3'e sırasıyla 0.5 mm ve 1 mm kompresyon uygulandı. Cerrahiden dört hafta sonra bütün tavşanlar sakrifiye edildi. Kırık bölgesi histolojik ve radyolojik olarak incelendi. Sonlu eleman analizleri uygulandı.Bulgular: Grup 2 ve 3'ün radyolojik skorları grup 1'e kıyasla anlamlı derecede daha yüksekti. Grup 2 ve 3 arasında radyolojik olarak anlamlı farklılık yoktu. En iyi histolojik skorlar grup 2'de elde edildi. Sonlu eleman analizlerine göre grup 2'de osteotomi bölgesi 1240 N yüke ve 34.5 MPa ortalama basınca maruz kalmıştı.Sonuç: Kompresyonlu kilitli intramedüller çivileme, kompresyonsuz kilitli intramedüller çivilemeden daha hızlı kırık iyileşmesi sağladı. Histolojik olarak en iyi kırık iyileşmesi skorları kırık bölgesine uygulanan 0.5 mm kompresyon ile elde edildi
