Abstract

Objectives: The incidence of femoral neck fractures in younger-age people increases due to high-energy trauma. To avoid complications, stable internal fixation is essential. The most commonly used implants for vertically oriented femoral neck fractures are the cannulated and dynamic hip screws. In our study, we compared differently oriented cannulated screw configurations and a standard DHS for fixation of femoral neck fracture.Materials and Methods: A finite element-based collum femoris fracture was created and was fixed using four differently oriented triangular screw configurations and a dynamic hip screw. The loads were applied using a commercially available software package.Results: Centrally oriented cannulated screw configuration had the most compression and compression stress on the fracture side, and it had the highest stress values on the implant.Conclusion: We recommend the use of centrally oriented triangular cannulated screws for femoral neck fracture fixation. With this construct, more compression and compression pressure can be obtained, which can result in the early healing of the fracture. However, it must be kept in mind that this construct exerts more stress on the implant, which could be a reason for implant failure

Özet

Amaç: Yüksek enerjili travma insidansındaki artış ile genç yaşlarda görülen femur boyun kırığı sayısında belirgin bir artma olmuştur. Komplikasyonlardan korunmak için, tedavide stabil internal fiksasyon ön koşuldur. Femur boyun kırıklarının cerrahi tedavisinde en sık kanule vidalar ve dinamik kalça çivileri kullanılmaktadır. Biz çalışmamızda değişik konfigurasyondaki kanule vida uygulamalarının ve dinamik kalça çivisinin stabilizasyonunu karşılaştırdık.Hastalar ve yöntemler : Çoklu eleman yazılımı ile femur boyun kırığı modellemesi yaratıldı. Ve kırık dört ayrı kanüle vida konfigirasyonu ya da dinamik kalça çivisi kullanılarak tespit edildi. Aksiyel yükleme yapılarak direnç ve dayanıklılık testleri uygulandı.Bulgular: Santral oryante kanüle vida konfigirasyonunun kırık hattında en iyi kompresyon sağlayan ve aksiyel yüklenme stresine en dayanıklı model olduğu ortaya kondu.Sonuç: Femur boyun kırıkları için santral konfigirasyonlu kanüle vida ile tespit yapılmasını önermekteyiz. Bu şekilde kırık hattında maksimum kompresyon sağlanarak, erken iyileşmeye de olanak sağlanmaktadır
