ÖZAmaç: Bu çalışmada beş farklı türde kortikal vida, eşdeğer test koşulları altında yapay femurlar kullanılarak değerlendirildi. Gereç ve yöntemler: Dördüncü jenerasyon kompozit femurlar kullanılarak kemik-vida arayüzünde deformasyon için gerekli olan maksimum yük, her bir vida türü için ayrı ayrı çekme deneyi yapılarak incelendi. Elde edilen sonuçlar geleneksel yöntemler ve çapraz karşılaştırma ile normalize edildi. Çekme testlerini vida boyutlarına bağlı olarak yapmak için bikortikal kemik kalınlığının etkisi, vida yerleştirme şartları eşitlenerek ortadan kaldırıldı. Bulgular: Büyük çaplı ve derin hatveli kilitsiz vidaların yerinden çıkması için daha büyük çekme kuvveti gerekti; bu vidalar daha küçük boyutlu kilitli vidalarla karşılaştırıldığında istatistiksel olarak daha üstün performans gösterdi. Bununla birlikte, saf çekme yükleri arasındaki istatistiksel farklılıklar, sonuçların geleneksel normalizasyonundan sonra azaldı. Katı geometrik akıl yürütmeye bağlı olarak yeni bir normalizasyon yöntemi önerildi. Sonuç: Bu yeni yaklaşım, ortalama performans gösteriyor gibi görünen bir vida türünün aslında en iyi performans gösterenlerden istatistiksel olarak anlamlı farklı sonuçlara sahip olmadığını ortaya koydu. Cerrahlar küçük boyutlu konak kemiklerde daha büyük boyutlu vidaları tercih etmek zorunda değildirler.Anahtar sözcükler: Biyomekanik karşılaştırma; kortikal vidalar; çekme gücü. ABSTRACTObjectives: This study aims to assess five different cortical screw types using artificial femurs, under equated testing conditions. Materials and methods: We investigated the maximum force needed to cause deformation at screw-bone interface using fourth generation composite femurs by conducting separate pullout tests for each screw type. We normalized obtained results with traditional methods and crosscomparison. To conduct pullout tests dependent on screw dimensions, we eliminated the effect of bicortical bone thickness by equalizing the conditions of screw insertion. Results: Non-locking screws with larger diameter and pitch depth required larger pullout forces to be extracted, showing statistically superior performance compared to locking screws with smaller dimensions. However, the statistical differences between the absolute pullout forces decreased after the traditional normalization of the results. We proposed a new normalization method based on solid geometric reasoning. Conclusion: This novel approach showed that a screw type that appeared to show average performance, in fact, did not have statistically significantly different results than the top performers. Surgeons are not required to prefer larger dimension screws in small dimension host bones.

Klinische Ergebnisse nach konservativer und operativer Therapie der distalen Radiusfraktur beim älteren Patienten

Fractures of the distal radius in elderly patients increasingly contribute to the workload in emergency departments worldwide. There is still no consensus about the best treatment option, e. g. closed reduction and cast stabilization, percutaneous pinning, external fixation or open reduction and internal fixation with volar locking plates (ORIF). In addition, the influence of pharmacological antiosteoporotic treatment (e. g. bisphosphonates) is unclear. In this overview five comparative studies were analyzed, which had been identified in a previous systematic review. The evaluation included 3 cohort studies and 2 randomized trials enrolling a total of 515 patients. A clinical or statistical advantage of ORIF over conservative treatment with respect to DASH scores 12 months after the index fracture event could not be demonstrated with a mean difference of 0.25 (95 % confidence interval CI -0.57-1.07). According to current best scientific evidence from preclinical and clinical investigations, antiosteoporotic medication does not have an unfavorable influence on fracture healing and should be continued due to its proven effectiveness in reducing subsequent osteoporotic fractures. Following distal radius fractures in elderly patients with clinical risk factors, an osteoporosis screening should be routine practice and a specific therapy should be initiated if the fracture risk is increased.
