Abstract

Kırıklar, özellikle elde meydana geldiğinde, günlük yaşamın kalitesini önemli ölçüde etkileyen travmalardan biridir. Metakarpal kırıklar, en yaygın el kırıkları arasında yer alır ve bunların etkin bir şekilde tedavi edilmesiyle elin normal işlevinin geri kazanılması açısından kritik öneme sahiptir. Bu çalışma, metakarpal eklem içi baş kırıklarının tedavisinde kullanılan kilitli plak, Kirschner teli ve bu iki yöntemin kombinasyonunun sonlu elemanlar yöntemi ile analiz edilmesini hedeflemektedir. Bu çalışmada el travması geçiren bir bireyin bilgisayarlı tomografi verileri kullanılarak üç boyutlu bir metakarpal kemik modeli ve kırık hattı oluşturulmuştur. Üç farklı tedavi için oluşturulmuş modellerin sonlu elemanlar esaslı analizi yapılmıştır ve analizlerinden elde edilen eşdeğer gerilme sonuçları değerlendirilmiştir. Elde edilen bulgular kilitli plak ve iki çapraz Kirschner teli kombinasyonunun diğer iki metoda kıyasla daha düşük gerilme değeri verdiğini göstermektedir. Bu sonuç, kombinasyon yönteminin kilitli plakaya göre nispeten daha stabil bir yapı sağladığını ortaya koymaktadır. Ayrıca, yalnızca Kirschner teli kullanılan yöntemin ise incelenen üç metod içinde en yüksek gerilme değerine sahip olduğu tespit edilmiş, bu da onun en az stabil yöntem olduğunu göstermektedir. Bu bulgular neticesinde, metakarpal eklem içi baş kırıklarının tedavisinde kilitli plak ve iki çapraz Kirschner teli kombinasyonunun kullanılmasının daha etkin olduğu sonucuna varılmıştır.

Finite element analysis of locked plate, two crossed K-wires, and combined application of both methods in intra-articular metacarpal head fractures

Abstract

Fractures, especially when they occur in hand, are one of the traumas that significantly affect the quality of daily life. Metacarpal fractures are among the most common types of hand fractures, and it is essential to treat them effectively to restore normal hand function. This study uses the finite element method to analyze the effectiveness of locked plates, Kirschner wires, and a combination of both in treating intra-articular metacarpal head fractures. Using computed tomography data from an individual who suffered hand trauma, a three-dimensional metacarpal bone model and fracture line were created. Finite element-based analyses were conducted for models created for three different treatments, and the equivalent stress results obtained from the analyses were evaluated. The findings indicate that combining a locking plate and two crossed Kirschner wires produces lower stress values than the other two methods. This result demonstrates that the combined method provides relatively greater stability than the locking plate alone. Additionally, the method using only the Kirschner wire was found to have the highest stress values among the three methods examined, indicating it is the least stable method. Consequently, it has been concluded that the combination of a locking plate and two crossed Kirschner wires is more effective for the treatment of intra-articular metacarpal head fractures.
