Influence of Initial Displacement on Union in Collum Femoris Fractures

Öz

Many factors affect the union of the fracture in collum femoris fractures in adults. We aimed to examine the relationship between the preoperative displacement, the postoperative displacement, and the preoperative waiting time with the union of the fracture. The present study was carried out retrospectively with 52 patients. The patients were divided into three groups according to the union time. Fracture union took 12 weeks or less constituted Group 1 (n=25), patients with the union over 12 weeks constituted Group 2 (n=19), and patients with nonunion formed Group 3 (n=8). Computed tomography was used for the preoperative measurements, and postoperative displacement measurements were made with X-ray.There was no statistically significant difference between the 3 groups regarding the preoperative waiting time and postoperative displacement. While there was no statistically significant difference between Groups 1 and 3, and Groups 2 and 3 for preoperative displacement, the difference was statistically significant in the comparison of Groups 1 and 2 (p=0.046). Between Groups 1 and 2, it was observed with 78.3% accuracy, 73.7% sensitivity, and 72% specificity that there was delayed union in patients with the preoperative displacement of 9.5 mm and above.In the present study, in which the relationship between initial displacement, postoperative displacement, and preoperative waiting time with the fracture union was examined, it was concluded that delayed fracture union could occur when the initial displacement is more than 9.5 mm.

Femur Boyun Kırıklarında Başlangıç Deplasmanının Kırık Kaynamasındaki Önemi

Öz

Erişkin kollum femoris kırıklarında birçok faktör kırığın kaynamasını etkiler. Bu çalışmada preoperatif deplasman miktarı, postoperatif deplasman miktarı ve ameliyat öncesi bekleme süresi ile kırık kaynaması arasındaki ilişkiyi incelemeyi amaçladık. Çalışma retrospektif olarak 52 hasta ile gerçekleştirildi. Hastalar kaynama zamanına göre üç gruba ayrıldı. 12 hafta ve daha kısa sürede kaynama olan hastalar Grup 1 (n=25), kaynama süresi 12 haftayı geçen hastalar Grup 2 (n=19), kaynamayan hastalar Grup 3 (n=8) olarak belirlendi. Ameliyat öncesi ölçümlerde bilgisayarlı tomografi, ameliyat sonrası yer değiştirme ölçümleri ise direk grafi ile yapıldı.Preoperatif bekleme süresi ve postoperatif deplasman bakımından 3 grup arasında istatistiksel olarak anlamlı fark yoktu. Preoperatif deplasman açısından Grup 1 ve 3 ile Grup 2 ve 3 arasında istatistiksel olarak anlamlı fark bulunmazken, Grup 1 ve 2 karşılaştırıldığında fark istatistiksel olarak anlamlı bulundu (p=0,046). Grup 1 ve 2 arasındaki değerlendirmede preoperatif deplasmanın 9,5 mm ve üzerinde olan hastalarda %78,3 doğruluk, %73,7 duyarlılık ve %72 özgüllük ile kaynamada gecikme olduğu görüldü. Kırık kaynaması ile başlangıç deplasmanı, postoperatif deplasman ve ameliyat öncesi bekleme süresi arasındaki ilişkinin incelendiği bu çalışmada başlangıç deplasmanının 9,5 mm'den daha fazla olduğu kollum femoris kırıklarında kırık kaynamasının geçiktiği görüldü.
