Objective & Hypothesis:Introduction: This study is an experimental setup to examinethe effects of splenectomy, applied to multi-trauma patientswho are commonly seen in emergency traumatologypractices and on fracture healing processes with respect tohistopathological, biomechanical, and radiological aspects.Methods: Further, 32 male Sprague Dawley rats (10 monthsold; average weight 394.5±28.3 g) are included in the study.In a dark environment, rats are fed at 22 °C for 12 hourswith standard rodent food ad libitum.

Abstract

Introduction: This study is an experimental setup to examinethe effects of splenectomy, applied to multi-trauma patientswho are commonly seen in emergency traumatologypractices and on fracture healing processes with respect tohistopathological, biomechanical, and radiological aspects.Methods: Further, 32 male Sprague Dawley rats (10 monthsold; average weight 394.5±28.3 g) are included in the study.In a dark environment, rats are fed at 22 °C for 12 hourswith standard rodent food ad libitum. They are divided intotwo groups: splenectomy (total splenectomy and long bonefracture healing) and control (only long bone fracture healingn=16). Four months after surgery, rats are killed, and callustissues in fractured femurs were examined histopathologically,radiologically, and biomechanically.Results: In the radiological analysis of the femur materialsin relation to the case and control groups, there was nosubstantial difference in the Goldberg classification score(p˃0.05). Similarly, no substantial difference was observed(p˃0.05) in histopathological examinations and biomechanicalanalysis conducted in femur samples.Conclusion: When all of the results obtained in our studyare evaluated together, it was concluded in the rats to whichsplenectomy is applied that this did not affect fracture healinghistopathologically, biomechanically, and radiologically,despite the modification of immune modulators.

Özet

Amaç: Bu çalışma acil travmatoloji pratiğinde sıkça görülen bir durum olan multi travma hastalarında yapılan splenektominin kırık iyileşme sürecine olan etkilerini histopatolojik, biyomekanik ve radyolojik açıdan incelemek için oluşturulmuş bir deneysel düzenektir. Yöntemler: Çalışmaya 32 erkek Sprague Dawley rat alındı (10 aylık; ortalama ağırlık, 394,5±28,3 g). Sıçanlar, karanlık bir ortamda 12 saat boyunca 22 °C’de standart kemirgen gıda ad libitumu ile beslendi. Splenektomi (toplam splenektomi ve uzun kemik kırık iyileşmesi) ve kontrol grubu (sadece uzun kemik kırık iyileşmesi n=16) olmak üzere iki gruba ayrıldı. Ameliyattan dört hafta sonra, sıçanlar sakrifiye edildi ve kırılan femurlarındaki kallus dokuları histopatolojik, radyolojik ve biyomekanik olarak incelendi. Bulgular: Olgu ve kontrol grubunda gönderilen femur materyallerinin radyolojik incelemesinde yapılan Goldberg sınıflama skorlamasında anlamlı (p˃0,05) farklılık göstermemiştir. Yine gönderilen femur numunelerinde yapılan histopatolojik incelemeler ve biyomekaniksel analizlerde de anlamlı (p˃0,05) farklılık gösterilememiştir. Sonuç: Çalışmamızdan elde edilen tüm sonuçlar birlikte değerlendirildiğinde splenektomi yapılan sıçanlarda immün modülatörler üzerinde oluşturduğu modifikasyon değişikliğine rağmen kırık iyileşmesini histopatolojik, biyomekanik ve radyolojik olarak etkilemediği sonucuna varılmıştır.
