Yeni Zelanda Tavşanı’ında ön bacak eklemlerinin üç boyutlu kemik modellenmesi: Mikro Bilgisayarlı Tomografi çalışması

Bu çalışmada, deneysel ortopedik çalışmalarda sıklıkla tercih edilen Yeni Zelanda Tavşanı’nda sağlıklı ön bacak eklemlerinin mikro bilgisayarlı tomografi (μBT) tekniği ile elde edilen görüntülerinden 3B dijital modellerinin oluşturulması, modeller üzerinde omuz ile dirsek eklemlerine ait morfometrik ölçümlerin sağlanması ve bu modellerden 3B yazıcılar kullanılarak 3B baskı modellerinin üretilmesi amaçlanmıştır. Çalışmada toplamda 14 adet (7 dişi, 7 erkek) erişkin Yeni Zelanda Tavşanı kullanıldı. Ön bacakları μBT cihazı ile görüntülenip görüntülerden 3B dijital ve baskı modelleri elde edildi. 3B dijital modeller üzerinden omuz ile dirsek eklemlerine ait biyometrik ölçümleri gerçekleştirildi. Dişi ve erkek tavşanlara ait elde edilen veriler istatistiki açıdan değerlendirildi. Kesit kalınlığının düşük ve dedektör kalitesinin yüksek olması sebebiyle 3B eklem modellerindeki anatomik yapı oldukça detaylıydı. Üç boyutlu baskılama işlemi sonucunda üretilen 3B baskı modelleri son derece dayanıklı, kokusuz ve temizdi. 3B baskı modelleri ile 3B dijital modeller arasında herhangi bir anatomik farklılık gözlenmedi. Bu çalışmada laboratuvar tavşanlarına ait elde edilen anatomik ve morfometrik verilerin hem deneysel amaçlı ortopedik girişimlerde bulunan hem de klinik anatomi eğitimlerinde rol alan bilim insanlarına katkı sağlayacağı düşünülmektedir.

Three-dimensional bone modeling of forelimb joints in New Zealand Rabbit: A Micro-Computed Tomography study

In this study, it was aimed to obtain 3-dimensional (3D) digital and printed models of healthy forelimb joints using micro-computed tomography (µCT) technique in New Zealand Rabbit, which is frequently preferred in experimental orthopedic studies. Moreover, it was aimed to provide morphometric measurements on the shoulder and elbow joints over 3D digital models. A total of 14 adults (7 female, 7 male) New Zealand Rabbits were used in the study. After imaging the forelimbs with the µCT device, 3D digital and printed models were obtained. Biometric measurements of shoulder and elbow joints were performed over 3D digital models and the data obtained from female and male rabbits were evaluated statistically. The anatomical structure on the 3D joint models was very detailed due to the low section thickness and high detector quality. 3D printed models produced as a result of the 3D printing process were quite durable, odorless, and clean. No anatomical differences were observed between 3D printed models and 3D digital models. In this study, it is thought that the anatomical and morphometric data obtained from laboratory rabbits will contribute to scientists take part both in experimental orthopedic intervention and clinical anatomy education.
