İnsan Fetuslarinda Ligamentum Cruciatum Posterior’un Anatomik İncelemesi

Abstract

Amaç: Bu çalışmanın amacı insan fetüslerinde ligamentum cruciatum posterior (PCL) anterolateral bant (ALB) ve posteromedial bantlarının (PMB) varlığını, ayrımını ve morfolojik özelliklerini belirlemek ve PCL’nin haritalamasını yapmaktır.
Materyal ve Yöntemler: Çalışma gestasyonel yaşları 13-25 gebelik haftası arasında değişen, harici patolojisi ve anomalisi olmayan 40 fetal diz üzerinde gerçekleştirildi. Dizler tam fleksiyon pozisyonunda iken ALB ve PMB ayrımı yapılarak; PCL, ALB ve PMB’ın origo ve insertioları, orta genişlikleri ve uzunluklarının morfometrik ölçümleri yapıldı. Veriler hem tanımlayıcı hem de nicel istatistiksel yöntemlerle analiz edildi.
Bulgular: ALB’ye ait ölçümlerde sağ ve sol taraf parametreleri tüm fetüslerde değerlendirildiğinde ALB’nin proksimal genişlik ölçümünde anlamlı farklılık olduğu belirlendi (p<0.05). PCL’nin sağ ve sol taraflar arasında; distal genişlik (r=0,668; p=0,001), proksimal genişlik (r=0,849; p<0.001) ve uzunluk ölçümleri (r=0,795; p<0.001) arasında güçlü bir korelasyon saptandı. Sağ ve sol taraflar arasında, ALB'nin proksimal genişliği (r=0,758; p<0,001), orta nokta genişliği (r=0,832; p<0,001) ve uzunluk (r=0,691; p=0,001) dahil tüm ALB ölçümleri arasında güçlü bir korelasyon bulundu (p=0,001). Ayrıca sağ ve sol taraflar arasında PMB'nin proksimal genişliği (r=0,645; p=0,005) ve uzunluk (r=0,675; p=0,001) ölçümleri arasında güçlü bir korelasyon saptandı.
Sonuç: Fetal dönemde PCL’nin ve bantlarının özellikleri hakkında geniş bir haritalama elde edilmiştir.

Anatomical Examination of The Ligamentum Cruciatum Posterior in Human Fetus

Abstract

Objective: The aim of this study is to determine the presence, differentiation and morphological features of the anterolateral band (ALB) and posteromedial bands (PMB) of the ligamentum cruciatum posterior (PCL) in human fetuses and to map PCL.

Materials and Methods: The study was carried out on 40 fetal knees with gestational ages ranging from 13 to 25 weeks of gestation without any external pathology or anomaly. ALB and PMB distinction was made when the knees were in full flexion position, and morphometric measurements of origo and insertio, mid width and length of PCL, ALB and PMB were made. Data were analyzed with both descriptive and quantitative statistical methods.

Results: When the right and left side parameters were evaluated in all fetuses in the measurements of ALB, it was determined that there was a significant difference in the proximal width measurement of ALB (p<0.05). There was a strong correlation between right and left sides of PCL, distal width (r=0.668; p=0.001), proximal width (r=0.849; p<0.001) and length measurements (r=0.795; p<0.001). A strong correlation was found between the right and left sides and the proximal width of the ALB (r=0.758; p<0.001), midpoint width (r=0.832; p<0.001) and length (r=0.691; p=0.001) measurements (p=0.001). In addition, a strong correlation was found between the measurements of the proximal width (r=0.645; p=0.005) and length (r=0.675; p=0.001) of the PMB between the right and left sides.

Conclusion: A broad mapping was obtained about the characteristics of PCL and its bands in the fetal period.
