Dimensions and pattern of growth of the femoropatellar groove: A digital metric study on adult and fetal femora

Abstract

Objectives: A detailed knowledge about the anatomy of the

femoropatellar groove (FPG) and its articulation is essential for the

better understanding of the patellar stability. Therefore, the present

study was carried out to describe the morphology of FPG in adults

and the pattern of its growth in fetuses.

Materials and Methods: Thirty-seven adult dry femora of

unknown age and 24 fetal femora of known gestational age were

included in the study. The dimensions of FPG and its angulations

were calculated digitally using Image J software and were analyzed

statistically.

Results: The femoropatellar angulation ranged from 136.38°

to 142.38°. The dimensions and angulation were correlated with

the gestational age. The dimensions of FPG and the altitude of

lower end of the femur increased significantly with the gestational

age (P<0.05). There was also a significant negative correlation

between the femoropatellar angulation and the gestational age

(P<0.05).

Conclusion: This study provides a database for the parameters

of the adult femora. It also describes the pattern of growth of

the lower end of fetal femur. These findings are essential in

determining the patellar stability during walking.

Femoropatellar oluk boyutları ve büyüme paterni: Erişkin ve fetal femoral kemik üzerinde dijital metrik bir çalışma

Abstract

Amaç: Femoropatellar oluğun ve eklemlerinin anatomisinin detaylı

bir şekilde bilinmesi, patellar stabilitenin daha iyi anlaşılmasını

sağlar. Bu nedenle, bu çalışma yetişkinlerde FPG morfolojisini ve

fetüslerde büyümenin paternini tanımlamak için yapılmıştır.

Gereçler ve Yöntemler: Çalışmaya, yaşları bilinmeyen 37

erişkin kuru femur ve 24 gestational yaşı bilinen fetal femur dahil

edildi. Femur ve angülasyonlarının boyutları Image J yazılımı

kullanılarak dijital olarak hesaplandı ve istatistiksel olarak analiz

edildi.

Bulgular: Femoropatellar angülasyon 136.38 ° ila 142.38 °

arasındaydı. Boyutlar ve angülasyon gebelik yaşı ile korelasyon

göstermektedir. FPG’nin boyutları ve femurun alt ucunun

yüksekliği, gebelik haftası ile anlamlı olarak artmıştır (P<0.05).

Ayrıca, femoropatellar angülasyon ile gestasyonel yaş arasında

anlamlı negatif korelasyon saptanmıştır (P<0.05).

Sonuç: Bu çalışma yetişkin femur parametreleri için bir

veritabanı sağlar. Bu aynı zamanda fetal femurun alt ucunun

büyüme paternini de açıklar. Bu bulgular, yürüme sırasında patellar

stabiliteyi belirlemede esastır.
