FETAL DÖNEMDE FEMUR DİSTALİNİN MORFOMETRİK GELİŞİMİ

Amac. Calismamizda fetal donem boyunca femurun distalinde yer alan olusumlarin morfometrik degisimi ve gelisiminin arastirilmasi amaclandi. Gerec ve Yontem: Yaslari 9-40 hafta arasinda degisen eksternal anomalisi ve patolojisi olmayan 105 (55erkek, 50 kiz) adet insan fetusunda calisildi. Fetuslar I.grup; 9-12 hafta, II. grup; 13-25 hafta, III. grup; 26-37 hafta ve IV. grup; miadinda, 38-40 hafta olmak uzere 4 gruba ayrildi. Butun fetal materyallerde diz eklemi diseke edilerek patella ve patellar tendon yerinden kaldirildi ve femur distaline ait fossa intercondylaris yuksekligi, genisligi, condylus medialis yuksekligi ve genisligi, condylus lateralis yuksekligi ve genisligi, femur distalinin genisligi, trohlear oluk acisi olcumleri alindi. Bulgular: Fossa intercondylaris yuksekligi ve genisligi gestasyonel yas boyunca artiyordu ve trimesterlar arasinda anlamli fark vardi (p<0.05). Femur distalindeki medial ve lateral kondillerin yukseklik ve genisliklerinin gestasyonel yas boyunca arttigi goruldu (p<0.05). Lateral kondil yuksekliginin ve genisliginin medial kondil yukseklik ve genisliginden daha buyuk oldugu tespit edildi (p<0.05). Patellar oluk acisi ise gestasyonel yas boyunca degismiyordu ve ortalama 129. 9 derece idi. Ayrica calismamizda fetal donemde fossa intercondylaris sekil indeksi (notch shape index) (NSI) 0,91, fossa intecondylaris genislik indeksi (notch width index) (NWI) 0.26 olarak tespit edildi. Sonuc: Calismamizda elde edilen verilerin intrauterin olgularda femur gelisiminin degerlendirilmesine katkida bulunacagini dusunmekteyiz.

Materials and method: 105 human fetuses (55 males and 50 females) aged between 9-40 weeks were used in this study. Fetuses were divided into four groups between gestational weeks; 1st trimester (9-12 weeks), 2nd trimester (13-25 weeks), 3rd trimester (26-37 weeks) and full term (38-40 weeks). Patella and patellar tendon were dissected in all fetal materials and the knee of each fetus was shown. The dimensions; length and width of intercondylar notch, length and width of medial and lateral condyles, total width of the distal femur and the angle of trochlear groove were measured by Vernier's caliper and square. Finding: The length and width of fossa intercondylaris were found significantly different between trimesters and were rising with gestational age (p<0.05). The length and width of medial and lateral condyles were increased with gestational age. The length and width of lateral condyles were higher than the medial one. The angle of trochlear groove was not changing with gestational age and was found 129.90. It was also found in our study that notch shape index (NSI) was 0,91 and notch width index (NWI) was 0.26 during the fetal period. Result: We consider that the data acquired in our study may contribute to the evaluation the development of distal femur in intrauterine cases.
