Radiographic Assessment of Epiphyseal Plate Closure Time of Metacarpus and Phalanges in Goat Kids

Öz

In this study, we aimed to assess epiphyseal plate closure time of metacarpus, first and second phalanges, growing amount in the related bones and effect of gender on epiphyseal plate closure time. The study was carried out on 30 yeanlings, 15 males and 15 females. Each month DP radiographs were taken until the epiphyseal plate closures in related bones were completed (24 months). Bone radiographs were measured on negatoscope and values were recorded. At 12^th month, average lengths of first phalanges were measured as 36.05 ± 1.57 mm in females and 36.40 ± 1.67 mm in males; the average length of second phalanges was measured as 24.01 ± 1.83 mm and 24.16 ± 1.32 mm. The average metacarpus lengths were measured as 104.00 ± 3.56 mm in females at the 23^rd month and 104.85 ± 2.75 mm in males at the 24^th month. Epiphyseal plates were open during first 5 months in both males and females; between 5^th and 6^th months they began to close. Complete closure of the distal epiphyseal plates in females was completed between 20^th and 23^rd months, and between 21^st and 24^th months in males. In both genders, the proximal epiphyseal plates of the 1^st and 2^nd phalanges began to close between 5^th and 6^th months, and the complete closure occurred between 10^th and 12^th months. As a result, some determinations were obtained: metacarpal growth occurred distally; nevertheless, growth of 1^st and 2^nd phalanges occurred from proximally; gender has no effect on the bones; the distal epiphyseal plates of metacarpus were closed between 20^th and 23^rd months in the females and 21-24^th months in males; the proximal epiphyseal plates of the first and second phalanges were closed between the 10^th and 12^th months in both genders.

Oğlaklarda Metakarpus ve Falanksların Epifiz Plaklarının Kapanma Sürelerinin Radyografi ile Belirlenmesi

Öz

Bu çalışmada; tiftik keçisi oğlaklarında metakarpus ile 1 ve 2. falanksların epifiz plaklarının kapanma sürelerinin radyografiyle tespiti, aylara göre ilgili kemiklerdeki uzamalar ve cinsiyetin kapanma üzerine etkisinin belirlenmesi amaçlandı. Çalışma 15 erkek 15 dişi olmak üzere toplam 30 oğlakta gerçekleştirildi. Oğlakların ilgili kemiklerindeki epifiz plaklarının kapanması tamamlanıncaya kadar (24 ay), her ay D/P pozisyonda radyografileri çekildi. Radyografileri alınan kemiklerin uzunlukları negatoskop üzerinde ölçülerek kaydedildi. Radyogramlar üzerinden yapılan kemik uzunluğu ölçümlerinde; 12. ayda 1. falanks dişilerde ortalama 36.05 ± 1.57 mm, erkeklerde ortalama 36.40 ±1.67 mm, 2. falanks dişilerde ortalama 24.01 ± 1.83 mm erkeklerde ortalama 24.16 ± 1.32 mm olarak belirlendi. Metakarpus uzunluğu, dişilerde 23. ayda ortalama 104.00 ± 3.56 mm, erkeklerde 24. ayda ortalama 104.85 ± 2.75 mm olarak saptandı. Dişi ve erkek oğlaklarda ilk 5 ay boyunca metakarpusun distal epifiz plakları açıkken 6 - 8. aylar arasında kapanmaya başladılar. Dişilerde distal epifiz plaklarının tamamen kapanması 20 - 23. aylar arasında tamamlanırken, erkeklerde ise 21 - 24. aylar arasında gerçekleşti. Her iki cinsiyette de 1 ve 2. falanksın proksimal epifiz plakları 5 - 6. aylar arasında kapanmaya başlarken,  tamamen kapanmaları ise 10 - 12. aylar arasında gerçekleşti.  Sonuç olarak, tiftik keçilerinde metakarpusun distalden, 1 ve 2. falanksların ise proksimalden uzunlamasına büyüdüğü, cinsiyetler arasında her üç kemik uzunluğu için de önemli bir fark olmadığı, metakarpusun distal epifiz plağı dişilerde 20 - 23., erkeklerde ise 21 - 24. aylar, 1 ve 2. falanksın proksimal epifiz plaklarının ise  her iki cinsiyette de 10 - 12. aylar arasında  kapandığı saptandı.
