Abstract

Amaç: Bu çalışmanın amacı adli kemik yaşı tayininde iliyak krestin çok
kesitli bilgisayarlı tomografi (ÇKBT) ile değerlendirilmesi ve kemik yaşı
tayininde beşli derecelendirme sistemi olarak kullanılan Schmeling Metodu’nun,
ÇKBT eşliğinde iliyak kreste uygulanabilirliğinin araştırılmasıdır.

Yöntem: Kliniğimizde daha önce çeşitli sebeplerle elde edilen 10-30 yaşları
arasındaki 551 bireye ait alt abdomen bilgisayarlı tomografi tetkiki
değerlendirildi.  Beşli evreleme
sistemine göre evre 4’de apofizyal skar fluluk şeklinde ve belli belirsiz, sığ,
ince bir çentik şeklinde izlenmekte iken evre 5’te ossifikasyon tamamlanmış
olup, skar hiçbir kesitte izlenmemekteydi.

Bulgular:
En erken görülme yaşları evre 2’de,
erkeklerde 11.5, kızlarda 11.6, evre 3’te erkeklerde 14.3 kızlarda 13.4, evre
4’te erkeklerde 17.4, kızlarda 16.5 ve evre 5’te her iki cinsiyet için 18
olarak bulunmuştur.

Sonuç:
Önceki çalışmalarda illiyak krest için
kullanılan dörtlü evreleme sistemine göre son evrenin en erken görülme yaşı 17
olmasına karşın, mevcut çalışmada beşli evreleme sistemine göre 5. evrenin her
iki cinsiyette en erken görülme yaşı 18 olarak belirlenmiştir ve elde edilen
bulgular, iliyak kemik ile adli yaş tayininde 18 yaş sınırını belirlemek
amacıyla beşli evreleme sisteminin, dörtlü evreleme sistemine göre daha
avantajlı olabileceğini göstermektedir.

The role of multidetector computed tomography of the iliac crest in forensic age estimation

Abstract

Objective: The aim of the present study
is to evaluate the iliac bone for skeletal age assessment and to determine
whether Schmeling methods are applicable to the evaluation of iliac crest
maturation by multidetector computed tomography (MDCT). 

Method: 551 individuals ranginig in
age 10-30 years who previously underwent abdominal CT examinations at various
occasions in our clinic. At 5-stage method; 
criteria for stage 4 are that the apophyseal
scar is seen as a unsharp image, or appears as an indistinct, shallow, thin
notch and criteria for stage 5 are apophyseal
cartilage fully ossified, apophyseal scar no longer visible.

Results: Based on the 5-stage method,
the earliest ages for stage 2 are at 11.5 years in boys and 11.6 years in
girls; for stage 3, 14.3 in boys and13.4 years in girls; for stage 4, 17.4
years in boys and 16.5 years in girls; for stage 5, 18 years for both sexes.

Conclusion: Although the earliest age of
last stage was 17 according to the 4-stage method in previous studies, the
earliest age of the 5-stage method was determined to be 18 according to the the
present study. These results show that the 5-staging system may be more
advantageous than the 4-staging system in order to determine the 18-year age
limit in forensic age assessment using the iliac crest.
