Abstract

Purpose: Collum chirurgicum is the most frequently fractured part on the proximal humerus. While, collum fractures have been a subject to vast numbers of researches, its structural dispositions depending on the variants of sex and directional morphometry requires further investigation. Therefore, we aimed to evaluate sex and side differences by using morphometric measurements of humerus and collum chirurgicum.
Methods: In order to achieve the above-mentioned objective, measurements were performed on dry humerus specimens from 60 male and 60 female origins. The circumference of collum chirurgicum (CC) and humerus length (HL) were measured. After the completion of these measurements the area (CA) of collum chirurgicum was calculated and the data obtained was utilized to create two separate indexes.
Results: The circumference of collum chirurgicum differed significantly between the sexes, but not between the right-left sides. Although there was a significant difference between male and female HL on the right side, there was no significant difference on the left side. The highest mean value of the CC in females was lower than the minimum value obtained in males. The mean value of the CA in males was higher than the maximum value obtained in females. There was a significant difference between sexes for both indexes.
Conclusion: We think that collum chirurgicum is an important region in sex determination. Therefore, morphometric data of this area can shed light on forensic research and can give an idea about the approach to fracture treatment and help in solving the clinical problems that may occur.

Collum Chirurgicum'un Morfometrik Değerlendirilmesi

Abstract

Amaç: Collum chirurgicum, proksimal humerusta en sık kırılan bölümdür. Bu bölümün kırıkları çok sayıda araştırmaya konu olurken, cinsiyet ve taraf morfometrisinin varyantlarına bağlı yapısal eğilimleri daha fazla araştırma gerektirmektedir. Bu nedenle, humerus ve collum chirurgicum'un morfometrik ölçümlerini kullanarak cinsiyet ve taraf farklılıklarını değerlendirmeyi amaçladık.
Yöntemler: Bu nedenle, 60 erkek ve 60 kadın orijinli kuru humerus numuneleri üzerinde ölçümler yapıldı. Collum chirurgicum (CC) çevresi ve humerus uzunluğu (HL) ölçüldü. Bu ölçümler tamamlandıktan sonra collum chirurgicum alanı (CA) hesaplandı ve elde edilen veriler iki ayrı indeks oluşturmak için kullanıldı.
Bulgular: Collum chirurgicum'un çevresi cinsiyetler arasında önemli ölçüde farklılık gösterdi, ancak sağ-sol taraflar arasında değil. Sağ tarafta erkek ve kadın HL arasında anlamlı fark olmasına rağmen sol tarafta anlamlı bir fark yoktu. Kadınlarda CC'nin en yüksek ortalama değeri erkeklerde elde edilen CC'nin minimum değerinden daha düşüktü. Erkeklerde CA ortalama değeri kadınlarda elde edilen maksimum değerden daha yüksekti. Her iki indeks için cinsiyetler arasında anlamlı bir fark vardı.
Sonuçlar: Collum chirurgicum'un cinsiyet belirlemede önemli bir bölge olduğu kanısındayız. Bu nedenle, bu alanın morfometrik verilerinin adli araştırmalara ışık tutabileceğini, kırık tedavisinin yaklaşımında ve oluşabilecek klinik problemlerin çözümünde yardımcı olabileceğini düşünüyoruz.
