Abstract

Aim: Mathematical
relationships between bones in close proximity are useful for determining the
proper length of comminuted or severely displaced bones during surgical
reconstruction. This study examined the relationship between the lengths of the
clavicle and ulna to develop a length propotion formula that can facilitate
obtaining the proper length of the clavicle during surgery for displaced and
comminuted fractures.

Methods:
The study enrolled 130 individuals (76 males, 54 females)who were healty for
their upper extremities and was seen in our orthopedics outpatient clinic
during April 2019 to June 2019. The right and left clavicles and ulnas of each
individual were measured. All measurements were peformed by two of the authors
in an blinded fashion.

 Results. Mean overall age was 32.2 years. There
were significant correlations between the clavicle and ipsilateral ulnar
lengths (p=0.001). However, there was a length difference between the right and
left clavicles. The left clavicle was 9.00 ± 2.16 mm longer than the right in
males and 7.13 ± 2.03 mm longer in females (p=0.001). There was no significant
length difference between the right and left ulnas in either sex (0.84 ± 1.033
mm in males and 0.52 ± 0.818 mm in females).

Conclusion.
There is a significant ratio between the clavicle and ulna lengths on both the
right and left sides in both sexes, but it isn’t the same for males and
females. We propose that these length proportion formula can be used for
determining the clavicle length for the surgical treatment of comminuted fractures
with plates and particularly with nails.

Klavikula ve ulna boyları arasında anlamlı bir oran varmı? Antropometrik ve istatistiksel bir çalışma

Abstract

Amaç:
Parçalı ve deplase kırıkların cerrahi rekonstrüksiyonu sırasında opere edilen
kemiğin uygun boyunun tahmin edilebilmesi için bu kemik boyu ile komşu diğer
bir kemiğin matematiksel olarak boy oranının kullanılması oldukça  kullanışlıdır. Bu çalışmada parçalı klavikula
kırıkları cerrahi tedavisi sırasında kullanılmak üzere, klavikula ve ulna
kemikleri arasında matematiksel olarak anlamlı bir boy oranı olup olmadığının
araştırılması amaçlanmıştır.

Yöntemler:
Nisan-Haziran 2019 dönemi içerisinde, ortopedi ve travmatoloji polikliniğimizde
görülen üst ekstremiteleri sağlıklı 130 hasta (76 erkek, 54 kadın) çalışmaya dahil
edildi. Bütün hastaların sağ ve sol ulna ve klavikulaları birbirinin
ölçümlerine kör 2 yazar tarafından, aynı yöntemler kullanılarak ölçüldü.

Bulgular:
Toplamda ortalama yaş 32.2 yıl idi. Aynı taraf ulna ve klavikula boyları
arasında anlamlı bir oran olduğu saptandı (p=0.001).  Aynı zamanda sağ ve sol klavikula boyları
arasında anlamlı uzunluk farkı bulunduğu görüldü. Sol klavikula, erkeklerde 9.00
± 2.16 mm ve kadınlarda 7.13 ± 2.03 mm sağ klavikuladan daha uzun idi (p=0.001).
Ancak her iki grupta da sağ ve sol ulna boyları arasında anlamlı bir fark
saptanmadı (0.84 ± 1.033 mm erkeklerde ve 0.52 ± 0.818 mm kadınlarda).

Sonuçlar:
Hem kadın, hem de erkeklerde her iki tarafta klavikula ve ulna kemikleri
arasında matematiksel olarak anlamlı bir oran var olduğu ortaya kondu. Ancak bu
oran her iki cinsiyet için farklı idi. Biz bu çalışmanın sonucuna dayanarak,
parçalı klavikula kırıklarının plak ve özellikle çivi ile cerrahi tedavisi
sırasında, ortaya konan bu orantısal formüllerin uygun kemik boyunun
hesaplanarak sağlanması için kullanılabileceğini düşünmekteyiz.
