한국 성인의 흉골에 대한 형태학적 연구

Abstract

[한글]

저자는 101례의 한국성인흉골을 그 형태하적 변형에 유의하여 관찰, 분석하였으며 다음과 같은 결과를 얻었다.

1. 흉골의 길이는 신장의 약 11%였으며 흉골병과 흉골체의 길이의 합은 신장의 약 9%였다. 흉골체의 길이는 흉골병 길이의 약 2배였다.

2. 흉골병과 흉골체 사이의 골성결합 빈도는 25.7%였으며 그 빈도의 남녀차는 뚜렷하지 않았고 연령과의 상관성도 찾을 수 없었다.

3. 흉골의 형태를 그 편향성에 따라 type Ⅰ (수직형), type Ⅱ(우편향형), type Ⅲ(좌편향형)으로 분류하였고 만곡이 동반될 경우 type A(우만곡형), type B(좌만곡형)로 그 야류를 분류하였다. 가장 흔한 형은 type Ⅰ(70.3%)이었으며 19례(18.8%)에서 만곡을 관

찰할 수 있었다.

4. 늑골절흔의 수는 7개인 경우가 가장 많았다 (우측:68.3%, 좌측:66.3%).

5. 골편은 32례(31.7%)에서 관찰할 수 있었으며 모두 늑골 관절함몰부에 위치하였고 그 모양이 기저선을 흉골쪽에 둔 예각삼각형이었다. 가장 흔한 부위는 양측 제 5늑골관절함

몰이었다.

Morphological Study of the Sternum of Korean adult

Seung Haeng Joo

Department of Medical Science, The Graduate School Yonsei University

(Directed by Prof. In Hyuk Chung, M.D.)

The sternum is a universal structure of the Vertebrate and it shows wide

interspecies and intraspeces variations. During early fetal life a anterior rostral

ruminant and two sternal bands make there appearance and were fused. Later it was

divided into three parts, munubrium, body and xiphoid.

101 cases of the sternum of Korean adult were reviewed and were analyed with a

caution of morphological variation. The results are summerized as follows:

1. The length of the sternum is about 11% of height and the length of manubrium

and body is about 9% of height. The length fo body is aout 2 times longer than the

length of namubrium.

2. The frequency of synostosis between manubrium and body is 25.7%. No remarkable

sexual difference and no correlation with age were demonstrated.

3. The types of the sternum were classified as type Ⅰ(straight type), type

Ⅱ(diviated to the right), type Ⅲ(deviated to the left) according to its

deviations. And when the curvature was present it was subclassified as type

A(cunvex to the right) and type B(convex to the left). The most common type is type

Ⅰ(70.3%) and in 19 cases(18.8$) the curvature was noted.

4. Total numbers of costal notches were seven in most cases(in the right; 68.3%

of total cases, in the left; 66.3% of total cases).

5. The osteophytes are noted in 32 cases(31.7%). They are all located in the

costal notch costal notch and show sharp triangle with its base in costal notch.

The most common site of the osteophytes are the 5th costal notches of both side.
