角度, angle,  角, vinkel, มุม, Winkel, ángulo, úhel, ......

With the growth of living creatures, there are many kinds of golden criterias that define the average standard angle for every part of our body.

• Baumann angle: 經過外側髁骺板的斜線與肱骨幹中軸線的夾角
• Q-angle: 股四頭肌角度
• Sulcus angle: 股骨凹溝角度
• Patella tilt angle: 髕骨傾角
• Roof arc angle: 

Draw a vertical line through the rotational centre of the acetabulum. Draw a second line through the rotational centre of the acetabulum to the point where the fracture crosses the radiographic dome. 

The roof-arc angle is the angle created where these lines cross.

• Carrying angle is a small degree of cubitus valgus, formed between the axis of a radially deviated forearm and the axis of the humerus. It helps the arms to swing without hitting the hips while walking. Normally it is 5-15o away from the body or 165-175o towards the body. A decreased carrying angle can result in the forearm pointing towards the body, known as gunstock deformity or cubitus varus.
• Cobb's angle: 定義脊椎側彎的嚴重程度。
