Glenopolar angle
Glenopolar angle is a term used in the field of Orthopedics to describe a specific angle in the shoulder joint. It is a measure of the orientation of the glenoid cavity, which is the part of the scapula that forms the socket of the shoulder joint. The glenopolar angle is used to assess the severity of glenoid dysplasia, a condition characterized by abnormal development of the glenoid cavity.
Etymology[edit | edit source]
The term "glenopolar angle" is derived from the words "glenoid", which refers to the socket of the shoulder joint, and "polar", which refers to the direction in which something is measured. The term was first used in medical literature in the late 20th century.
Measurement[edit | edit source]
The glenopolar angle is measured using radiographic imaging. It is defined as the angle between the line from the center of the glenoid cavity to the inferior pole of the scapula and the line perpendicular to the plane of the scapula. A normal glenopolar angle is typically between 30 and 50 degrees. An angle less than 20 degrees is considered indicative of severe glenoid dysplasia.
Clinical significance[edit | edit source]
The glenopolar angle is used in the diagnosis and treatment planning of various shoulder conditions. It is particularly useful in assessing the severity of glenoid dysplasia, a condition that can lead to shoulder instability and osteoarthritis. The angle can also provide information about the orientation of the glenoid cavity, which can be useful in planning surgical procedures such as shoulder arthroplasty.
