Loss of radial inclination is associated with loss of grip strength. [5] Radial length - It is the vertical distance in millimetres between a line tangential to the articular surface of the ulna and a tangential line drawn at the most distal point of radius (radial styloid). Shortening of radial length more than 4mm is associated with wrist ...
The radius or radial distance is the Euclidean distance from the origin O to P. The inclination (or polar angle) is the signed angle from the zenith reference direction to the line segment OP. (Elevation may be used as the polar angle instead of inclination; see below.)
Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]
The radial inclination of a distal radius fracture is shown in red in image at right. The angle is measured between: [4] [5] A line drawn between the distal ends of the articular surface of the radius on an AP view of the wrist. A line that is perpendicular to the diaphysis of the radius. Radial inclination is normally 21-25°. [6]
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle The caster angle [ 1 ] or castor angle [ 2 ] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car , motorcycle ...

Exostosis of inferior humerus and/or glenoid measuring 3–7 mm, and slight irregularity of the joint Severe: Exostosis of inferior humerus and/or glenoid measuring more than 7 mm in height as well as sclerosis and narrowing of the joint space (normal joint space is 4–5 mm). [5]
