  2. Distal radius fracture - Wikipedia

    en.wikipedia.org/wiki/Distal_radius_fracture

    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 ...

  3. Classification of distal radius fractures - Wikipedia

    en.wikipedia.org/wiki/Classification_of_distal...

    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]

  4. Strike and dip - Wikipedia

    en.wikipedia.org/wiki/Strike_and_dip

    In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle ) measured downward from horizontal. [ 1 ]

  5. Spherical coordinate system - Wikipedia

    en.wikipedia.org/wiki/Spherical_coordinate_system

    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.)

  6. Scrub radius - Wikipedia

    en.wikipedia.org/wiki/Scrub_radius

    Zero scrub radius (top) positive scrub radius (center) negative scrub radius (bottom) In an automobile's suspension system, the scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road.

  7. Caster angle - Wikipedia

    en.wikipedia.org/wiki/Caster_angle

    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 ...

  8. Track geometry - Wikipedia

    en.wikipedia.org/wiki/Track_geometry

    The measurement of uniformity is done using a predefined length of string line (normally the same length used in horizontal alignment) along the track. If the midpoint of the measurement has higher elevation, it is called hump deviation. On the other hand, if the midpoint has lower elevation, it is called dip deviation. [9]

  9. Colles' fracture - Wikipedia

    en.wikipedia.org/wiki/Colles'_fracture

    2.5 cm (0.98 inches) proximal to the radio-carpal joint; dorsal displacement and dorsal angulation, together with radial tilt [9] Other characteristics: [10] [7] Radial shortening; Loss of ulnar inclination≤; Radial angulation of the wrist; Comminution at the fracture site; Associated fracture of the ulnar styloid process in more than 60% of ...
