What is dorsal angulation of a fracture?
Fracture angulation describes a specific type of fracture displacement where the normal axis of the bone has been altered such that the distal portion of the bone points off in a different direction. Angulation is described using words like: dorsal/palmar.
What does volar angulation mean?
[17, 18] A negative volar tilt indicates dorsal angulation of the distal, radial articular surface (see image below). The volar tilt, or palmar/volar inclination, is an angle between a line drawn perpendicular to the long axis of the radius and a tangential line drawn along the radial articular surface.
What is dorsal angulation?
Dorsal angulation of the articular surface of the radius was measured on the lateral view as the angle between a line connecting the dorsal and palmar lips of the radius and a line perpendicular to the central axis of the radius12.
What is the right distal radius?
The distal radius is the end (distal) portion of the forearm bone (radius). It connects to the carpal bones at the wrist and runs parallel to the ulna, which is the other bone of the forearm.
How do you know if you have a broken angulation?
To describe fracture angulation the direction of the distal bone and degree of angulation in relation to the proximal bone should be stated. Medial angulation can be termed ‘varus’, and lateral angulation can be termed ‘valgus’.
What is angulation in orthopedics?
Angulation. Used to describe diaphyseal or metaphyseal fractures, angulation is expressed in degrees and described by the direction of the apex of the angle. Angulation may be present on more than one view. Soft Tissue. Soft tissue injury has a significant effect on the treatment and prognosis of an injury.
What is radial angulation?
Radial inclination or angle. Radial inclination represents the angle between one line connecting the radial styloid tip and the ulnar aspect of the distal radius and a second line perpendicular to the longitudinal axis of the radius. The radial inclination ranges between 21 and 25 degrees .
What is proximal radius fracture?
Proximal radius fractures include fractures of the proximal portion of the radius including the radial neck and head. They are often associated with other injuries including olecranon fractures, elbow dislocations, medial epicondyle fractures and ulna shaft fractures.
What is normal volar tilt?
Volar tilt is a measurement made on the lateral projection of the wrist as an angle of the distal radial surface with respect to a line perpendicular to the shaft. A normal range is considered at around 10-25° 1. An angle >25° can lead to dorsal intercalated segment instability 2.
What is a distal radial metaphyseal fracture?
Distal radial fractures are a heterogeneous group of fractures that occur at the distal radius and are the dominant fracture type at the wrist. These common fractures usually occur when significant force is applied to the distal radial metaphysis.
