[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 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 does a volar displacement mean?
Volar (anterior) displacement of the distal fragment is usually the result of a fall on a flexed wrist. These injuries can occur in conjunction with more proximal forearm fractures, such as Monteggia fracture-dislocations, supracondylar humeral fractures and hand fractures.
What is volar angulation fracture?
Fractures with apex-volar angulation are a result of axial load in supination; there- fore, the palm should be rotated volarly (pronation). Fractures with apex dorsal angulation are a result of pronation force; therefore, the palm should be rotated dorsally (supination).
Does angulated mean displaced?
Angulated– A displaced fracture where the ends of the bone fragments are at an angle to each other. Overriding– A displaced fracture where the bone fragments overlap. Impacted– A complete, displaced fracture where one fragment is driven into (“impacting”) a second piece as a result of trauma.

What is volar tilt of distal radius?
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.
What is volar displacement of the wrist?
In this injury, there is displacement of the bone such that the wrist joint rests in front of its normal anatomic position. The injury is most commonly found after falling on to the back of the hand, or by falling with the hand planted on the ground with your body twisting around the hand.
What is the volar of the wrist?
Volar: Pertaining to the palm or the sole. For example, the volar surface of the forearm is the portion of the forearm that is on the same side as the palm of the hand.
What is a displaced distal radius fracture?
Many distal radius fractures are dorsally displaced due to the nature of the injury (a fall on an outstretched hand). They can be extra-articular—meaning the joint is not involved—or intra-articular, meaning the fractures spread into the wrist joint.
What does dorsally displaced mean?
Dorsal displacement of the soft palate (DDSP) describes the condition where the soft palate displaces upwards to sit on top of the epiglottis (Figure 2). When this happens the soft palate ends up obstructing the opening to the trachea (larynx), and thereby reduces the amount of air that a horse can take in.
What is the difference between angulation and displacement?
Loss of alignment – ‘displacement’ The term ‘displacement’ is often used as a specific term to describe loss of bone alignment along its long axis. Loss of alignment, or displacement, is usually accompanied by some degree of angulation, rotation or change in bone length.
