What is acceptable angulation?
Table of Contents
Radiographs should be obtained between 1 and 2 weeks after initial reduction to detect early angulation. In fractures in any level in children less than 9 years of age, complete displacement, 15 degrees of angulation, and 45 degrees of malrotation are acceptable.
What is the dorsal angulation distal radius fracture?
In children 9 years of age or older, 30 degrees of malrotation is acceptable, with 10 degrees of angulation for proximal fractures and 15 degrees for more distal fractures.
What is volar angulation?
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 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.
What is a right distal radius fracture?
When the radius breaks near the wrist, it is called a distal radius fracture. The break usually happens due to falling on an outstretched or flexed hand. It can also happen in a car accident, a bike accident, a skiing accident or another sports activity.
What is fracture angulation?
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. varus/valgus. radial/ulnar.
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).
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.
What does minimal angulation mean?
Our definition of minimal angulation was a fracture with angulation of 15° or less in the sagittal plane of the radiograph. 3–5. Minimal displacement was defined as translational displacement of 5 mm or less on the frontal plane.
What type of fracture is a distal radius fracture?
Distal radius fractures are one of the most common types of bone fractures. They occur at the end of the radius bone near the wrist. Depending on the angle of the break, distal radius fractures can be classified into two types: Colles or Smith. Falls are the main cause of distal radius fractures.
