Abstract

Background:

Although fractures of the distal radius are a common clinical presentation, many factors affect instability of these injuries. The aim of this study was to assess the influence of age, sex, distal radial ulnar joint injury (DRUJ), ulnar styloid fracture, and dorsal displacement in late collapse of distal radius fractures.

Methods:

Three hundred twenty-nine patient fractures were measured for dorsal tilt, radial inclination and ulnar variance after reduction and 2 months later. Reduction loss was analysed statistically against variables like DRUJ involvement, ulnar styloid fractures, age, sex, and AO classification.

Results:

After two months there was loss of reduction in 171(51.9%) cases. Loss of reduction was related to age, AO classification, involvement of DRUJ, ulnar styloid fractures and initial displacement.

Conclusions:

Factors such as age, associated DRUJ injury, ulnar styloid fracture are predictive of loss of reduction. Knowing these predictor factors, can aid in decision regarding treatment methods.

Key Words:

Distal Radius Fracture, Radial Tilt, Ulnar Variance, Volar Tilt, Ulnar Styloid Fracture, DRUJ.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Stress-Strain Diagram - Brittle Materials

Stress-Strain Diagram - Brittle Materials

Brittle materials, including glass, cast iron, and stone, exhibit unique characteristics. They fracture without considerable change in their elongation rate, indicating that their breaking and ultimate strength are equivalent. Such materials also show lower strain levels at the point of rupture. The failure in brittle materials predominantly results from normal stresses, as evidenced by the rupture created along a surface perpendicular to the applied load. These materials do not display...
