Post-traumatic ulna plus variance associated with poor outcomes for distal radius fractures
Researchers in this study found that post-traumatic ulna plus
variance greater than 2 mm was the only factor significantly associated
with poor outcome when analyzing a cohort of young patients with
unilateral distal radius fractures who were not yet at risk for
osteoporosis.
“The present study showed that post-traumatic ulna [plus variance] is
the most important factor in predicting bad outcome in non-osteoporotic
patients, but that especially intra-articular fractures and to a lesser
extent dorsal tilt may be of importance too,” the researchers wrote in
the study abstract.
The researchers evaluated pre-reduction anteroposterior and lateral
wrist radiographs from 66 patients with a median age of 42 years,
according to the abstract. They measured fracture pattern, radial
length, inclination, joint surface tilt, ulnar variance and measured
outcomes using the Gartland and Werley score.
Although not statistically significant, the researchers noted that
intra-articular fracture pattern may also be a strong marker for a poor
outcome.
