Results
A distal radius fracture is a common bone fracture in the forearm.
Every third woman and every 5th man over the age of 50 years have osteoporotic fracture according to the report of the International Osteoporosis Foundation [1].
The most common low-energy fracture is a fracture of the distal forearm (2-3 times more common in women than in men [2]).
The risk of fractures throughout life for women is 16%.
In addition,
the fracture of the distal forearm - the first osteoporotic fracture,
which occurs much earlier than other,
more complex fractures (mortality after hip fracture is 20% ) [3].
A method for assessment of bone mineral density using DR data only was suggested.
Additional X-ray studies are not required.
Three groups of female and male were compared by nonparametric Mann Whitney test (Fig.
3).
Significant differences in the median values of the parameter Es-BMD (Estimated bone mineral density) determined by DR in the group of patients without fracture and fracture with displacement have been demonstrated .
The overall shape of the curves has met with reference curve of CT osteodensitometry (UCSP scale),
Fig.4,5,6.
However,
the decline in the Es-BMD with age is not so sharp.
Values within the range from 1SD to 2SD can be attributed to “osteopenia” (Fig.
5,
c,red area).
If Es-BMD value less 2SD was consider “osteoporosis”, Fig.5,6. These patients are needed to be directed to study of mineral metabolism.
This will prevent the appearance more severe fractures.
Undoubtedly to obtain the most reliable results in bone mineral density based on the DR data,
we need to analyze a significantly larger number of patients.
