Certain Childhood Fractures May Signal Low Bone Density: Study01/10/14
FRIDAY, Jan. 10, 2014 (HealthDay News) -- Certain types of
fractures may indicate lower bone strength in children, a new study
For the study, published online Jan. 7 in the
Journal of Bone and Mineral Research, researchers compared
bone strength in 115 boys and girls, aged 8 to 15, who suffered
forearm fractures and 108 children without fractures.
Using sophisticated CT scans to assess bone quality, the
investigators found that children with a forearm fracture due to
mild trauma (such as a fall from standing height) had weaker bones
than other children. The researchers added that this decreased bone
strength may put these children at increased risk for fractures
from weakened bone later in life.
"Our study highlights the need for clinicians to consider the level of trauma preceding the injury, when treating children and adolescents who present with fracture," lead author Joshua Farr, a research fellow at Mayo Clinic in Rochester, Minn., said in a Mayo news release.
"Fractures from moderate trauma appear more likely to occur in the setting of normal bone strength. But fractures resulting from mild trauma suggest an underlying skeletal deficit," he explained. Moderate trauma would include a fall from a relatively low height, such as from a bicycle.
"We can't say with certainty that these skeletal deficits will track into adulthood. They may be transient," Farr added. "But we think that trauma classification is a clinical variable that could be used to more closely monitor kids who are suffering mild-trauma fractures. Intervention in terms of diet and physical activity might be used to optimize bone strength."
Broken bones are common in children and affect about one in
three healthy youngsters. Forearm fractures are the most common and
occur most often during the growth spurt that children typically
have in early adolescence.
