December 30, 2008 Gymnastic complaints extend beyond common growth plate injuries By Christiana Schmitz Adolescent gymnasts are developing a wider variety of arm, wrist, and hand injuries than previously described in gymnast-related medical literature. Of the 125 patients evaluated in a study presented at the 2008 RSNA meeting, researchers isolated the MRIs of 12 gymnasts aged 12 to 16. The images revealed a pattern of injury that spanned far beyond the growth plate injuries commonly associated…
