Grip Lock Injuries to the Forearm in Male Gymnasts

Abstract

We performed an epidemiologic survey to estimate the number of grip lock injuries occurring among male high school and college gymnasts. These injuries occur when dowel grips used by the gymnast become locked on the bar as the gymnast's momentum carries him through the skill being performed. We also questioned injured gymnasts to obtain details of their injuries. Thir ty-eight high school coaches reported 17 injuries and 32 college coaches reported 21 injuries for a 10-year period; 36% of the coaches responding reported at least one such injury in their program. Of the 23 injured gymnasts who returned detailed questionnaires, 20 had sustained fractures and 9 required surgery. The distal forearm or wrist were the areas injured most often. Fourteen gymnasts had residual pain, seven had functional limitations, and eight had limited motion in the wrist. Fifteen of the 23 athletes were using a cubital (hyperpronated) grip at the time of injury and 19 were using dowel grips. Among the reasons cited for the injury, 18 gymnasts thought that their grips were either too large, worn, or stretched; 8 said the grips slid up their wrists, and 7 cited technical errors.
