"Don't jump on the bed".

Jumping on the bed is a common childhood behavior. However, little is known about the potential for traumatic injury sustainable as a consequence of this behavior save for an understanding of the risk of injury related to falling from a bed, and a growing body of literature related to trampoline injuries. We report a case of a "grid" wire puncture injury that required a minor incision to affect removal. Parents should know about the possibility of this injury secondary to jumping on the bed, and pediatricians should know that the grid wires have hooked ends that may require incision to facilitate their removal.
