“…These studies, although informative, are limited in scope by various parameters. For example, some studies only include a certain geographic area [ 16 , 19 , 20 , 23 , 24 , 25 ], only those admitted to the hospital [ 14 , 19 , 20 , 24 ], short time periods [ 16 , 17 , 23 , 25 ], or difficult fractures [ 15 , 26 ]. Most are either limited to powder firearms [ 14 , 15 , 16 , 17 , 19 , 20 , 23 , 24 , 25 ] or non-powder firearms [ 18 ] and very few studies mention spine fractures [ 14 , 19 ].…”
