The boxers splint provides superior immobilization for 4th and 5th metacarpal neck fractures (boxers fractures). A volar cut out allows the MCP to be flexed to 90 degrees facilitating a reduction maneuver and providing appropriate MCP flexion for extended immobilization. Adult size is 4"X12" with a 3" elastic bandage, child size is 3"X10" with a 2" elastic bandage. Both kits come with or without water for fiberglass activation. Adult size is recommended for subjects greater than 5'4" tall, child less than 5'4" tall. Please review the application video for best results.
