Title: MEDICAL INSTRUMENT SET FOR TREATING BONY ABERRATIONS OF THE CALCANEUS
Abstract:
A medical instrument set (10, 20, 30, 40, 50) for surgically treating bony aberrations of the calcaneus such as calcaneal compression fractures. The present medical instrument set allows surgical treatment of bony aberrations through a minimally invasive procedure that provides better outcomes than both a closed reduction and an open reduction procedure. The medical instrument set includes one or more of an access needle (40), drill (30), depth guide (20), cement plunger (50), and curette (10). The access needle (40) is used to provide access to a desired calcaneal site and is characterized by a cannula (44) and a removable trocar tip (67). The drill (30) is used to bore into the calcaneus. The depth guide (20) is used to visually indicate how far a medical instrument extends beyond and/or through the access needle cannula (44). The cement plunger (50) is used to introduce bone cement into the desired calcaneal site. The curette (10) is used to mechanically create a void at the desired calcaneal site.
