systems and methods provide for the fixation of osteoporotic and non - osteoporotic long bones , especially colles &# 39 ; fractures . a cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture . the cannula is further adapted to receive an expandable structure , the expandable structure being inserted through the cannula until it is in registration with the circumferential opening . the expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture . the expansion of the expandable structure through the circumferential opening toward the fracture causes compression of cancellous bone and moves fractured cortical bone , thus creating a cavity proximal to the fracture . the cavity is then filled with a flowable bone filling material and the material allowed to harden .
