    摘要： Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' 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.

    摘要： A method and apparatus for creating or enlarging a cavity in a patient's body are provided. One implementation of the apparatus includes a head, a pushrod and a handle. The head is rotatable about a first axis and is configured to effectuate a medical procedure. The pushrod is attached at a distal end to the head and attached at a proximal end to a handle. The pushrod is configured to translate along a second axis substantially perpendicular to the first axis, where translation of the pushrod along the second axis rotates the head about the first axis. The handle includes a lever coupled at one first end to the pushrod and pivoting the lever about the third axis translates the pushrod along the second axis.
