A dual-trajectory pedicle screw system includes an internally threaded sleeve and including first part and cylindrical second part, the first part being recessed to form a space, and the second part including projections on top; a main screw including a universal head and a first conic member, the universal head including first and second threaded holes, the first threaded hole being inclined at a first angle, the second threaded hole being inclined at a different second angle, bottom of the universal head being a convex and rotatably disposed in the space; and an auxiliary screw including external threads threadedly secured to the first or second threaded hole so that the auxiliary screw is secured to the main screw at the first or second angle with respect to the main screw, a second conic member extending downward from the external threads, and a fitting member on top of the external threads.

Dual-trajectory pedicle screw system for improvement of fixation stability

An apparatus, for reinforcing bone and tools for mounting the same, has an implant including a barrel and a device. The implant can be expanded by an expanding apparatus including an outer tube, a base, a hollow body and a handle. The expanding apparatus can be bound to the implant to place the implant into a bone to be treated and adjust the expansion degree. The expanding apparatus can be replaced by an injector apparatus including a container for bone cement and an injecting handle. The injector apparatus can inject a mixture for reinforcing bone (e.g., bone cement) into the bone through an exit, the device, the aperture, the barrel and the window of the barrel, and into the to-be treated area.
