A device for external orthopedic fixations, which has one or more frames which have a substantially and/or partially annular shape and are suitable for being arranged around a limb to surround it at least partially, wherein one or more rods are fixed to a frame by means of a locking mechanism is provided. The device has two jaws which, when closed, tighten the locking mechanism to a portion of the frame by exerting a prevalently axial force, wherein the jaws are closed by means of a cam mechanism suitable for being actuated by rotating a lever pivoted to a first jaw and provided with one or more cam surfaces cooperating with a surface of the second jaw.

Device for external orthopedic fixations

Surgical prosthetic modular devices used singularly or stacked together are provided for use to replace excised vertebral tissue. The devices are rigid plugs, dimensionally similar to normal vertebral bodies, and have ridged faces to engage adjacent vertebral bodies or to interdigitate when stacked. Ridges extend in both the medial/lateral and anterior/posterior directions to prevent slipping in the anterior/posterior and medial/lateral directions respectively. A locking screw may be used to secure a stack to form a singular rigid prosthetic device. The devices are also provided with a plurality of threaded openings. In the method of this invention, a device is used to replace excised vertebral tissue, threaded bolts are inserted into the threaded openings, and other spine stabilization devices are attached to the bolts. In corporectomies, the device can be bolted to a plate, which in turn is fixed to adjacent vertebrae. In spondylectomies, the device can be fixed to a series of posteriorly placed rods.
