  • Patent number: 6126664
    Abstract: A device and method for the location of a pedicle and resection of the corresponding lamina are disclosed. The device includes an osteotome having a cutting element configured and dimensioned to remove a section of bone sized to accommodate a portion of an implant; and a pedicle finder having a handle at a proximal end for manipulation of the pedicle finder, a pedicle locator at a distal end connected to the handle by a shaft, and a osteotome guide located on the shaft configured and dimensioned to slidingly engage at least a portion of the osteotome. By providing the osteotome guide on the same device as the pedicle locator and configuring the cutting element of the osteotome and osteotome guide to remove a fixed section of bone, the size and position of the resected bone is optimized to help ensure proper seating of an implant such as a pedicle hook.
