An implant for orthopedic surgery includes an impaling member (101,102), which is separable into portions (102a, 102b) for impaling and attaching to tissue, for example, bone. Once the portions (102a, 102b) of the impaling member (101,102) are separated and attached to the requisite tissue, they may accommodate stabilizing members for fixation, or other instrumentation for procedures such as fusion.
