A system and method for installation of a k-wire through a scaphoid or other fractured bone can include a guide block for accurate trajectory of a k-wire. A support frame for a guide block can be casted and/or secured into place, and a CT scan is obtained, so the fractured bone and the location of the window can be known in the same three-dimensional space. An ideal k-wire trajectory can be plotted through the fractured bone, and a guide block with a lumen can be designed and printed using a three-dimensional printer. The guide block can be inserted into the frame so the lumen aligns with the ideal k-wire trajectory, and a k-wire can be inserted through the lumen into the fractured bone. The net effect would be ideal placement of the k-wire that would facilitate the ultimate insertion of a percutaneous screw to provide fixation of the fractured bone.
