ABSTRACT:
A blind-hole locating system wherein a drill jig, which is to be removably attached to the proximal end of a given intramedullary nail, incorporates outrigger structure for support and orientation of one or more drill guides, such that positioning and alignment with one or more bone-screw holes of the nail can be checked and ascertained as a preliminary step, and such that a precise spacer or stabilizer carried by this jig can be known to contact the nail, on an alignment transverse to the nail and to a geometric plane which includes the nail axis and the axis of at least one of the bone-screw holes of the nail, such stabilizer contact being achieved only for the case of correct drill-guide alignment with one or more bone-screw holes. Having thus ascertained that the spacer correctly identifies drill-guide alignment with bone-screw holes, it is only necessary, after installing the nail and connecting the jig to the proximal end of the nail, to make a small local surgical incision through flesh and bone sufficient to enable direct stabilizer contact with the nail, whereupon it is known that the drill guides are in correctly drillable alignment with the targeted bone-screw holes of the installed nail. Drilling and setting of bone screws can immediately proceed in customary manner.
