Abstract
A drill-guide device is for use in establishing alignments for bone screws driven into the neck of a femur, for bone immobilization following a femoral-neck fracture, particularly in the circumstance of an intramedullary nail already installed in the shaft of the same femur. The device provides a drill template with at least one pair of horizontally spaced guide bores, which are sufficiently spaced to straddle opposite sides of the intramedullary nail and which can be oriented to produce drilled holes which pass up the femoral neck and into the head of a the femur. The axes of the guide bores converge to a point of their geometric intersection beyond the femoral head. Provision is made for detachably connecting the template to the proximal end of the intramedullary nail and for releasably fixing the vertical position and the elevationally tilted position of the template, for a range of adjustments to adapt the device to the differing sizes and proportions of individual patients.
