A technique for removal of broken-off needles embedded in the sole of the foot is described. Posteroanterior and lateral x-ray films with a radiopaque marker at the needle entry point make it possible to calculate the position of the needle. Using the marker as a third point of reference, solid geometry is used to identify the position and angle of the needle in the space of the foot. A stab wound using a No. 11 blade is aimed on a 90 degree angle at the middle of the needle, permitting its easy removal.
