ABSTRACT:
A pin site shield is described for covering the entry or exit site of a surgical pin such as a halo pin, external fixation pin, traction pin, or surgical wire. The pin site shield comprises a collar having a slot for receipt of the surgical pin, a surgical sponge attached to the collar, and means for securing the pin in the slot. The surgical sponge includes a foam pad and a tricot material attached to the foam pad on the side remote from the collar. The surgical sponge has a slit in substantial registration with the slot in the collar, allowing the surgical pin to pass inwardly and outwardly within the slot. Preferably, the collar includes a tapped hole passing through a top side of the slot, and a screw inserted into the tapped hole secures the pin in the slot. The collar also preferably includes a nib on the bottom side of the slot for further assistance in securing the pin in the slot. Typically the tapped hole will form an acute angle with the slot for entrapment of a range of sizes of surgical pins, from traction pins to surgical wires, in the corner of the slot.
