A Novel Surgical Technique for Removing Buried Cannulated Screws Using a Guidewire and Countersink: A Report of Two Cases.

Chen Y, Giri KP, Pearce CJ - Open Orthop J (2015)

Bottom Line: The problem is further compounded when the initial screw was inserted percutaneously or via a minimally-invasive (MIS) technique.This technique is especially useful in removing cannulated screws which have been inserted using small stab incisions and MIS techniques initially.This technique can be applied to the removal of buried cannulated screws which are placed into any bone in the body.

ABSTRACT
Removal of metal implants is a common procedure that is performed for a variety of indications. However, problems such as a buried screw head may occasionally arise and render hardware removal difficult or even impossible. The problem is further compounded when the initial screw was inserted percutaneously or via a minimally-invasive (MIS) technique. In the present paper, we introduce a novel, minimally invasive technique to remove buried cannulated screws which obviates the need for excessive extension of the skin incision, surgical exploration, soft tissue dissection or excess bone removal, which surgeons may otherwise have to undertake to uncover the buried screw head. This technique is especially useful in removing cannulated screws which have been inserted using small stab incisions and MIS techniques initially. This technique can be applied to the removal of buried cannulated screws which are placed into any bone in the body.

Mentions: The tip of the cannulated guidewire is then placed in the centre of the circle and the wire is aligned along the direction of the x-ray beam. The cannulated guidewire is then driven into the cannulated hole of the screw under fluoroscopic guidance (Fig. 2). A cannulated countersink is subsequently passed through the guidewire and used to remove the excess bony and soft tissue overgrowth, until the buried screw head is fully uncovered, ensuring that corresponding cannulated screw driver can be properly seated onto the screw head (Fig. 3). The uncovered screw can now be removed in the usual manner.
