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.

The cannulated screw is located under fluoroscopicguidance and a corresponding skin incision is made. Thefluoroscopy unit is then adjusted until a perfect circle of thecannulated hole of the buried screw is clearly visible on the screen.

Mentions: Under general or regional anaesthesia, the patient is cleaned and draped in the routine fashion on a radiolucent table. The cannulated screw to be removed is located under fluoroscopy and a stab incision made on the overlying skin over the original scar. The fluoroscopy unit is then adjusted until a perfect circle of the cannulated hole of the buried screw is clearly visible on the screen (Fig. 1). This step is familiar to surgeons who have experience in placing distal interlocking screws through cephallomedullary nails for the femur and tibia via percutaneous stab incisions.
