The need  to explant screws and plates placed at other institutions using different fixation systems is not an uncommon situation in the life of a surgeon. However, having the right instrumentation in place is not always a matter of course. The new screw removal set was designed to meet these requirement. It is a compact set of screw driver blades that can be used  for removal of 0.9mm and 3.2mm screws with various drive configurations, commonly  used in CMF procedures.

The New Screw Removal Set includes blades for the most common available drive mechanisms including :

• Cruciform                
• Torx
• Hex                        
• Center (Square)
• Clutch drive (Slotted)
• Slotted
• Phillips                    
• THORP

An osteotome is included in the set to remove boney in growth around the screw head . It is designed with a hex-coupling allowing it to be used with either a screw driver handle or with a trauma drill.

In addition, the set also contains a broken screw extractor for screw shafts of 1.0 mm to 3.2 mm in diameter with a sheared off head. In smaller diameters the extractor device cores out the bone surrounding the  shaft of the screw and removes it without making contact .The  internal threads will then engage the screw threads and remove it without further trephining of the  bone along the screw length.

For removal of screws with damaged or stripped head a  conical threaded device (quick coupling) or stripped screw extractors (hex coupling) is inserted vertically along the long axis of screw until it engages the core of the screw. The reverse threading of the instrument will then draw the screw (counterclockwise) out of the bony  fragment.

Locking pliers available to help grab and remove screw parts close to the bone surface. As new drives are introduced to the CMF market, additional blades will be made available to complete the universal screw removal set.
