Abstract
|
|
|
In the literature, it is extremely difficult and takes long time to remove middle part of segmentally broken screws using ball-tip guide and extraction hook after femoral interlocking intramedullary nailing. Proximal part of broken locked screw can be removed with screwdriver easily, but it is very difficult to remove distal and especially middle part of broken screw which are usually angulated and should be removed to avoid interference with further procedure and complications.
So we designed a technique for removal of segmentally broken distal locked screw which can be removed after withdrawal of nail proximally to realign screw segments and then actually applied this method to real case with short operative time and satisfactory outcome.
