ABSTRACT:
A new method for locking Intramedullary Nails (IM Nails) using a headless screw for performing interlocking with the nail. A subsequent, canulated outer screw is placed in such a way that it encapsulates this headless screw. The outer screw locks to the IM Nail and holds the headless screw in place to eliminate play in the screw-nail interface and results in a more stable form of fixation.
