Abstract
Intramedullary aiming systems, instruments, and methods of treating bone fractures are provided. The aiming systems may include one or more instruments configured to ensure optimal alignment and placement of one or more components of an intramedullary nailing system, such as anteversion alignment, anti-rotation, lag screw aiming, distal aiming, and other instruments suitable to enhance and optimize the surgical procedure.
Claims20
A method of inserting an intramedullary nail in a bone of a patient, the method comprising:
- inserting a coring reamer instrument into an axial end of a long bone to access a medullary canal, the coring reamer having a hollow coring tip with circumferential teeth configured to cut and collect bone;
- securing an intramedullary nail to a nail insertion handle with a keyed interface and a connection bolt, the nail insertion handle includes an implant holder including a coupling portion and a handle portion, wherein the coupling portion includes keyed tabs configured to mate with corresponding recesses in the proximal end of the intramedullary nail, and the connection bolt passes through internal threads in the implant holder and threads into the intramedullary nail;
- and
- inserting the intramedullary nail into the medullary canal with the nail insertion handle.
A method of inserting an intramedullary nail in a bone of a patient, the method comprising:
- inserting a coring reamer instrument into an axial end of a long bone to access a medullary canal, the coring reamer having a hollow coring tip with circumferential teeth configured to cut and collect bone;
- providing a targeting system including:
- the intramedullary nail having a proximal end and a distal end;
- a nail insertion handle including a coupling portion to removably couple to the proximal end of the intramedullary nail, a handle portion, and an aiming guide having an opening that aligns with an opening in the intramedullary nail;
- a driver sleeve positionable through the opening in the aiming guide;
- a wire sleeve positionable through the driver sleeve, the wire sleeve having a plurality of graduated markings;
- and
- a guide wire positionable through the wire sleeve, wherein when the wire sleeve is flush with the guide wire, a reading of the driver sleeve next to the graduated markings indicates an optimal lag screw length
- inserting the intramedullary nail into the medullary canal with the nail insertion handle.
