Abstract
A combined inserter for insertion of an intramedullary nail and a bone plate together. The combined inserter includes a body that includes a longitudinal axis, a distal end, and a proximal end. The combined inserter includes an intramedullary nail coupler coupled to the body and configured to couple to an intramedullary nail; and a bone plate coupler coupled to the body and configured to couple to a bone plate.
Claims26
A system that enables insertion of an intramedullary nail and a bone plate, the system comprising:
- an intramedullary nail configured to span a fracture in a bone;
- a bone plate configured to span the fracture;
- and
- a combined inserter comprising:
- a body comprising a longitudinal axis, a distal end, and a proximal end;
- an intramedullary nail coupler coupled to the body and configured to couple to an intramedullary nail;
- and
- a bone plate coupler coupled to the body and configured to couple to the bone plate;
- wherein:
- the bone plate coupler is configured to be adjustable along a transverse axis that is transverse to the longitudinal axis;
- the bone plate is configured to contact an epiphysis and a diaphysis of the bone;
- the combined inserter is configured to insert the intramedullary nail into a distal femur;
- and
- the combined inserter is configured to enable simultaneous attachment to the intramedullary nail and the bone plate.

A femur fixation system, comprising:
- an intramedullary nail comprising a set of nail fastener openings configured to accept a fastener, the intramedullary nail configured to slide into an intramedullary canal of a distal end of a femur of a patient;
- a bone plate comprising a set of plate fastener openings;
- a combined inserter configured to enable simultaneous attachment to the intramedullary nail and the bone plate, the combined inserter comprising:
- a body comprising a longitudinal axis, a distal end, and a proximal end;
- an intramedullary nail coupler coupled to the body and configured to couple to the intramedullary nail;
- a bone plate coupler coupled to the body and configured to couple to the bone plate;
- and
- a set of nail engagement openings that align with at least one of the set of nail fastener openings, the set of nail engagement openings disposed in the body;
- a set of nail engagement fasteners configured to engage both the bone plate and the intramedullary nail when deployed;
- and
- a set of nail avoidance fasteners configured to engage the bone plate and the femur of the patient when deployed;
- wherein:
- the bone plate is configured to contact an epiphysis and a diaphysis of the femur;
- a first plate fastener opening of the set of plate fastener openings is configured to be positioned on a first side of a fracture of the femur;
- and
- a second plate fastener opening of the set of plate fastener openings is configured to be positioned on a second side of the fracture.
