Self-retaining nail to insertion handle interface

An implant insertion assembly, comprising:

• an insertion handle extending from a proximal end to a distal end, the distal end including an outer wall having a radially recessed surface that defines a first shape about a perimeter thereof, the outer wall including an engagement element;
• and
• an implant extending from a respective distal end to a respective proximal end, the proximal end of the implant including an end wall having an inner surface defining an opening, the opening of the end wall configured to receive the recessed portion of the insertion handle therein, the inner surface defining a second shape configured to extend about the first shape and define a mechanical interlock with the first shape of the outer wall of the recessed surface when the recessed surface is inserted in the opening, wherein the mechanical interlock of the first and second shapes cause torque transmission from the insertion handle to the implant, the proximal end of the implant including a receiving element in the end wall, the receiving element being separate from the mechanical interlock and positioned and oriented to receive the engagement element to removably axially lock the insertion handle to the implant.
