Abstract

An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.
