1. A bladed implant assembly for supporting a prosthesis, the assembly comprising:
a. a monocoque implant having a proximal end and a distal end comprising:
i. a threaded body portion located at a distal end of the monocoque implant;ii. an abutment portion located distally to the body portion;iii. a non-threaded portion located proximally to the threaded body portion;iv. a conical, or frusto-conical proximal end, located proximally to the non-threaded portion; andv. a central bore extending through the monocoque implant body having a distal end and a concave proximal end, having an engagement portion and comprising two or more axially elongated openings radially disposed and extending through the non-threaded portion with one or more L-shaped resilient blades having an elongated distal member and a transverse proximal tab, the elongated distal member extending from the distal end of the axially elongated openings, each elongated distal member of each blade being a portion of the external surface of the non-threaded body portion and configured to move between a retracted position, whereby each of the L-shaped resilient blades radially extends into the central bore and an extended position, whereby each of the L-shaped resilient blades is flush with the external surface of the non-threaded body portion; and b. a shaft member comprising:
i. a distal portion; andii. a detachable actuating proximal portion, wherein the actuating proximal portion includes a distal end having a flat surface and a proximal end having arcuate surface, corresponding to the concave surface of the proximal end of the central bore, said shaft member configured to engage the central bore thereby causing the actuating lower portion to radially extend one or more of each of the L-shaped resilient blades from the non-threaded body portion, anchoring the monocoque implant into bone structure surrounding the monocoque implant located proximally to the abutment portion. |
