Prosthetic implant, and a method and tool for the insertion of same

A prosthetic implant, comprising:

• an anterior end;
• a posterior end located opposite of the anterior end;
• and
• left and right side portions separating the anterior end from the posterior end, each of the left and right side portions having top end serrations and substantially opposing bottom end serrations, the serrations comprising a plurality of peaks, wherein at least one pair of adjacent peaks are separated by a lower radius.

A method of placing a prosthetic implant, the method comprising:

• providing a prosthetic implant, the implant comprising:
• an anterior end including an anterior tooling aperture and anterior rotational tooling apertures;
• a posterior end being located opposite of the anterior end, the anterior end being larger than the posterior end, and wherein the posterior end includes a posterior tooling aperture and posterior rotational tooling apertures;
• a left side portion and an opposite right side portion separating the anterior end from the posterior end;
• and
• a top side and an opposite bottom side on each of the left side portion and the right side portion, the top and bottom sides of each left side portion and right side portion having serrations;
• creating a void in either the anterior or the posterior side of a vertebrae in a spinal column;
• and
• inserting the posterior end of the prosthetic implant into the vertebrae first if the void is created from the anterior side of the vertebrae, or inserting the anterior end of the prosthetic implant into the vertebrae first if the void is created from the posterior side of the vertebrae.

A prosthetic implant tool assembly, the tool assembly comprising:

• an inner shaft having a threaded end portion configured to engage a portion of a prosthetic implant;
• an inner shaft handle positioned substantially opposite the threaded end portion;
• an outer shaft substantially coaxial to the inner shaft and configured to receive the inner shaft, the outer shaft captured between the inner shaft handle and the prosthetic implant when the threaded portion of the inner shaft is engaged with the portion of the prosthetic implant;
• a plurality of tooling pins positioned substantially at an end of the outer shaft;
• a handle positioned along the outer shaft substantially opposite the plurality of tooling pins, and configured to receive a rotational force and couple the rotational force, via the outer shaft, to the plurality of tooling pins.
