Orthopedic screw extension

An orthopedic screw assembly comprising:

• an orthopedic screw arrangement that includes a threaded portion for implantation into a bone and a head portion that includes two side slots in the head portion that form two upwardly extending flanges;
• an orthopedic rod;
• and
• an orthopedic screw extension that is configured to connect to said orthopedic screw arrangement and said orthopedic rod;
• said orthopedic screw extension comprising a body that has a top portion and a bottom portion;
• said top portion includes a top cavity;
• said bottom portion includes a bottom cavity;
• said top portion includes first and second top side openings that are configured to receive a portion of the orthopedic rod;
• said first and second top side openings form first and second upwardly extending arms;
• said top cavity includes a top securing surface that is configured to receive a rod connector to entrap the orthopedic rod in said first and second top side openings;
• said bottom cavity has first and second bottom side openings configured to receive a portion of a top portion of said orthopedic screw arrangement;
• said first and second bottom side openings form first and second downwardly extending arms;
• said first and second downwardly extending arms spaced from one another;
• at least a portion of said bottom cavity is located between said first and second downwardly extending arms;
• a) an inner surface of said first and second downwardly extending arms of said bottom portion of said orthopedic screw extension each include an inwardly extending flange;
• said inwardly extending flange on each of said first and second downwardly extending arms are spaced from one another;
• said inwardly extending flange on each of said first and second downwardly extending arms are spaced from a side edge of said respective first and second downwardly extending arms;
• said bottom cavity is located between said extending flange on each of said first and second downwardly extending arms;
• each of said inwardly extending flanges is configured to engage a side surface of a slot in a head portion of said orthopedic screw arrangement and at least partially extend into the slot in the head portion when said orthopedic screw extension is connected to said orthopedic screw arrangement;
• said bottom cavity extends fully through said bottom portion of said body of said orthopedic screw extension;
• said body includes a connecting member that is located between top and bottom ends of said body;
• said connecting member is movable relative to said body;
• said connecting member is configured to connect to the top portion of said orthopedic screw arrangement to thereby secure said orthopedic screw extension to the top portion of said orthopedic screw arrangement;
• and
• a rod connector that is configured to connect to said top portion of said body and to entrap said orthopedic rod in said first and second top side openings.
