An improved fixation assembly for orthopedic applications. The fixation assembly includes a screw having an upper shank portion, a middle section with a recessed area, and a lower threaded section. A locking ring surrounds the recessed area of the screw, with the diameter of the locking ring being greater than the diameter of the recessed area of said screw and less than the diameter of the shank and threaded sections of the screw. The screw and locking ring combination is used to attach an orthopedic plate to a bone. The orthopedic plate includes a hole for receiving the screw and the locking ring. The hole includes an upper section and a lower section, wherein the width of the upper section is less than the width of the locking ring so that the locking ring is compressed while in the upper section of the hole. The width of the lower section is greater than the width of the locking ring so that the locking ring is not compressed while in the lower section of the hole.
A fixation assembly for fixating an orthopedic plate to a bone, said fixation assembly comprising:
A method of fixating an orthopedic plate to a bone, said orthopedic plate including a hole for receiving a screw and a locking ring, the hole including an upper section and a lower section, wherein the width of the upper section is less than the width of the locking ring so that the locking ring is compressed while in the upper section of the hole, and wherein the width of the lower section is greater than the width of the locking ring so that the locking ring is not compressed while in the lower section of the hole, said method comprising the steps of:
