1. A method of treating a spinal irregularity by attaining stability between spinal segments, said method comprising:
providing an orthopedic fixation device, wherein the orthopedic fixation device includes:
a coupling element, wherein the coupling element comprises a bore extending therethrough and an interior surface disposed about the bore;
a bone fastener, wherein the bone fastener comprises a head and an extension that extends from the head, wherein the head is configured for loading into the coupling element through the bottom of the bore, wherein an outer surface of the head is roughened;
a locking clamp assembly, wherein the locking clamp assembly includes:
a clamp element having a spherical outer surface, a spherical inner surface, a rim extending around the spherical outer surface and disposed between an upper end and a lower end of the clamp element, and a plurality of slits extending through the clamp element and the rim, wherein at least a portion of the outer surface is configured to engage the interior surface of the coupling element, and wherein at least a portion of the inner surface is configured to engage the head of the bone fastener, wherein the spherical inner surface is roughened to engage with the outer surface of the head; and
a wedge element, wherein the wedge element comprises a wedge bore configured to receive an upper portion of the clamp element and an inner wedge surface disposed around at least a lower portion of the wedge bore, wherein the inner wedge surface is configured to engage at least a portion of the outer surface of the clamp element,
implanting the bone fastener into a vertebrae;
positioning the coupling element to the bone fastener;
angulating the bone fastener relative to the coupling element; and
locking a position of the coupling element relative to the bone fastener.
