Abstract
A bone screw cutting system can include a cutting assembly having a plurality of blades. The system can further include a position adjustment assembly coupled to the cutting assembly and configured to receive a bone screw blank and position the bone screw blank relative to the cutting assembly. The cutting assembly is configured to cut a bone screw blank received by the position adjustment assembly and to form a self-tapping end portion at a cut end of a resulting cut bone screw.
Claims17
An orthopedic implant kit, comprising:
- a base;
- a plurality of bone screws received on the base, wherein the plurality of bone screws comprises a plurality of cortical locking bone screws which each have threads in a head of the cortical locking bone screw, and a plurality of cortical bone screws which each are without threads in a head of the cortical bone screw, wherein one or more of the plurality of bone screws and the base are sterilized, wherein the plurality of cortical locking bone screws consists of exactly four cortical locking bone screws, and wherein the plurality of cortical bone screws consists of exactly two cortical bone screws;
- and
- a tibial plateau leveling osteotomy (TPLO) plate secured on the base, the TPLO plate comprising an elongated body comprising a first portion and a second portion, wherein the elongated body of the TPLO plate is curved in an X-Y plane such that the first portion is offset from the second portion in a direction along the X-axis, wherein a straight line that extends in a direction of a length dimension of the second portion extends in a direction of the Y-axis, wherein the length dimension of the second portion is longer than that of the first portion, wherein the second portion comprises two or more screw holes spaced apart along the second portion, wherein the first portion comprises a plurality of screw holes arranged in a triangular pattern, and wherein each of the plurality of screw holes of the first portion is offset from the straight line along the X-axis in the same direction such that all of the screw holes of the first portion are on the same side of the straight line as one another.
