Orthopedic compression implants and systems and methods of installing the same
Systems and methods for tibial plateau leveling osteotomy (TPLO) are disclosed. In some embodiments, a method comprises: resecting a tibial plateau to form a resected portion; arranging the resected portion in an altered position with respect to a tibial shaft; preparing a plurality of openings, the plurality of openings comprising a first opening and a third opening formed in the tibial shaft, a second opening formed in the resected portion; and advancing a staple-style orthopedic implant into the plurality of openings, the staple-style orthopedic implant comprising: a bridge having curved contour between a first end and a second end; and a plurality of legs extending from the bridge, the plurality of legs comprising: a first leg extending from the first end; a second leg extending from the second end; and a third leg, wherein each leg of the plurality of legs corresponds with each opening of the plurality of openings.
1 . A method for performing tibial plateau leveling osteotomy, the method comprising:
resecting a tibial plateau to form a resected bone portion and an unaltered bone portion;
arranging the resected bone portion in an altered position with respect to the unaltered bone portion and a tibial shaft;
preparing at least three openings in the resected bone portion and the unaltered bone portion, wherein the at least three openings are formed in-line across the resected bone portion and the unaltered bone portion, and wherein two of the at least three openings are formed in the unaltered bone portion;
advancing a first staple-style orthopedic implant of at least two staple-style orthopedic implants into the at least three openings, the first staple-style orthopedic implant comprising:
a bridge extending between a first end and a second end; and
at least three legs extending from the bridge, wherein each leg of the at least three legs:
corresponds with an opening of the at least three openings; and
comprises one or more teeth for preventing pulling out of the corresponding opening; and
advancing a second staple-style orthopedic implant of the at least two staple-style orthopedic implants into the resected bone portion and the unaltered bone portion,
wherein a combination of the first staple-style orthopedic implant and the second staple-style orthopedic implant provides stability by reducing rotation and migration of the resected bone portion and the unaltered bone portion relative to the unaltered bone portion.
2 . The method of claim 1 , wherein the at least three legs are configured such that a first leg extends from the first end, a second leg extends from the second end, and a third leg extends from a position on the bridge between the first end and the second end.
3 . The method of claim 2 , wherein a third opening of the at least three openings is formed in the resected bone portion.
4 . The method of claim 3 , wherein the first leg extends into the first opening, the second leg extends into the second opening, and the third leg extends into the third opening.
5 . The method of claim 4 , wherein the step of preparing at least three openings comprises embedding a surface of the resected bone portion and a surface of the unaltered bone portion using a surgical tool.
6 . The method of claim 5 , wherein the second staple-style orthopedic implant comprises a bridge extending between a first end and a second end, and at least three legs extending from the bridge.
7 . The method of claim 5 , wherein the step of advancing a second staple-style orthopedic implant involves advancing two legs of the at least three legs of the second staple-style orthopedic implant into the unaltered bone portion.
