Patent number: 12121233Abstract: Systems and methods for tibial plateau leveling osteotomy (TPLO) are disclosed. According to some embodiments, an osteotomy method may include cutting a tibia with an arcuate cut to separate a tibial plateau of the tibia from a tibial base of the tibia, rotating the tibial plateau relative to the tibial base from a first orientation to a second orientation, and, with the tibial plateau in the second orientation relative to the tibial base, securing an implant to the tibia to secure the tibial plateau to the tibial base. Securing the implant to the tibia may include embedding a first leg of the implant into the tibial base, and embedding a second leg of the implant into the tibial plateau such that the first and second legs apply compression urging the tibial plateau toward the tibial base.Type: GrantFiled: February 3, 2023Date of Patent: October 22, 2024Inventors: Robert Glen Coleman, Michael Sherman, Dimitri Protopsaltis
