  • Publication number: 20260114880
    Abstract: Alignment instruments may include joint-line referencing systems having an alignment arm having a body with first and second portions defining first and second sides. The first portion has at least one first pin tube through-hole extending from the first to the second side. The second portion has a first opening on the first side. A pin tube guide member is receivable in the first through-hole. The pin tube guide member has a passageway therethrough. An angelwing alignment member includes a portion receivable in the first opening of the alignment arm. An alignment foot is secured to the second portion, and the alignment foot has a handle and a shim. The shim is positionable in a joint between a first bone and a second bone, the alignment arm is alignable relative to a first bone, and the pin tube guide is operable for securing a pin into the first bone.

  • Patent number: 12427030
    Abstract: Instruments, guides, systems and related methods for total ankle prostheses are disclosed. The instruments, guides, systems and related methods facilitate preparation of a tibia and/or talus of a patient for implantation of a total ankle prosthesis therein. The instruments, guides, systems and related methods also facilitate selection of a particular size of a tibial component, a talus component and/or a tibial insert of the total ankle prosthesis that suits the patient. The instruments, guides, systems and related methods include a tibial trial component, a talar trial component and tibial insert trial component that replicate one or more aspects of the tibial component, the talus component and the tibial insert, respectively, of the total ankle prosthesis. The talar trial component includes an articulation surface that articulates with the tibial insert trial component, and slots that facilitate chamfered resection of the patient's talus for the implantation of the talus component thereon.

  • Publication number: 20250120730
    Abstract: An orthopedic implant that includes a body. The body has a top surface opposite a bottom surface, a front surface opposite a rear surface, and a pair of lateral sides on opposing sides of the body from one another. At least a portion of the bottom surface of the body of the implant includes a concave geometry extending from one lateral side to the other lateral side, with the concave geometry biased such that the concave geometry is either closer to the front surface or the rear surface of the body of the implant. Also disclosed is an instrument configured to be coupled with an orthopedic trial. The instrument includes an engagement portion that attaches to other instruments that are configured to facilitate manipulation of the instrument. The engagement portion includes one or more apertures configured to receive at least a portion of one or more protrusions of an instrument.
