US 12,575,840 B2 · Ankle joint system and related methods

Abstract

Systems and related methods for preparing and treating damage in an ankle joint. The system may include one or more of a reamer, a surgical device, a tibial implant, a placement tool, and a talar implant. The reamer may prepare an intramedullary canal for implantation of an implant. The reamer may include a plurality of nested reamer elements that may be expanded into the intramedullary canal. The surgical device may include a housing containing the reamer and be configured to orient the reamer with the intramedullary canal. The tibial implant may include a plurality of stem components. The placement tool may be configured to combine the plurality of stem components. The talar implant may be configured to be implanted in a talus.

Dependent claims

A surgical device comprising:

a housing comprising:
a longitudinal length disposed along a first axis;
a width, and
at least one location feature disposed on the longitudinal length;
a reamer nested entirely within the housing and comprising a plurality of nested reamer elements comprising a first reamer element and a second reamer element nested within the first reamer element, the first reamer element and the second reamer element configured to telescope out of the housing;
and
an adjustment mechanism comprising:
a first adjustment mechanism face disposed on a second axis and configured to contact an anterior surface of a patient's tibia;
and
wherein the adjustment mechanism is configured to be movably attached to the housing along the longitudinal length.

7 more elements

A method of orienting a reamer comprising:

providing the reamer comprising a plurality of nested reamer elements;
orienting the reamer within a housing, the housing comprising at least one location feature;
providing an adjustment mechanism comprising a first adjustment mechanism face configured to contact an anterior surface of a patient's tibia;
movably affixing the adjustment mechanism to the housing;
positioning the housing partially within a resected area of a patient's tibia joint based on a position of the at least one location feature of the housing with respect to the anterior surface of the patient's tibia;
sliding the adjustment mechanism along a longitudinal length of the housing until the first adjustment mechanism face contacts the anterior surface of the patient's tibia;
and
determining whether the adjustment mechanism, when contacting the anterior surface of the patient's tibia, aligns the reamer with an intramedullary canal of the patient's tibia.
