Abstract
Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position.

1-15. (canceled)
A method, comprising:
- inserting a dovetail extension of a coronal sizing and drill guide into a cavity of a dovetail joint of an adjustment block that is coupled to a tibia;
- securing the dovetail extension within the cavity;
- and
- using fluoroscopy to check a size of a radiopaque element of the coronal sizing and drill guide relative to at least the tibia,
- wherein the radiopaque element has a size and shape that corresponds to a profile of a prosthesis component of a first type having a first size when viewed in an anterior-posterior direction.
21-65. (canceled)
A surgical guide, comprising:
- a body configured to be inserted into an adjustment block that is configured to be coupled to a bone, the body defining at least a first guide hole and a second guide hole, wherein the first and second guide holes are sized and configured to receive a first surgical tool for forming pilot holes in the bone;
- and
- a sizing pattern coupled to the body, the sizing pattern having a size and being coupled to the body at a location for estimating resectioning cuts to be made to the bone.
A coronal guide system, comprising:
- a drill guide comprising a drill guide body configured to be inserted into an adjustment block that is configured to be coupled to a bone, the drill guide body defining at least a first guide hole and a second guide hole, wherein the first and second guide holes are sized and configured to receive a first surgical tool for forming pilot holes in the bone for one or more resectioning cuts;
- and
- a cutting guide comprising a cutting guide body configured to be inserted into the adjustment block, the cutting guide body defining a plurality of slots configured to receive a second surgical tool for forming the one or more resectioning cuts, wherein the first guide hole and the second guide hole of the drill guide correspond to edges of the slot defined by cutting guide.
The coronal guide system 83, wherein the patient-specific adapter further comprises a body having a pin holder extension and a pin coupled to the pin holder, wherein the pin extends parallel to a mechanical axis of the bone.
