Abstract
The disclosure includes devices for assisting in performing an ankle arthroplasty on a non-resected bone surface of a tibia and/or a talus. The devices may include patient-specific mating surfaces configured to engage the non-resected bone surface in a single relative position relative to the non-resected bone surface. The patient specific nature of the mating surface portion may be generated in the devices prior to the devices being brought into contact with the bone. The devices may include various cutting guides and holes for receiving fasteners to fasten the devices to the bone. The devices may include various features to enhance the stability and/or surface area contact between the devices and the bones.
