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.

Abstract: Systems for modular bone fixation may include first, second, and at least one third portion to aid in fracture reduction, simplify the surgical procedure, increase fracture fixation strength, and reduce irritation to the patient caused by the implant. In some examples, the at least one third portion may be separable from the first and second portions to further simplify the surgical procedure and reduce irritation to the patient.

Abstract: An implantable medical device may include an implant member having an aperture extending therethrough. An anchor member may be configured to extend through the aperture. A locking ring may be supplied to inhibit back-out of the anchor member.

Abstract: A composite interbody spacer includes a first portion formed of a first material and a second portion formed of a second material.

Abstract: A faceplate for at least partially covering a plurality of anchor member apertures in an implantable member includes a main body sized to at least partially overlap the plurality of anchor member apertures of the implantable member and configured to inhibit anchor member back-out from the plurality of anchor member apertures. A locking tab may be associated with the main body, the locking tab being formed to at least partially elastically deform to engage the implantable member and secure the main body in place.
