Abstract: Multi-function targeting guides for minimally invasive 1st metatarso-phalangeal (MTP) joint fusion or arthrodesis configured to be positioned with a superficial anatomy-based surface match to establish precise positioning for surgical cuts, drilling, burring, and orthopedic screw affixation. Surgical apparatuses, namely bone reamers, reamer guides, burr sleeves, and positioners to assist in the joint fusion procedure. Methods of using the multi-functional targeting guides and surgical apparatus in conducting a MTP arthrodesis procedure.

Abstract: Surgical methods for multi-component ankle prosthesis are provided that include use of 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. Methods including a sagittal sizing guide body include positioning a first radiopaque object at a first position and a second radiopaque object located at a second position that is spaced apart from the first position.

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.
