Instruments, guides, systems and related methods for total ankle prostheses are disclosed. The instruments, guides, systems and related methods facilitate preparation of a tibia and/or talus of a patient for implantation of a total ankle prosthesis therein. The instruments, guides, systems and related methods also facilitate selection of a particular size of a tibial component, a talus component and/or a tibial insert of the total ankle prosthesis that suits the patient. The instruments, guides, systems and related methods include a tibial trial component, a talar trial component and tibial insert trial component that replicate one or more aspects of the tibial component, the talus component and the tibial insert, respectively, of the total ankle prosthesis. The talar trial component includes an articulation surface that articulates with the tibial insert trial component, and slots that facilitate chamfered resection of the patient's talus for the implantation of the talus component thereon.

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

A fixation device is disclosed including an elongate body extending from a distal end to a proximal end. The distal end defines a blind hole having a diameter and extending to a depth from a distal tip. The diameter of the blind hole is sufficient to receive a k-wire therein.

A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.

Guides, implants, devices, instruments, systems, and assemblies for achieving bone fusion are disclosed. A bone fusion system, including an implant template, a guide wire for insertion through the implant template, a bone plate for receiving the guide wire, and an alignment guide apparatus for coupling to the bone plate. Methods of using a bone fusion system for achieving bone fusion are also disclosed.

Methods for temporarily fixing an orientation of a bone or bones. Methods of correcting a bunion deformity. Bone positioning devices. Methods of using a bone positioning device. Bone preparation guides. Methods of using a bone preparation guide.

A surgical alignment system is provided that 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.

In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

A guided punch is disclosed. The guided punch generally comprises a strike cap comprising a strike surface, a punch comprising a distal cutting edge, and a guide rod. The strike cap defines a first cavity therein. The punch defines a second cavity therein in communication with the first cavity. The guide rod is located within the first and second cavities and extends a predetermined distance beyond the distal cutting edge of the punch. The strike cap and the punch are moveable relative to the guide rod.
