Mixed-reality surgical system with physical markers for registration of virtual models
An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
Total ankle replacement trial and preparation systems
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.
Anatomical Wedge Implant
An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.
ORTHOPEDIC FASTENERS, INSTRUMENTS, AND METHODS
A solution is disclosed for deploying a fixation member into an aperture of a bone fastener. The solution may include a guide having a body that includes a proximal end and a distal end. The guide may also include a guide member coupled to the body near the proximal end. The guide member may be configured to guide placement of the fixation member to secure the bone fastener. The solution may include an engagement member coupled to the body near the distal end. The engagement member can be configured to engage the bone fastener such that the guide member is rotatable, relative to the bone fastener, about an engagement axis to the guide member at any of the plurality of relative orientations about the engagement axis.
Ankle replacement system and method
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.
Anatomical wedge implant
An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.
TOTAL ANKLE REPLACEMENT INSTRUMENTS, ASSEMBLY, AND METHODS OF USE
The present disclosure relates to an instrument. The instrument includes a handle coupled with a rod, and a body portion configured to receive the rod in a central portion thereof. The instrument also includes a coupling portion configured to releasably couple with one or more components of an implant. Actuation of the handle drives the rod to actuate a first implant component relative to a second implant component so as to position the first implant component adjacent the second implant component.
Fixation apparatus and method for total ankle replacement
A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.
TALAR IMPLANT
Provided is a prosthesis for ankle arthroplasty including a talar dome component configured to be attached to a talus bone. Also provided is a guide instrument for guiding a reamer to prepare a talus to receive the talar dome component.
Circular fixator system and method
A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.
