An example method includes registering a virtual model of a portion of a bone of a patient with a corresponding observed portion of the bone, the virtual model including a representation of a wall of the bone; registering a virtual model of an implant component with a corresponding observed implant component; and indicating, based on the registered virtual model of the portion of the bone and the registered virtual model of the implant component, a position of at least a portion of the implant component relative to a position of the wall of the bone.

An example system for designing a patient matched implant for an orthopedic joint repair surgical procedure includes a memory configured to store a model of a bone of a patient; and processing circuitry. The processing circuitry may be configured to: obtain the model of the bone of the patient; obtain a template model of an implant; determine a shape of a surface of the implant; determine a volume between the shape of the surface of the implant and a surface of the bone defined by the model of the bone; generate, based on the determined volume and the template model, a patient matched implant model; and output a file representing the patient matched implant model.

A reaming instrument includes a reamer head having a cutting face rotatable about a cutting face axis and a drive shaft operably connected to the cutting face at a point spaced radially outwardly from the cutting face axis.

Disclosed is a positioning instrument that includes: two branches equipped at the proximal end thereof with an opposite jaw between which the graft is positioned, the two branches moving closer to one another by a translation movement; and a drill bush including a first hole and a second hole, separated by a distance and sized for the passage and guidance of a bone drill bit. Also disclosed are an instrument kit as well as a method for attaching a graft.

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patients glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.

The present invention provides a jig for shoulder replacement surgery. In particular the present invention provides a pre-assembled jig that facilitates and guides the placement of glenoid component of the implant in shoulder replacement surgery. The present jig (P) is pre-assembled to ensure precision alignment, placing and sizing of the glenoid component of the implant for shoulder replacement surgery based on the difference of cuts in millimeters instead of the usual version measurements in degrees. The present invention (P) guides the glenoid component of shoulder replacement in the precise position and thereby provides accuracy in placement of the component.

A patient specific shoulder guide is provided that includes a hub and a plurality of peripheral members. Each of the peripheral members has a peripheral member height dimension between the patient specific contact surface and a side of the peripheral member opposite the patient specific contact surface. At least one of the peripheral members is a low profile peripheral member in which the peripheral height dimension is less than the peripheral height dimension of at least one other of the peripheral members or is less than the hub height.

A microfracture device for creating small holes in a bone. The microfracture device includes a handle having a body extending along a central longitudinal axis with a proximal end and a distal end; a shaft connected to the distal end of the body, the shaft having a distal tip; wherein the distal tip extends at first angle relative to the central longitudinal axis; a sliding mechanism slidably engaged with a surface of the body and moveable between a first configuration and a second configuration; and wherein the sliding mechanism further comprises a striking surface extending therefrom, wherein the striking surface is positioned at a second angle to the central longitudinal axis that is at least substantially similar to the first angle.
