A glenoid prosthesis includes a head portion and an anchor. The head portion includes a first surface adapted to contact a glenoid and an opposed second surface that is at least partially concave. The anchor extends from the first surface of the head portion and terminates at a distal end. At least one first circular member is disposed between the head portion and the distal end of the anchor and encircle the anchor. At least one second circular member is disposed between the head portion and the distal end of the anchor and encircles the anchor. The at least one first circular member is adapted to engage cortical bone of a glenoid and the at least one second circular member is adapted to engage cancellous bone of a glenoid when the glenoid prosthesis is implanted.

Glenoid implant anchor post

A glenoid component for coupling to a scapula of a subject includes a body. The body includes an articulation surface adapted to articulate with a humeral component, and the body further includes a distal surface adapted to face the glenoid of the scapula. The distal surface includes a base surface portion adapted to face a first portion of the glenoid. The distal surface further includes an augmented surface portion adapted to face a second portion of the glenoid. The base surface portion and the augmented surface portion define an obtuse angle therebetween.

Augmented glenoid components and devices for implanting the same

Provided is a slot anchor guide that includes a medial portion and a lateral portion, the medial portion includes a medial projection configured to span a slot of a fixation plate, where the slot anchor guide is configured to guide an anchor through a predetermined position of a slot of the fixation plate and to mate with the fixation plate to allow a surgeon to place the fixation plate on a bone face by manipulating the lateral portion. Also provided is a tuberosity fracture plate that includes a tuberosity end having a first portion configured to overlay a first tuberosity and a second portion opposite the first portion, a distal portion coupled with and extending away from the tuberosity portion.

Humeral fixation plates

A method of fixating a prosthesis to a glenoid is disclosed. The method includes forming a bore in the glenoid; positioning the prosthesis adjacent the glenoid, where the prosthesis includes a head portion and an anchor extending from a rear surface of the head portion; wherein the anchor includes a first fin and a second fin proximal of the first fin; advancing the anchor into the bore until the first fin is implanted within cancellous bone; and further advancing the anchor in the bore until a proximal-facing surface of the second fin is implanted within cancellous bone and abuts cortical bone.

Prosthesis anchor

An anchor trajectory guide and methods of use thereof are provided. The guide includes a body that has a medial side. The medial side can be placed over a lateral side of a fixation plate. The anchor trajectory guide also includes a locator and a plurality of guide apertures. The locator is disposed on or through the medial side of the body. The locator can be mated with the fixation plate. The guide apertures are disposed through the body at positions corresponding to define anchor locations and orientations to provide good purchase adjacent to or in cortical bone around a medial side of a humerus.

Humeral fixation plate guides

A surgical tool, enabling extraction of a prosthesis from a bony implantation site of that prosthesis, defines a proximo-distal axis and includes a distal end head adapted both to cut at least partially the bonding interface between the prosthesis and the bony material of the implantation site and to fix itself to the prosthesis by rotation centered on the proximo-distal axis, according to embodiments of the present invention.

Osteotome extractor

A prosthesis that mechanically couples with both cancellous bone and cortical bone of a glenoid includes a head portion comprising a rear surface and an articular surface, an anchor member, and a plurality of deformable fins extending radially outward from the anchor member. The anchor member includes a distal end and a proximal end connected to the rear surface of the head portion. The plurality of deformable fins extend radially outward from the anchor member and includes at least a first proximal fin adjacent to the rear surface of the head portion positioned to engage with the cortical bone. The anchor member may also include at least one distal fin located proximate the distal end of the anchor member positioned to engage with the cancellous bone.

An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.
