GLENOID RESURFACING SYSTEM AND METHOD
20230139576 · 2023-05-04 ·

The present disclosure relates to a system and method for repairing an articular surface. A guide pin may be secured to an articular surface of a glenoid, wherein the guide pin defines a working axis and the working axis is positioned at an angle α relative to the articular surface, wherein angle α is less than or equal to 90 degrees. An excision device may be advanced over the guide pin, wherein the excision device includes a cannulated shaft and at least one cutter, wherein the at least one cutter is generally aligned in a single plane. A generally hemi-spherical excision site may be formed with the excision device within the articular surface of the glenoid.

Interbody spacer and bone plate assembly

Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

Glenoid implant

A glenoid implant is provided and may include a body portion and a stem portion. The stem portion may extend from the body portion along a longitudinal axis. The body portion may include an articular side and a bone-engaging side opposite the articular side. At least a portion of the bone-engaging side may be disposed at a non-parallel angle relative to at least a peripheral edge of the articulation side.

STABILIZED DRILL GUIDE
20170348112 · 2017-12-07 ·

A drill guide includes a working portion and a shaft, with a joint formed between the working portion and the shaft so that the shaft is movable relative to the working portion about the joint. The working portion includes at least one drill guide hole which receives a drill for making a hole in a bone. The joint isolates the working portion from unintentional movements of the shaft so that the working portion remains stable against a bone surface. The joint also enables the shaft to be used as a retractor or pry bar against surrounding anatomical structures if desired. The drill guide may be included in a system with an implant component and/or other surgical instruments.

Glenoid component for use in shoulder arthroplasty

An method includes creating a first bore and a second bore in a glenoid region of a scapula offset from each other by a first distance. A glenoid component is provided that includes a base component having a bearing surface and a first peg and a second peg each extending from a scapula-facing side of the base component and being positioned in non-parallel orientation with respect to each other. At least one of the first peg and the second peg is flexed so that a first end portion of the first peg and a second end portion of the second peg are offset by a second distance which corresponds to the first distance. The first end portion of the first peg and the second end portion of the second peg are then advanced into the first bore and the second bore, respectively.

MATERIALS IN ORTHOPEDICS AND FRACTURE FIXATION
20170340448 · 2017-11-30 ·

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

Arthroscopic tissue scaffold delivery device

A small diameter delivery device capable of delivering a tissue loaded scaffold arthroscopically to a tissue defect or injury site without reducing the pressure at the injury site is provided. The scaffold delivery device of the present invention comprises a plunger system that includes two main components: an insertion tube and an insertion rod. The insertion tube has a flared proximal end for holding a tissue scaffold prior to delivery. An elongate, hollow body extends from the flared proximal end to a distal end of the insertion tube, and defines a passageway that extends through the body for delivery of the tissue scaffold. The insertion rod has an elongate body that extends into a handle at a proximal end and a tip at a distal end. The insertion rod is configured to be removably disposed within the insertion tube for sliding along the passageway to effect delivery of the tissue scaffold through the insertion tube.

PROSTHETIC IMPLANTS INCLUDING A FRAME FOR FIXATION TO BONE AND RELATED METHODS
20220362025 · 2022-11-17 ·

The present disclosure provides for prosthetic implants to be used in various surgical repairs, including for procedures like total shoulder arthroplasties and reverse total shoulder arthroplasties. The implants include two main parts—a frame and a prosthetic component. The frame includes an aperture that is configured to receive the prosthetic component, allowing the prosthetic component to make direct contact with bone at the surgical site. Various configurations are provided that allow the prosthetic component to be coupled to or otherwise engage with the frame, and at least some of the configurations are such that the reverse procedures can be done without having to fully re-tool and/or modify the bone. A variety of procedures resulting from the improved implants are also provided.

ROBOTIC SYSTEM FOR SHOULDER ARTHROPLASTY USING STEMLESS IMPLANT COMPONENTS

Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.

TOTAL WRIST PROSTHESIS AND RELATED METHODS
20170296350 · 2017-10-19 ·

Disclosed is a wrist prosthesis, and methods for implanting same, the prosthesis comprising an elongated radial component having two opposite sides, the first side comprising a stem and the second side comprising a concave dish; an elongated carpal component having two opposite sides, the first side comprising a stem, and the second side comprising a ball end; a lunate component having two opposite sides, the first side comprising a cavity adapted to receive said carpal component's ball end, and the second side comprising a convex surface adapted to engage said radial component's concave dish; wherein said lunate component freely rotates and swivels with respect to both of said carpal and radial components; wherein said stem of said carpal component is adapted for rigid engagement with one or more carpal and/or metatarsal bones; and wherein said stem of said radial component is adapted for rigid engagement with a radius bone.
