GLENOID IMPLANT SURGERY USING PATIENT SPECIFIC INSTRUMENTATION

A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement.

Humeral implant anchor system

A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.

PATIENT-SPECIFIC GUIDES FOR LATARJET PROCEDURE
20230063081 · 2023-03-02 ·

Patient-specific guides for the Latarjet procedure, as well as surgical systems and methods of performing the Latarjet procedure to treat glenohumeral instability using such patient-specific guides are disclosed. A patient-specific coracoid guide and a patient-specific glenoid guide may be configured based on preoperatively generated three-dimensional models of the patient's shoulder anatomy. Guides may be configured for coracoid graft preparation and glenoid decortication. The coracoid graft may be placed in the desired position based on three-dimensional (3D) preoperative planning.

Captured Slotted Reamer
20230112855 · 2023-04-13 ·

Described herein are cannulated reamer designs and methods. In one embodiment, a reamer comprises a cannulated central body portion, a plurality of cutting legs and outer frame. The cannulated central body portion has an inner wall surface and an opposing outer wall surface defining a thickness and a bone contacting surface and an opposing distal end surface defining a length, the inner wall surface defining a bore about a central longitudinal axis of the cannulated central body portion. The plurality of cutting legs extends outwardly from the cannulated central body portion. The other defines a periphery of the reamer, the outer frame coupled to a lateral end of each of the plurality of cutting legs. The cannulated central body portion has a recess extending entirely through the thickness and only partially though the length.

ANGLED BASEPLATE FOR HUMERAL AND GLENOID ARTICULAR SURFACE IMPLANT SYSTEMS AND METHODS
20230062240 · 2023-03-02 ·

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

SYSTEM AND METHOD FOR SOFT TISSUE AND BONE REPAIR
20230103416 · 2023-04-06 ·

A soft tissue and bone repair system and corresponding method are provided which are particularly useful for labral repairs in the human shoulder. The system comprises at least two guide cannulae capable of being introduced into an anatomical structure of a human body at different entry points for repair of a tear in soft tissue. A pulling line can be passed within the anatomical structure between the guide cannulae. A guide device may be attached to the pulling line and inserted into one of the guide cannula. The guide device is capable of delivering a drilling device into the anatomical structure. The pulling line is capable of being pulled to move an end of the guide device from a one location to another within the anatomical structure to position the drilling device on a desired drilling path to access the tear in soft tissue.

Arthroscopic tunnel guide for rotator cuff repair

A drill guide assembly for drilling a tunnel having a fixed, non-zero radius of curvature, where the drill guide assembly includes a housing and a sleeve, or cutting tube, configured to reciprocate within the distal portion where the sleeve, or cutting tube, is configured to receive a bone cutting instrument.

OFFSET GUIDE

An offset guide that places a surgical tool through a bone of a surgical joint. The offset guide may hold the surgical joint in a reduced configuration at a first location along the bone; the first location preferred for engaging the bone. The offset guide may engage the bone with a hook that engages two opposing sides of the bone to center the surgical tool through the bone. The offset guide may guide placement of a surgical tool through the bone center at a second location along the bone, the second location offset from the first location. The second location may be a preferable location for receiving the surgical tool therethrough. The surgical tool may include both a drill and an implant insertion tool. The implant insertion tool may place an implant at the second location, while the offset guide holds the surgical joint.

HUMERAL IMPLANT ANCHOR SYSTEM

A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.

Shoulder prosthesis components and assemblies

An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.
