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.

CANAL SPARING HUMERAL IMPLANT AND RELATED METHODS
20210393414 · 2021-12-23 ·

A humeral implant is provided. The implant includes a humeral stem including a plurality of fins. At least one fin comprises a serrated bottom edge. A radial distance between an inner bottom edge of the at least one fin and a centerline of the humeral implant increases along a distal length of extension of the at least one fin. At least the serrated bottom edge of the at least one fin is configured to cut into and compact bone of the metaphysis of a humerus toward relatively denser cancellous bone of a peripheral portion of the humerus when press-fit therein, thereby providing sufficient press-fitting for cementless fixation of the humeral stem into the humerus. Related kits and methods are also provided.

Arthroscopic Shoulder Arthroplasty, Components, Instruments, and Method Thereof
20210386561 · 2021-12-16 ·

A novel method and instrumentation for insertion of humeral and glenoid total shoulder implant using arthroscopic visualization for bony preparation as well as insertion of components through small incisions. Mini instruments and cannulated guides and reamers are used in order to perform the procedure under direct arthroscopic visualization. For ease of insertion, the components are inserted separately and assembled in situ. Securing the humeral components in place is accomplished with bicortical screw transfixing the central peg of component. Also disclosed are components, parts thereof and instruments used therewith.

GLENOID REPAIR SYSTEM AND METHODS OF USE THEREOF
20210378686 · 2021-12-09 ·

The present disclosure provides systems and methods for repairing a defect on a portion of an articular surface of a human body, particularly of the glenoid. More particularly, the present disclosure provides systems and methods for repairing both a glenoid cavity and a glenoid rim of the glenoid using a single implant.

Humeral head implant system
11369479 · 2022-06-28 · ·

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.

Open Latarjet for correction of anterior-inferior glenoid bone loss

Embodiments of the present disclosure are directed to instrumentation that facilitate coracoid-glenoid fixation in Latarjet procedures. For example, a single instrument, a coracoid resection tool, may be provided/utilized to prepare a coracoid bone graft for size, flatness, and hole drilling. A glenoid drill guide may further be provided/utilized that uses sized offsets for placement of the coracoid graft flush with the glenoid. Further embodiments of the disclosure are directed to corresponding methods that employ this instrumentation. For example, a surgeon may employs the coracoid resection tool as a guide to plane the inferior coracoid surface that will serve as the coracoid graft surface. The coracoid resection tool may further guide the placement of coracoid holes along the length of the coracoid and orient the holes approximately perpendicular to the planed coracoid graft surface. For example a proximal coracoid hole may be positioned towards the proximal end (i.e., the cut end) of the resected coracoid while a distal coracoid hole may be positioned towards the distal end (i.e., the tip) of the resected coracoid.

GLENOID IMPLANT HAVING MULTIPLE SECTIONS OF DIFFERING DIAMETERS
20220175543 · 2022-06-09 ·

Disclosed are prosthesis systems and methods that provide ways by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

Patient specific reconstructive glenoid systems and methods

A system for repairing a glenoid defect of a specific patient can include a patient-specific punch and a patient-specific shaping block. The patient-specific punch can form a patient-specific glenoid implant from a bone puck. The patient-specific shaping block can shape the patient-specific glenoid implant to match and fill a glenoid defect of a specific patient.

Glenoid fossa prosthesis
11344422 · 2022-05-31 ·

The improved glenoid fossa prosthesis for repair of a scapular deficient patient includes a base with a fixed flange, and a separable flange. A conical taper on the base and a complimentary locator edge positively orient the separable flange when joined with the base for affixation by screw. A plurality of flange fixation screws penetrates the scapular tissue between the flanges for affixation of the flanges thereto. The flange thickness is variable to approximate the topography of the scapular tissue in the affixation area to minimize tissue trimming during fitment. A cutting mask attaches to the deficient scapula in the glenoid fossa area to guide the physician in trimming scapular tissue for fitment. A cortical screw further fixates the base to the scapular tissue. A second conical taper on the base serves as a mount for a glenoid sphere (reverse shoulder) or socket (standard shoulder) repair configuration.

SYSTEMS AND METHODS FOR SHOULDER PROSTHESES

Provided is a method for converting a modular anatomic shoulder implant to a modular reverse shoulder implant, wherein the modular anatomic shoulder implant and the modular reverse shoulder implant have novel configurations.
