The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A method of forming a shoulder prosthesis includes resecting an end portion of a humerus to form a resected end of the humerus and a resected portion separated from the humerus, the resected portion having an outer convex surface and an inner surface. The inner surface of the resected portion is processed to include a concave articular surface. The outer convex surface of the resected portion is implanted in the resected end of the humerus. An implant having a convex articular surface is secured to a glenoid. The concave articular surface of the resected portion is articulated with the convex articular surface of the implant.

A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.

Described herein are examples of orthopedic reamer heads for preparing a bone to receive an implant, as well as methods of assembling reamer heads. An illustrative example of a modular reamer head can include a body and a cutting system. The body can include a generally dome shape having an outer surface extending from an apex region to a base. The outer surface can have a recess including one or more arcuate channels that extend from the apex region towards the base of the dome. The cutting system can have one or more arcuate elements having cutting elements. One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.

A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail. The self-locking construct includes an adjustable first loop and an adjustable second loop coupled thereto. The method includes implanting an anchor in bone, the anchor slidably mounted to the tail. The tail is positioned relative to the tissue. An end of the tail is inserted through the first loop. The tail is passed through the first loop, the second loop is pulled into the anchor, and the self-locking construct is positioned relative to the tissue. The self-locking construct is tightened against the tissue by pulling on an end of the self-locking construct. The first loop is tightened onto the second loop.

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.

A arthroplasty trial tool for a human shoulder can include a handle, a first sensor, and a user interface. The handle can include a first end and a second end opposite the first end. The first sensor can produce a first sensor signal as a function of a sensed shoulder condition. The user interface can be configured to display a first value as a function of the first sensor signal.

A modular shoulder prosthesis system, in at least one embodiment, provides flexibility in shoulder replacements and ability to switch between a traditional anatomic Total Shoulder Replacement (ta-TSR) to a reverse Total Shoulder Replacement (r-TSR). Optionally, the system provides for a modular adaptation for the glenoid side in a TSR. The system includes a baseplate, a modular component, a humeral base and a modular humeral component. The baseplate includes a base with at least two attachment points extending in from opposed outer circumferential sides of the base. The modular component and the modular humeral component configured to cooperate with each other. The baseplate and the humeral base, or alternatively a second baseplate, are capable of attachment to different modular components to facilitate both ta-TSR and r-TSR with a change in the attached modular component.

This disclosure relates to surgical devices and methods for repairing bone defects. The defect indicators disclosed herein may be utilized to indicate a precise location of the defect associated with an articular surface of a joint.

An instrument assembly for a shoulder arthroplasty that can comprise: a cut guide having a slot for aiding a resection of a head of a humerus; and a positioning assembly configured to position the cut guide relative to the head of the humerus, wherein the positioning assembly is configured to couple to a reamer. The positioning assembly can comprise: a boom configured to position the cut guide relative to the reamer and the head of the humerus along a first axis; and an arm coupled to the cut guide and configured to be moveable to position the cut guide relative to the head of the humerus about the reamer in a second axis.
