Custom, 3-Dimensional Patient-Specific Instrumentation in Anatomic Total Shoulder Arthroplasty: Part 3-Prosthesis Placement, Subscapularis Repair, and Postoperative Rehabilitation.

ABSTRACT

The proposed benefits of stemless humeral implants include greater bone preservation, decreased cortical stress shielding, less risk of diaphyseal stress risers, decreased surgical time, and greater ease of implant removal during revision surgery. In part 3 of this comprehensive technique series on the management of glenohumeral arthritis, we present our step-by-step surgical technique for use of a patient-specific 3-dimensionally printed glenoid drill guide, placement of a stemless anatomic total shoulder prosthesis, and subscapularis repair, and we highlight our protocol for postoperative rehabilitation.
