Custom, 3-Dimensional Patient-Specific Instrumentation in Anatomic Total Shoulder Arthroplasty: Part 1-Preoperative Assessment, Preoperative Planning, and Guide Design.

Successful total shoulder arthroplasty relies on a multitude of factors specific to patients, implant selection, and surgical technique. Among technical factors, correct intraoperative placement of prosthetic components is paramount. Three-dimensional computed tomography has emerged as a vital tool, allowing surgeons to measure glenoid inclination, glenoid version, and humeral head subluxation more accurately and reproducibly.

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

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.

Custom, 3-Dimensional Patient-Specific Instrumentation in Anatomic Total Shoulder Arthroplasty: Part 2, Dissection and Soft Tissue Management.

During anatomic total shoulder arthroplasty, careful dissection and meticulous soft tissue management ensure adequate visualization of the articular and bony surfaces, allowing the proper use of surgical instrumentation and ensuring accurate placement of prosthetic components. Exposure must be balanced with protection of the surrounding soft tissues, as well as neurovascular structures, which can have long-term postoperative implications. In Part 2 of this technique series for the management of glenohumeral osteoarthritis, we describe our technical approach for dissection, exposure, and management of soft tissues in anatomic total shoulder arthroplasty, including pearls and pitfalls, as well as a discussion of the benefits and risks of the most common approaches.

Minimal inter-surgeon agreement on the diagnosis of pseudoparalysis in patients with massive rotator cuff tears.

Background: Pseudoparalysis is commonly used to describe patients with severe loss of active elevation associated with advanced rotator cuff disease, but its definition in the literature has been variable. This study aimed to determine how 15 expert shoulder surgeons use the term "pseudoparalysis" when presented with clinical cases and assess clinical agreement on the diagnosis of pseudoparalysis.

Methods: Fifteen expert shoulder surgeons were surveyed regarding 18 patients with magnetic resonance imaging-diagnosed massive rotator cuff tears, restricted active range of motion (ROM), full passive ROM, and without advanced rotator cuff arthropathy (Hamada grade <3).

Revision Lateral Femoral Condyle Osteochondral Allograft Transplantation With the Snowman Technique After Failed Previous Oblong Osteochondral Allograft.

Osteochondral allograft transplantation provides components of both cartilage and subchondral bone and can be used in large and multifocal defects where autologous procedures are limited by donor-site morbidity. Osteochondral allograft transplantation is particularly appealing in the management of failed cartilage repair, as larger defects and subchondral bone involvement are often present, and the use of multiple overlapping plugs might be considered. The described technique provides our preoperative workup and reproducible surgical approach for patients who have undergone previous osteochondral transplantation with graft failure and are young, active patients who would not be otherwise suited for a knee arthroplasty procedure.

Is the radial groove a myth? Is the radial nerve in direct contact with the posterior humerus?

Background: The radial groove is known as a sulcus on the posterior humerus and protects the radial nerve from adjacent muscle and soft tissue. In the literature, there exists heterogeneity regarding the presence of an actual radial groove and the radial nerve's interaction with the periosteum of the humerus. This study aimed to determine if there is a real radial groove, "sulcus," and define the relationship between the radial nerve and the periosteum of the posterior humerus.
