There is a well-recognized association between osseous defects of the glenoid or humerus and shoulder dislocation, which often leads to recurrent instability. A variety of strategies have been used to treat bone loss, and procedures have become more refined as the goals of surgery have evolved. Achieving optimal motion and function and minimizing the risk of osteoarthritis have become almost as important as stabilizing the joint.

Eccentric Reaming is Superior to Augmented Components in B2 Glenoids: a Biomechanical study.
J Shoulder Elbow Surg
January 2025
Division of Orthopaedic Surgery, The Ottawa Hospital, University of Ottawa, Ottawa, ON, Canada. Electronic address:
Introduction: Primary glenohumeral arthritis is typically associated with glenoid retroversion and posterior bone loss. Glenoid component fixation remains a weak link in the survivorship of anatomical total shoulder arthroplasty, particularly in the B2 glenoid. The aim of this study was to compare biomechanical properties of two glenoid preparation techniques in a B2 glenoid bone loss model.

Arthroscopic Bankart repair (ABR) is associated with an increased failure rate over time. The Recenter implant, a metal block, is designed to reinforce capsulolabral repair. The aim of this study was to evaluate whether the addition of the Recenter implant to ABR reduces the rate of recurrence in patients with glenohumeral anterior instability.

Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.
Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.

Background: Glenoid bone loss presents a complex challenge in the management of patients with glenohumeral osteoarthritis (GHOA) undergoing Reverse Shoulder Arthroplasty (RSA). Eccentric reaming and bone grafting have been utilized to address this issue but are associated with their own set of challenges. This study explores the effectiveness of augmented glenoid baseplate RSA in addressing glenoid bone loss.

JSES Int

NAEON Institute, São Paulo, Brazil.
Background: Surgical procedures to treat anterior shoulder instability are essentially divided into those for significant bone loss and those without relevant bone loss. However, there is a gray area between these procedures that would not require bone grafting but would benefit from improved stabilization mechanisms. This study evaluates a technique based on the triple soft tissue block, the dynamic anterior stabilization of the shoulder, using an adjustable button.
