Background: Glenoid loosening is an issue in anatomic total shoulder arthroplasty (a-TSA). This has been attributed to abnormal glenoid anatomy, common among these patients. Different alternatives have been proposed to tackle glenoid bone loss and restore joint alignment with augmented glenoid implants being increasingly used to deal with this problem. This systematic review aims to evaluate the clinical and radiological outcomes of patients undergoing augmented glenoid a-TSAs. Our hypothesis was that augmented glenoid components will lead to good patient outcomes with a low incidence of complications and revision procedures.
Methods: MEDLINE, EMBASE, CENTRAL and CINHAL were searched from inception to February 2022 for information pertaining to outcomes of patients undergoing a-TSA with augmented glenoid implants.
Results: Eighteen studies reported on outcomes of 814 a-TSA (800 participants) with a mean follow-up of 3.7 years. Most studies (67%) were Type IV level of evidence. Almost 70% of participants underwent an a-TSA secondary to primary glenohumeral osteoarthritis. Most glenoids were type B2 (73%). Augmented glenoids material was mostly all-polyethylene (81%) with full wedge (45%) and stepped components (38%) designs being the most common. Most studies reported good clinical outcomes. 17 patients (4%) underwent a revision surgery.
Conclusions: Our review found that patients undergoing a-TSA with augmented glenoid components report good outcomes at short-to-mid-term follow-up. Further research is warranted to determine if such outcomes remain similar in long term.

Minimum two-year follow-up of a reverse total shoulder arthroplasty using a wedged baseplate.

Background: Avoiding inclination of the glenoid baseplate in reverse shoulder arthroplasty often requires considerable glenoid reaming. It is proposed that the use of a metal wedged baseplate in all patients can achieve neutral inclination with reduced glenoid reaming.
Materials And Methods: A prospective clinical single-centre study with minimum two-year follow-up was carried out.

Article Synopsis
- - The study aimed to measure the biomechanical stability of two fixation methods (suture button and suture tape cerclage) for anterior glenoid bone grafts, comparing hand tensioning to device tensioning.
- - Researchers tested artificial bone blocks and recorded how much displacement occurred under various forces while using a cyclic loading protocol.
- - Results showed that device tensioning provided significantly better stability than hand tensioning for both methods, particularly at forces over 100 N, with suture buttons performing better than suture tape at higher loads.
Subscapularis Muscle Radiographic Integrity and Patient-Reported Outcomes Following Arthroscopic Anatomic Glenoid Reconstruction With Distal Tibial Allograft.

Department of Orthopaedic Surgery, Nova Scotia Health, Halifax, Nova Scotia, Canada.
Background: Shoulder stabilization surgery has evolved over time, and bony augmentation procedures on the glenoid side are being performed more often. The Latarjet procedure modifies subscapularis anatomy because the conjoined tendon divides the subscapularis muscle fibers through a split/takedown, which has structural and functional implications. Arthroscopic anatomic glenoid reconstruction (AAGR) re-creates anatomy.

Introduction: Recurrent shoulder dislocations often cause attrition of the labrum and progressive loss of the anterior bony contour of the glenoid. Treatment options for this pathology involve either soft tissue repair or bony augmentation procedure. The optimal management for patients with shoulder instability with subcritical bone loss remains unknown and current clinical practice is highly varied.
