Background: The treatment decisions for shoulder instability often necessitate surgical intervention, with glenoid bone loss being a key factor. Currently, various techniques exist to identify glenoid bone loss, each with its own advantages and disadvantages. This study introduces the Coraco-Gleno-Scapular (CGS) line as a tool for assessing critical glenoid bone defects. The objective is to define the CGS line and evaluate its utility in guiding clinical decisions regarding bone loss, proposing that defects extending posterior to this line indicate critical bone involvement requiring surgical intervention.
Methods: The study analyzed 50 normal right shoulders from individuals aged 18-40 years. Using 3D en face views of the glenoid, the CGS line was defined from the anteroinferior base of the coracoid process, crossing the anterior glenoid, to the anteroinferior pole of the scapula. The best-fit circle area method and the glenoid index linear method were used to calculate the percentage of the bone area located anterior to the CGS line.
Results: The best fit circle area method revealed a mean glenoid surface area anterior to the CGS line of 22.19%, while the glenoid index linear method indicated a mean area of 27.2% anterior to the CGS line. Of the 50 shoulders, 14 had a glenoid surface area <20% anterior to the CGS line using the best-fit circle method, with no cases below 17.5%, while 36 individuals had a glenoid surface area >20%.
Conclusion: The Coraco-Gleno-Scapular line is a reliable and simple tool for assessing glenoid bone loss, providing valuable guidance in managing shoulder instability. Its ease of use makes it a promising candidate for standard application in clinical practice.
Level Of Evidence: Prospective observational study, Level III.

Dynamic anterior stabilization of the shoulder using buttons.

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.

Background: Arthroscopic Bankart repair (ABR) and the open Latarjet (OL) procedure are the most frequently preferred methods in the treatment of anterior glenohumeral instability. The aim of this study was to compare patients who underwent ABR or OL due to anterior glenohumeral instability in terms of functional capacity, glenohumeral bone loss, residual apprehension, redislocation, and dislocation arthropathy.
Methods: A total of 56 patients who underwent ABR or OL due to anterior glenohumeral instability between January 2018 and December 2021 were evaluated retrospectively.

A 25-year-old male presented with a ballistic fracture of the right glenoid resulting in > 30% loss of the posterior glenoid articular surface and acute posterior glenohumeral instability that was treated with open reduction internal fixation with iliac crest autograft transfer. There is limited consensus on the operative management of ballistic intra-articular fractures due to the heterogeneity of these injuries. Acute posterior glenohumeral instability secondary to a ballistic fracture is a rare injury pattern.

Introduction The role of the condylar position in the correct functioning of the stomatognathic system has been the center of the study. Using cone-beam computed tomography (CBCT), this study looked at the three-dimensional (3D) position of the condylar bone in patients from Class I, Class II, Division 1, and Division 2. Materials and methods This cross-sectional, retrospective study was conducted using 102 CBCT records, with 34 records allocated to each category of malocclusion classification, such as dentoskeletal Class I, skeletal Class II, and dental Class II, Division 1 and 2.

Aims: The aim of this study was to report long-term clinical outcomes of a modern convertible metal-backed glenoid (MBG) in total shoulder arthroplasty (TSA).
Methods: After a minimum of 15 years, a previously studied cohort of 35 patients who received a modern convertible MBG during the period 1996 to 2005 was contacted for clinical and radiological follow-up. At last follow-up, patients were evaluated radiologically and clinically according to the Constant Score, Simple Shoulder Test, and visual analogue scale for pain.
