Shoulder instability can occur in any direction and presents across a broad spectrum including traumatic dislocations, repetitive microinstability events or subluxations, and global joint laxity. The development of pain, functional decline, and articular pathologic condition is a multifaceted process that is influenced by the underlying bony morphology, biology of the surrounding soft tissue structures, dynamic coordination of the periscapular musculature, and patient factors such as age, activity level, and associated injuries. This article will focus on the younger, active patient with instability due to deficiencies in the capsulolabral complex and dynamic stabilizers.

Purpose: This study aims to compare the biomechanical performance of elastic and static suture-based cerclage systems to traditional screw constructs in the setting of modeled glenoid bony augmentation.
Methods: Biomechanical testing was conducted on polyurethane cellular foam blocks modeling a 20 % glenoid defect repaired with a coracoid graft. Constructs consisted of an elastic suture-based cerclage, static suture-based cerclage, and a two-screw construct.

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.

The pursuit of aesthetically pleasing shoulder contours, particularly those characterised by a sharp, angular definition, has gained significant traction in Southeast Asia. Traditionally, neuromodulators have been used to achieve these results by inducing muscle atrophy, particularly in the trapezius muscles. However, this approach can carry potential risks, such as compromised muscle function and spinal instability.

Background: Resilience refers to the ability to adapt or recover from stress. There is increasing appreciation that it plays an important role in wholistic patient-centered care and may affect patient outcomes, including those of orthopaedic surgery. Despite being a focus of the current orthopaedic evidence, there is no strong understanding yet of whether resilience is a stable patient quality or a dynamic one that may be modified perioperatively to improve patient-reported outcome scores.

Background: Superior labrum anterior-posterior (SLAP) lesions are common shoulder injuries. The 10-type classification system has been widely used to diagnose SLAP lesions since it was proposed. However, growing evidence from arthroscopic studies indicates the existence of many SLAP lesions, especially those associated with superior glenoid humeral ligament (SGHL) injuries, that were not included in the initial classification.
