An Uncommon Fracture: A Case Report of a Scapular Fracture in a Young Patient.

Cureus

December 2024

Medical Research, Universidad Francisco Marroquín, Guatemala, GTM.

Scapular fractures are rare, typically resulting from high-energy trauma. These injuries frequently present alongside other thoracic or shoulder injuries. Patients often exhibit posterior shoulder pain, swelling, and limited range of motion, which can suggest a variety of shoulder pathologies.

The effects of the two popular strategies, scapular adduction and depression and scapular posterior tilt, on muscle activity of the trapezius and serratus anterior muscles have not been compared. This study demonstrates the effects of additional scapular adduction and depression or scapular posterior tilt movements on the activation of trapezius and serratus anterior muscles and scapular kinematics during arm raising. Eighteen asymptomatic men performed arm raising tasks with and without additional scapular movements, including scapular adduction and depression or scapular posterior tilt.

Background: Reversed shoulder arthroplasty (rTSA) is often used to restore functionality in patients with joint arthropathy and dysfunctional rotator cuff. As rTSA changes the biomechanical properties of the shoulder, an altered movement pattern of arm and scapula is to be expected. Previous studies focused on changes of the scapulohumeral rhythm during functional elevation tasks.

Outcomes of Augmented versus Standard Baseplates in Reverse Shoulder Arthroplasty.

J Shoulder Elbow Surg

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.

Background: The purpose of this study was to assess impingement-free internal rotation (IR) in a virtual reverse shoulder arthroplasty simulation using a Statistical Shape Model based on scapula size.

Methods: A database of over 10,000 scapulae utilized for preoperative planning for shoulder arthroplasty was analyzed with a Statistical Shape Model to obtain 5 scapula sizes including the mean and 2 standard deviations. For each scapula model, one glenosphere size (33-42 mm) was selected as the best fit based on consensus among 3 shoulder surgeons.
