Radiologist-Integrated Finite Element Framework for Acromial Stress in Reverse Shoulder Arthroplasty

Starting soon

Conditions studied: Rotator Cuff Injuries, Shoulder Fractures

In brief

The current prospective single-center study is designed to examine an approach that utilizes both high-resolution CT and MRI scans, coupled with customized finite element modelling to analyze the stress placed on the acromion of patients who have undergone RSA surgery. The degree of rotator cuff deficiency will be assessed using Goutallier classification and quantified as Cuff Deficiency Index (CDI), which directly provides biomechanical information for calculating deltoid forces used in finite element analysis. Von Mises stresses will then be analyzed in anatomically defined acromial zones (Levy zones I-III).
