Glenohumeral joint arthrosis development is to be fully understood, mainly due to arthrosis origin not being fully understood. Only some factors such as age, gender or past joint fractures have been associated with its development. Although joint complexity and the challenges of an in-vivo study, computer-based analysis has proven to be useful and a viable tool to understand joint failure and fatigue. Taking this into account, a finite element model of the glenohumeral joint could allow professionals to understand how rotator cuff injury induces glenohumeral arthrosis development. Furthermore, if the finite element model is fine-tuned based on in-situ measurements, such as Glenhohumeral muscles forces and force changes due to injury. The finite element model would be more robust, reliable and credibleFirstly, based on a CT scan a 3D segmentation of the glenohumeral joint was created (including humerus, clavicle and scapula). Afterwards, rotator cuff muscles (Supraspinatus, Infraspinatus, teres minor and subscapularis) were segmented with the coracohumeral and glenohumeral ligaments. This final model could then be fine-tuned based on the inter-articular forces measured by a new novel in-situ FSR based circuit in cadaveric pieces. Doing so, this validated model could help identify what muscle or group of muscles contributes more to the development of glenohumeral joint arthrosis.
