Patient-Specific Musculoskeletal Modeling of Total Shoulder Arthroplasty
<p>Total shoulder arthroplasty (TSA) is often considered a surgery of last resort for patients with debilitating pathologies of the glenohumeral joint such as osteoarthritis, humeral head fracture, and advancing rotator cuff tears. TSA replaces the articulation between the humeral head and the …

Finite Element Modeling of Patient-Specific Total Shoulder Arthroplasty
<p>Total Shoulder Arthroplasty (TSA) is a surgical procedure designed to improve joint functionality by replacing the articulation between the humeral head and the glenoid fossa. Anatomic Total Shoulder Arthroplasty (aTSA) and Reverse Total Shoulder Arthroplasty (rTSA) are two types of replacement …

Computational simulation of bone remodelling post reverse total shoulder arthroplasty
… the response of bone following a reverse shoulder procedure. The reverse shoulder procedure investigated here is for rotary cuff deficient patients. In this procedure up to 75 % complications are reported in some clinical series. It is therefore necessary, for the design of successful …

Side-to-Side Comparison of Total Shoulder Arthroplasty and Intact Function in Individuals
<p>Total Shoulder Arthroplasty (TSA) is a surgery which replaces the shoulder joint, or the interface between the humerus and the scapula glenoid. To test TSA success, most prior research compares patients with TSA to healthy controls. However, the shoulder anthropometry, motion, and musculature of …

Design and Development Towards a Novel Prosthesis for Total Shoulder Arthroplasty to Reduce Aseptic Glenoid Loosening
Total shoulder arthroplasty (TSA) is the most common surgical solution, that helps in restoring the structural and functional integrity of a diseased glenohumeral (GH) joint with intact rotator-cuff. A 300% increase in the usage of TSA has been observed since 2007, along with 2.5% increase in …

Multi-objective design optimization of reverse total shoulder arthroplasty to maximize range of motion and joint stability
<p>Reverse total shoulder arthroplasty was developed to restore range of motion (ROM) and joint stability to patients with pre-operative conditions that are not addressed by conventional replacements. Although reverse total shoulder arthroplasty is the current gold standard for treating a range of …

Technique and application of a non-invasive three dimensional image matching method for the study of total shoulder arthroplasty
… of in-vivo glenohumeral joint biomechanics after total shoulder arthroplasty are important for the improvement of patient function, implant longevity and surgical technique. No data has been published on the in-vivo glenohumeral joint contact locations in patients after total shoulder …

Statistical Shape Modeling to Quantify Variation in the Proximal Humeral Anatomy
… humeral head center are important factors in Total Shoulder Arthroplasty (TSA). The objective of this thesis was to develop a Statistical Shape Model (SSM) of the cortical and cancellous bone regions of the proximal humerus, and to assess potential shape differences with gender and ethnicity, …

Biomechanical assessment of RTSA functional outcomes towards optimising the prosthesis configuration
Reverse total shoulder arthroplasty (RTSA) alleviates pain and restores function to patients with cuff tear arthropathies or massive rotator cuff tears. The procedure uses a semi-constrained prosthesis to reverse the orientation of the glenohumeral joint, thereby altering the biomechanics of the …

Development of a two-axis cyclic loading device for mechanical testing of glenoid component fixation
The fundamental mechanism of aseptic glenoid component loosening, the rocking horse phenomenon, is a reaction to glenohumeral articular forces that are not centered on the component. While glenoid component loosening remains a problem, the underlying mechanisms that lead to fixation failure at the …
