Design Optimization and Prosthesis Classificationization analysis in which 32 different geometric iterations of the Grammont reverse shoulder were evaluated to identify parameters that minimize scapular impingement while maximizing range of motion and stability. Specifically, humeral neck angle, humeral stem/liner offset, humeral liner constraint,雄辩 发表于 2025-3-28 19:22:33
Motion and Muscular Function After Reverse Shoulder Arthroplasty such prostheses have limited internal and external rotation, they do not achieve full elevation, and they have difficulties to lift even lightweight objects above the shoulder level. These problems are related to the lack of rotator cuff function and to the particular design of reverse prostheses.飓风 发表于 2025-3-28 23:56:12
Biomechanics of the Normal and Reverse Shoulderlane. The peak force developed by the deltoid during scapular-plane abduction is around 8 times the weight of the upper limb, while the peak force transmitted across the glenohumeral joint is estimated to be around 13 times the weight of the upper limb .

Biomechanics of Reverse Shoulder Arthroplasty: Contribution of Computer Modelinge reverse prosthesis constrains the articular surfaces and displaces medially the joint rotation center. The gain in stability and muscle moment arms is counterbalanced by impingements that reduce the shoulder mobility. From a biomechanical perspective, reverse shoulder prostheses are thus deeply di旋转一周 发表于 2025-3-29 16:21:49
Kinematic Analyses of Patients with Reverse Shoulder Arthroplastyof 2:1. However, it was demonstrated that two-dimensional methods fail to account for “out-of-plane” motions; therefore a 3-dimensional system, especially an electromagnetic system, seems to be the most suitable method to register the three-dimensional movement of the shoulder. By using the “Flock o灌溉 发表于 2025-3-29 19:43:48

Massive Rotator Cuff Arthropathy with Glenohumeral Arthritisically, this disease process was frustrating and difficult to treat, with patients hoping to achieve what Charles Neer described as “limited goals” for functional outcomes. The introduction of RSA has revolutionized the treatment of CTA providing reliable and reproducible improvements in pain, funct
