Vahid Entezari

About

Vahid Entezari is a leading researcher in orthopedic biomechanics, with a focused expertise in shoulder kinematics and the mechanical effects of injury on the glenohumeral joint. His work is foundational in understanding how scapular positioning and rotator cuff pathology alter joint stability and motion, particularly in the context of athletic throwing. Entezari’s major contributions include the design and manufacture of a novel robotic system capable of simulating complex, three-dimensional shoulder motion, including basic and pitching movements. This apparatus, detailed in his 2012 work (16 citations), overcomes the limitations of traditional cadaveric models by enabling the study of passive glenohumeral kinematics in a more physiologically relevant manner. Using this system, his research has demonstrated the critical impact of simulated scapular winging on joint translations (2013, 21 citations) and quantified how supraspinatus tears disrupt glenohumeral mechanics during pitching motion (2014, 15 citations). These findings provide essential data for improving surgical repair techniques and rehabilitation protocols. Through his innovative robotic modeling and precise kinematic analysis, Entezari has significantly advanced the field’s ability to link specific shoulder pathologies with measurable mechanical dysfunction.
