    • Bulk effect of the deltoid muscle on the glenohumeral joint 

      Rosso, Claudio; Mueller, Andreas M; McKenzie, Brett; Entezari, Vahid; Cereatti, Andrea; Croce, Ugo Della; Ramappa, Arun J; Nazarian, Ara; DeAngelis, Joseph P (Springer Berlin Heidelberg, 2014)
      Background: There remains controversy on the role of the deltoid on glenohumeral translations during basic and pitching motions. We thus studied the passive effect of the deltoid on the deltoid glenohumeral joint center ...

    • Design and manufacture of a novel system to simulate the biomechanics of basic and pitching shoulder motion 

      Entezari, V.; Trechsel, B. L.; Dow, W. A.; Stanton, S. K.; Rosso, C.; Müller, A.; McKenzie, B.; Vartanians, V.; Cereatti, A.; Della Croce, Ugo; DeAngelis, Joseph; Ramappa, Arun Jogi; Nazarian, Ara (British Editorial Society of Bone and Joint Surgery, 2012)
      Objectives: Cadaveric models of the shoulder evaluate discrete motion segments using the glenohumeral joint in isolation over a defined trajectory. The aim of this study was to design, manufacture and validate a robotic ...

    • Glenohumeral Joint Kinematics following Clavicular Fracture and Repairs 

      Rosso, Claudio; Nasr, Michael; Walley, Kempland C.; Harlow, Ethan R.; Haghpanah, Babak; Vaziri, Ashkan; Ramappa, Arun J.; Nazarian, Ara; DeAngelis, Joseph P. (Public Library of Science, 2017)
      Background: The purpose of this biomechanical study was to determine the effect of shortened clavicle malunion on the center of rotation of the glenohumeral (GH) joint, and the capacity of repair to restore baseline ...

    • Influence of disruption of the acromioclavicular and coracoclavicular ligaments on glenohumeral motion: a kinematic evaluation 

      Walley, Kempland C.; Haghpanah, Babak; Hingsammer, Andreas; Harlow, Ethan R.; Vaziri, Ashkan; DeAngelis, Joseph P.; Nazarian, Ara; Ramappa, Arun J. (BioMed Central, 2016)
      Background: Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide ...

    • Posterior Capsular Plication Constrains the Glenohumeral Joint by Drawing the Humeral Head Closer to the Glenoid and Resisting Abduction 

      DeAngelis, Joseph P.; Hertz, Benjamin; Wexler, Michael T.; Patel, Nehal; Walley, Kempland C.; Harlow, Ethan R.; Manoukian, Ohan S.; Masoudi, Aidin; Vaziri, Ashkan; Ramappa, Arun J.; Nazarian, Ara (SAGE Publications, 2015)
      Background: Shoulder pain is a common problem, with 30% to 50% of the American population affected annually. While the majority of these shoulder problems improve, there is a high rate of recurrence, as 54% of patients ...

    • Preliminary evaluation of a robotic apparatus for the analysis of passive glenohumeral joint kinematics 

      Rosso, Claudio; Müller, Andreas M; Entezari, Vahid; Dow, William A; McKenzie, Brett; Stanton, Stacey K; Li, Daniel; Cereatti, Andrea; Ramappa, Arun J; DeAngelis, Joseph P; Nazarian, Ara; Croce, Ugo Della (BioMed Central, 2013)
      Background: The shoulder has the greatest range of motion of any joint in the human body. This is due, in part, to the complex interplay between the glenohumeral (GH) joint and the scapulothoracic (ST) articulation. ...
