<prompt> Which of the following movements will be affected if the greater tubercle of the humerus is lost -Abduction and lateral rotationAdduction and flexionAdduction and medial rotationFlexion and medial rotation  <response>: Muscles attached to greater tuberosity are.Supraspinatus: - Helps in the initial range of abduction.Infraspinatous, Teres minor : - External lateral rotation.Therefore, these movements are affected in fracture greater tuberosity.Muscle attached to lesser tuberosity is subscapularis an internal or medial rotator of shoulder joint. So, movement affected in lesser tuberosity fracture is an internal rotation.
