AB The  shoulder  complex,  composed  of  the  clavicle,  scapula,  and  humerus,  is  an  intricately  designed  combination  of  three  joints  that  links  the  upper  extremity  to  the  thorax.  The  articular  structures  of  the  shoulder  complex  are  designed  primarily  for  mobility,  allowing  us  to  move  and  position  the  hand  through  a  wide  range  of  space.  The  glenohumeral  (GH)  joint,  which  links  the  humerus  and  scapula,  has  greater  mobility  than  any  other  joint  in  the  body.  Although  the  components  of  the  shoulder  complex  constitute  half  of  the  mass  of  the  entire  upper  limb,1  they  are  connected  to  the  axial  skeleton  by  a  single  joint,  the  sternoclavicular  (SC)  joint.  As  a  result,  muscle  forces  serve  as  a  primary  mechanism  for  securing  the  shoulder  girdle  to  the  thorax  and  providing  a  stable  base  of  support  for  upper  extremity  movements.
