AB  - The  biceps  has  two  origins,  crosses  the  shoulder  and  elbow  joints,  and  inserts  on  the  proximal  radius.  The  long  head  is  much  more  susceptible  to  injury,  and  rupture  may  occur  anywhere  along  its  route.  Clinically,  patients  with  proximal  rupture  present  with  pain  along  the  anteromedial  aspect  of  the  shoulder.  On  inspection,  ecchymosis  is  often  acutely  noted.  Muscle  retraction  within  the  arm  may  create  a  “Popeye”  deformity.  Due  to  the  two  proximal  attachments,  the  short  head  of  the  biceps  can  allow  for  maintenance  of  forearm  supination  strength.  Rupture  may  also  occur  at  the  tendon  insertion  into  the  radial  tuberosity  at  the  elbow.  This  diagnosis  is  made  based  on  a  history  of  a  painful,  tearing  or  popping  sensation  in  the  antecubital  region.  The  ability  to  palpate  the  tendon  in  the  antecubital  fossa  may  indicate  partial  tearing.
