AB  - Imaging  of  the  elbow  includes  assessment  of  the  three-joint  complex:  humeroulnar,  humeroradial,  and  proximal  radioulnar.  The  function  of  these  three  joints  is  to  allow  the  hand  to  be  positioned  to  enable  the  desired  actions  to  be  accomplished.  The  distal  humerus  provides  medial  (trochlea—articulates  with  ulna)  and  lateral  (capitulum  or  capitellum—articulates  with  radius)  articular  areas  of  their  respective  condyles  (Figure  12-1).  Three  concavities  (fossae)  are  present,  two  anteriorly—coronoid  (accepts/articulates  with  ulna  in  flexion)  and  radial  (accepts/articulates  with  radius  in  flexion)—while  there  is  one  posteriorly—olecranon  (accepts/articulates  with  the  olecranon  process  of  the  ulna  in  extension).  The  most  proximal  radius  is  composed  of  the  head,  which  includes  a  cup-like  superior  projection  to  articulate  with  the  capitulum,  while  the  circumferential  surface  articulates  with  the  radial  notch  of  the  ulna.  The  remaining  proximal  radius  is  composed  of  the  bicipital  tuberosity  and  the  neck.  The  medial  and  lateral  epicondyles  of  the  humerus  serve  as  insertional  sites  for  ligaments  and  tendons.
