====Elbow injuries====
  *ant fat pad normally seen in children
  *post fat pad NOT usually seen as buried in intercondylar fossa
  *unlikely intra-articular injury if fat pad sign not +ve
  *likely occult # if fat pad sign +ve and # not visible

====Radial head fractures====
^stable |• isolated undisplaced or minimally displaced fracture\\ • nearly always impacted, with intact periosteum, and are unlikely to displace.\\ • **Mx** - conservative. Stiffness is the main adverse outcome and neither immobilisation or early mobilisation are necessarily superior |
^unstable |• usually associated with other bony or ligamentous injury\\ • usually involve several detached, mobile fragments with little or no soft-tissue attachment\\ • often associated with an elbow dislocation, proximal ulna fracture, or injury to the interosseous ligament of the forearm |

^Mason Classification (Modified by Hotchkiss and Broberg-Morrey) |||
^Type I |Nondisplaced or minimally displaced (<2mm), no mechanical block to rotation |{{:wiki:musculoskeletal:upperlimb:radial_head_fracture.png?200|}}|
^Type II |Displaced >2mm or angulated, possible mechanical block to forearm rotation |:::|
^Type III |Comminuted and displaced, mechanical block to motion |:::|
^Type IV |Radial head fracture with associated elbow dislocation |:::|

<wrap em>Essex-Lopresti fracture-dislocation</wrap>
  *fracture of the radial head, dislocation of the distal radioulnar joint and rupture of the antebrachial interosseous membrane
  *possibly only 20% recognised at 1st presentation as XRay may be unremarkable
===Monteggia fracture-dislocation==
  *fracture of the ulnar shaft with concomitant dislocation of the radial head.

^Bado classification of Monteggia fracture-dislocation |||
^I |anterior dislocation of radial head |{{ :wiki:musculoskeletal:upperlimb:bado.jpeg?200|}}|
^II |posterior dislocation of radial head |:::|
^III |lateral dislocation of radial head |:::|
^IV |anterior radial head dislocation as well as proximal third ulnar and radial shaft fractures |:::|
===Galeazzi fracture-dislocation==
  *fracture of the distal part of the radius with dislocation of distal radioulnar joint and an intact ulna.
  *A Galeazzi-equivalent fracture is a distal radial fracture with a distal ulnar physeal fracture.
  *due to a fall on an outstretched hand (FOOSH) with the elbow in flexion
  *type I: dorsal displacement, type II: volar displacement
