   Coronoid fracturesoccur in 10% to 15% of elbow dislocations.  Classified into three types, as described by Regan and Morrey: 1.Type I: -fracture of the intraarticular tip of the coronoid (no long-term instability); 2. Type II: - fracture involving half or less of the coronoid (may significantly affect ulnohumeral stability); 3. Type III: -fracture involving more than half of the coronoid process (often with posterior instability)

  - Because acoronoid fracture fragment may appear small on a lateral radiograph or may be confused with a radial fracture, CT is recommended when a coronoid fracture is suspected. - Displaced coronoid fractures should be reduced and stabilized with fixation. - Careful assessment is mandatory to ensure that the coronoid fracture is not part of a more serious injury (‘terrible triad’).

  Treatment - Sutures canbe used for fixation of small coronoid fracture fragments - And lag screws can be used for larger fragments - A distinct type of coronoid fracture, fracture of the antero- medial facet occurs from a varus force to the elbow and, if left untreated, can result in posteromedial rotary instability. - Repair of the lateral collateral ligament and ORIF of the coronoid are recommended.
