title: Post-traumatic myositis ossificans of the sternocleidomastoid following fracture of the clavicle: a case report.
abstract: BACKGROUND
  Fractures of the clavicle are common injuries. The complications have been well documented in the literature.
  
  
  METHODS
  Despite it close proximity to the sternocleidomastoid muscle and myositis ossificans recognised as a known complication of any fracture, the two have never previously been described in association secondary to a fracture of the clavicle. We present a case where myositis ossificans affecting the sternocleiodomastoid was detected in the post-injury phase of a clavicle fracture.
  
  
  CONCLUSIONS
  This case highlights that traumatic myositis ossificans circumscipta can arise in the sternocleidomastoid muscle following a fracture of the medial third of the clavicle.
