title: Ultrasonography and radiography to identify early post traumatic myosistis ossificans in an 18-year-old male: a case report.
abstract: OBJECTIVE
  The purpose of this case report is to describe a patient with post traumatic myositis ossificans (PTMO) of the anterior thigh following blunt trauma and discuss the incidence, clinical presentation, management, and imaging findings.
  
  
  METHODS
  An 18-year-old male presented to a chiropractic clinic with a chief complaint of left knee pain and reduced range of motion after an impact injury to his left anterior thigh during hurdling 6 weeks earlier. Immediately after the injury, he presented to the emergency department where radiography of the left knee was negative and he was diagnosed with a muscle sprain. Follow-up radiography and ultrasonography of the left knee in a chiropractic radiology department revealed ossification consistent with PTMO within his vastus intermedius.
  
  
  RESULTS
  The patient underwent a course of rehabilitation for 2 months including ice, class IV cold laser and vibration applied to his anterior thigh, and myofascial release of his quadriceps musculature with targeted and progressive rehabilitative exercises. His left knee pain resolved within 2 weeks of care. He resumed sports participation (American football) pain-free, while wearing protective padding over the affected thigh, 1 month after presentation, which was approximately 2 1/2 months following his injury.
  
  
  CONCLUSIONS
  This case demonstrates that ultrasonography may have the capability to detect early phases of PTMO approximately 2 weeks prior to radiographic evidence and to monitor progression throughout its course.
