  1. 1. MYOSITIS OSSIFICANS By: Laycee and Sara F.
  2. 2. INTRODUCTION  Have you ever heard of Myositis Ossificans? Do you know of anyone who has this condition?  In this presentation we are going to inform you on this condition by telling you what it is, the risk factors involved, the different types, signs and symptoms, how to prevent a person from getting it, how to diagnose a patient, and the proper management needed to help the patient relieve his/her symptoms and prevent further injury.
  3. 3. WHAT IS MYOSITIS OSSIFICANS  Myositis ossificans and heterotopic ossifican are often used interchangeably to describe the formation of bone in atypical location of the body.  Myositis ossificans is an unusual condition that often occurs in people who sustain a blunt injury that causes damage to the sheath that surrounds a bone (periostium) as well as to the muscle and deep tissue. The soft-tissues that were injured in the traumatic event initially develops a hematoma, and subsequently develop the myositis ossificans. The word myositis ossificans means that bone forms within the muscle, and this occurs at the site of the hematoma. The bone will grow 2 to 4 weeks after the injury and be mature bone within 3 to 6 months. No one knows exactly why this occurs in some people.  Myositis ossificans can occur in any collagenous supportive tissue of skeletal muscles, tendons, ligaments, and fascia.
  4. 4. RISK FACTORS OF MYOSITIS OSSIFICANS  Serious traumatic injury  Previous history of ossificans  Hypertrophic osteoarthritis  Ankylosing spondylitis  Diffuse idiopathic skeletal hyperostosis  Men at higher risk  Paget’s disease  Rheumatoid arthritis  Posttraumatic arthritis  Neural axis  Thermal injuries  Osteonecrosis  Multiple surgeries in a short period of time  Burn injuries  Not applying cold therapy and compression immediately after the injury.  Having intensive physiotherapy or massage too soon after the injury.  Returning too soon to training after exercise.
  5. 5. TYPES OF MYOSITIS OSSIFICANS  Myositis ossificans progressiva  Myositis ossificans paralytica  Myositis ossificans circumscripta  Myositis ossificans traumatica
  6. 6. SIGNS AND SYMPTOMS  Muscle weakness  Rigid Muscles  Tendon weakness  Rigid tendons  Restricted ROM  Pain in muscle when you use it  Tenderness  Skin swelling over calcified site  Shortened digits  Skeletal malformations  Malformed fingers  Malformed toes  Limited joint movement
  7. 7. PREVENTION  Parmaceutricals  NSAIDs  Diphosphonates  Radiation Treatment  Low dose beam radiation
  8. 8. HOW DO YOU DIAGNOSE MYOSITIS OSSIFICANS?  Radiography  Bone scanning  Ultrasounography  CT Scan  Disadvantages:  Radiographs cannot detect mineralization during the first 1-2 weeks after the inciting trauma or onset of symptoms.  Radiography nor CT scanning should be performed in the pelvic region during pregnancy
