Myositis Ossificans By: Laycee and Sara F.
Introduction Have you ever heard of MyositisOssificans? 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.
What is Myositis Ossificans Myositis ossificans and heterotopicossifican 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.
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.
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
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
Management Acute Phase: first 1 to 2 weeks Inflammatory Phase: 2 to 6 weeks Fibrotic Phase: 6 to 12 weeks Recovery Phase: 3 to 6 months Surgery
