Definition/Description[edit | edit source]
Fibrodysplasia Ossificans Progressiva is a rare, genetic disorder than transforms ligaments, muscles and tendons into bone outside the skeleton that impairs movement.
Prevalence[edit | edit source]
- 1 in every 2 million people are diagnosed with Fibrodysplasia Ossificans Porgressiva
- Nearly 90% of the time it is misdiagnosed and mismanaged. (Lakkrieddy)
- 67% undergo invasive procedures for diagnosis and treatment
- More than 50% end up with lifelong disabilities
- Mostly occurs in children
Characteristics/Clinical Presentation
[edit | edit source]
- Hearing impairments in approximately 50% of patients
- Pneumonia and right sided heart failure
- Controversial malformations
- Ossification of intercostal muscles
- Kyphoscoliosis and lordosis
- Severe weight loss
- Torticollis
- TMJ complications
Medications[edit | edit source]
For acute flare-ups:
- short term high does corticosteroids
- NSAIDS
- Biophosphonates
- Radiotherapy
Diagnostic Tests/Lab Tests/Lab Values[edit | edit source]
Blood samples
- Indicate presense of heterozygous R206H mutation of the ACVR1 gene
Etiology/Causes[edit | edit source]
- Genetic R206H mutation of the ACVR1 gene
- ACVR1 gene is a bone morphogenetic protein (BMP) type1 receptor signaling endochondral ossification
- R206H mutation leads to an increase in enhanced BMP signaling
- Confirmation of a heterozygous gene mutation of the ACVR1 gene
Systemic Involvement[edit | edit source]
Cardiopulmonary system
- Lungs affected caused by thoracic insufficiencies
- Restrictive pulmonary diseases
Nervous system
- Middle ear ossifications
- Hearing impairments
Medical Management (current best evidence)[edit | edit source]
Medications
- Reduces the pain and severity of flare-ups
Surgical release of joint contractures
- Usually unsuccessful
Osteotomy of heterotropic bone
- Mobilizes joints
- Usually counterproductive because new heterotrophic ossificans can form at the site
Repositioned surgically
- Improves the patients overall functional status
- Rare
Ultimately, there is not much that can be done to cure this disease.
