-
- Myositis Ossificans is a rare progressive disorder marked by bone tissue-like
- formations (calcifications) which occur inside skeletal muscles. Stiffening
- or weakening of muscles may occur where calcifications are found. Other signs
- of this disorder may include shortened fingers or toes and curvature of the
- spine (scoliosis). Very rarely patients may experience deafness, baldness or
- mental retardation with this disorder.
-
- Symptoms
-
- Myositis Ossificans causes progressive weakening or stiffening of muscles
- where abnormal bone tissue-like formation (calcification) has occurred.
- Bands of tissue connecting muscles together, tissues connecting tendons to
- muscles, and tendons, may also become weak or stiff. Pain and tenderness
- during contraction of muscles is common. In some cases, swelling resembling
- bruises may appear on the skin at the site of calcifications.
-
- In later stages, progression of the disorder may be unpredictable.
- Curvature of the spine (scoliosis) can occur. In the most serious cases, the
- ability to walk may be limited. Deafness, baldness or mental retardation may
- occur as rare symptoms of this disorder.
-
- Causes
-
- Myositis Ossificans is suspected to be inherited as a dominant trait. A
- non-hereditary disorder with similar muscle involvement consists of
- calcifications resulting from muscle injuries. (Human traits including the
- classic genetic diseases, are the product of the interaction of two genes for
- that condition, one received from the father and one from the mother. In
- dominant disorders, a single copy of the disease gene (received from either
- the mother or father) will be expressed "dominating" the normal gene and
- resulting in appearance of the disease. The risk of transmitting the disorder
- from affected parent to offspring is 50% for each pregnancy regardless of the
- sex of the resulting child.)
-
- Affected Population
-
- Only approximately 350 cases of Myositis Ossificans have been described in
- medical literature in this century. This disorder usually appears before ten
- years of age. Myositis Ossificans seems to affect males and females in equal
- numbers.
-
- Related Disorders
-
- The following diseases are similar to Myositis Ossificans. Comparisons may
- be useful for a differential diagnosis.
-
- A variant of Myositis Ossificans involves calcifications developing as a
- result of muscle injury which may not be related to genetic factors.
-
- Pseudohypoparathyroidism (Martin-Albright Syndrome) is also known as
- Seabright-Bantam Syndrome. This disorder is inherited as an X-linked trait.
- Although normal amounts of the parathyroid hormone are present, inadequate
- response to the hormone affects bone growth in Pseudohypoparathyroidism
- patients. Headaches, weakness, tiring easily, lethargy and blurred vision or
- sensitivity to light can occur. Unusual sensations, stiffness or cramps in
- arms or legs, palpitations and abdominal pain may be noticed. A round face,
- thick short stature, shortened fingers or toes, and mental deficiencies are
- also found in patients with Martin-Albright Syndrome. The prognosis is good
- for most patients. Hormonal and calcium replacement therapy is often useful,
- but the lack of growth may persist.
-
- Calcinosis Universalis is a skin disorder with sore or tender skin due to
- excess calcium deposits. This progressive disorder can appear at any age.
- The skin lesions may be accompanied by calcium deposits around joints or in
- muscles. This may lead to muscle weakness and swelling. The kidneys,
- stomach or lungs may also have calcium deposits. The prognosis depends on
- the degree of involvement and treatment of associated infections.
-
- The following disorders may be associated with Myositis Ossificans as
- secondary characteristics. They are not necessary for a differential
- diagnosis.
-
- Scoliosis is a curvature of the spine often developing in pre- and early
- adolescence. A common disorder in the United States, it tends to affect more
- girls than boys. One form of Scoliosis is believed to be hereditary.
- Screening for Scoliosis is often a part of the normal physical examination
- provided annually to children. Early detection is helpful in stopping
- progression of the disorder. (For more information on Scoliosis, please
- contact the National Scoliosis Foundation. The address is listed in the
- Resources Section of this report).
-
- Therapies: Standard
-
- Symptoms of Myositis Ossificans can usually be treated without surgery. Use
- of steroid drugs and xylocaine (lidocaine) may reduce inflammation and muscle
- stiffness. Use of antibiotics to treat infections is often helpful. Surgery
- or biopsy of calcifications may sometimes worsen symptoms; surgery should be
- performed only in the most severe cases. Intramuscular injections, muscle
- injury, careless puncture of a vein or dental surgery may also make
- calcifications more severe.
-
- Other treatment is symptomatic and supportive. Agencies and programs
- which assist handicapped individuals may be helpful to patients and their
- families. Families with the hereditary form of Myositis Ossificans can
- benefit from genetic counseling.
-
- Therapies: Investigational
-
- Sonotomography, X-ray and scintigraphy are all imaging procedures being
- tested to accurately pinpoint and monitor the size of calcifications in
- muscles in Myositis Ossificans. Sonograms are graphic representations of
- deep structures of the body using echoes of pulses of high frequency sound
- waves directed at the tissues. Scintigraphs are photographic two-dimensional
- maps of gamma ray concentration in specific tissues of the body. Imaging
- procedures are used at regular intervals to determine whether calcifications
- continue to grow.
