Myositis Ossificans Progressiva: A Case Report / 대한정형외과학회잡지

ABSTRACT

Myositis ossificans progressiva is a rare disease characterized by the formation of areas of calcification in the interstitial connective tissue of muscles, tendons, ligaments, fascia, and aponeuroses. There may be exacerbations and remissions of the disease, but the general course is an insidious loss of body motion, affecting especially the neck, spine and upper extremities and, rarely, the hips and lower extremities. It is commonly associated with various congenital anomalies. The cause is unknown and there is no known effective treatment. Myositis ossificans progressiva associated with brachydactyly of both great toes, in a 34 year old femaIe, is presented with a review of the literature. Chief complaints were ankylosis of the left knee and hip of 9 years duration. We performed biopsy of tubular bone which is placed antero-lateral side of the left knee.
