Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic.
Progressive osseous heteroplasia is a cutaneous condition characterized by cutaneous or subcutaneous ossification. [1] According to the Progressive Osseous Heteroplasia Association: Progressive Osseous Heteroplasia (POH) is a rare genetic condition in which the body makes extra bone in locations where bone should not form.
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
Since osteoporosis causes loss of bone mineral density, it makes bones more prone to breaking in the event of a hip injury. Hip Impingement Hip impingement is caused by a congenital abnormality.
Myositis ossificans comprises two syndromes characterized by heterotopic ossification (calcification) of muscle. In 2020, the World Health Organization classified myositis ossificans together with fibro-osseous pseudotumor of digits as a single specific entity in the category of fibroblastic and myofibroblastic tumors .
Heterotopic ossification is a process resulting in the formation of bone tissue that is often atypical, at an extraskeletal location. Calcification is often confused with ossification. Calcification is synonymous with the formation of calcium -based salts and crystals within cells and tissue .
It was not until 1937 when the first heterotopic ossification symptom surfaced. By the time of his death, Eastlack's skeleton bore sheets of bone along the vertebrae that fused to and locked his skull, and branches of bone along his limbs, which immobilized his shoulders, elbows, hips, and knees.

The risks of infection and blood clots are always present, and Ganz and his colleagues cite complications such as heterotopic ossification (new bone formation around the hip), nerve injuries, failure of the greater trochanter to heal back properly, persistent pain following the formation of scar tissue in the hip joint, and a small risk of ...
