What means heterotopic?
What means heterotopic?
Heterotopic: In the wrong place, in an abnormal place, misplaced. From the Greek roots “hetero-” meaning “other” + “topos” meaning “place” = other place. For example, heterotopic bone formation is the formation of bone where it is not normally found, as in muscle.
What are heterotopic bones?
Heterotopic ossification (HO) is the presence of bone in soft tissue where bone normally does not exist. The acquired form of HO most frequently is seen with either musculoskeletal trauma, spinal cord injury, or central nervous system injury.
How is heterotopic ossification diagnosis?
Radiographs are most often the first imaging study used to detect nongenetic HO and often have distinctive features that allow diagnosis. Unusual roentgenographic findings should prompt a second imaging modality. In the early phases of HO, no ossification can be found by radiographs.
What are the causes of heterotopic ossification?
Causes. 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.
What is treatment for heterotopic ossification?
Patients with a high risk of developing HO are often given prophylactic treatment following primary or revision arthroplasty. All patients undergoing excision of symptomatic HO should also receive some form of prophylaxis. The two main treatments available are radiation therapy and NSAIDs.
What is a heterotopic transplant?
Heterotopic heart transplantation (HHT) is a surgical procedure that allows the graft to be connected to the native heart in a parallel fashion. The main advantage of HHT is to assist the patient’s native heart and to maintain circulation in the cases of severe acute rejection.
Is heterotopic ossification painful?
Heterotopic Ossification (HO) is the abnormal growth of bone in the non-skeletal tissues including muscle, tendons or other soft tissue. When HO develops, new bone grows at three times the normal rate, resulting in jagged, painful joints.
Can heterotopic ossification be treated?
Is heterotopic ossification serious?
If the cause of pain or discomfort is not found and treated immediately, serious complications, such as stroke, seizure, organ damage, permanent brain injury or even death, may occur. Autonomic dysreflexia can occur with HO as the abnormal bone growth causes pain that the brain doesn’t recognize because of SCI.
Can a woman’s heart be transplanted into a man?
The problem is not that women’s hearts won’t work in men. It’s that a smaller heart won’t work well in a larger body. “It’s far more important to size properly — regardless of sex,” said Stephanie Moore, MD, a cardiologist at the Massachusetts General Hospital (MGH) Cardiac Transplant Program in Boston.
How common is heterotopic ossification?
Heterotopic ossification is a common complication of total hip arthroplasty. Its prevalence is not the same in all of the patient groups. Frequency of HO varies from 15 to 90%.
What doctor treats heterotopic ossification?
When heterotopic ossification (HO) is severe or problematic and causes pain, or affects a patient’s mobility and function, it should be managed by an orthopaedic surgeon. Occasionally, that involves surgery or a revision procedure to resolve the problem.
Can you fix heterotopic ossification?
For now, the only way to treat heterotopic ossification is to wait for it to stop growing and cut it out which never completely restores joint function.
