Heterotopic OssificationHeterotopic Ossification – General InformationHeterotopic Ossification is considered a bone formation inside the patient’s osseous tissues. This kind of bone disorder usually develops after the patient suffers from a certain trauma such as fractures and surgical procedures. In case that Heterotopic Ossification affects the patient’s hip, its considered a complication of the total hip arthroplasty. The condition can also appear due to neurological diseases such as spinal cord and brain injury. Scientists have not determined an exact cause of the condition, but they say that the pluripotential mesenchymal cells differentiate into osteoblasts, thus causing the disorder; researchers try to determine the source of the mesenchymal cells or the factor that causes them to differentiate. These cells are thought to originate from the bone itself, bone marrow or even the patient’s muscle. The scientists also discovered that a certain inducing substance, for example, bone morphogenetic protein, is responsible for the cells differentiation. This process takes place after approximately 16 hours after the surgical procedure. Generally, in the acute stage of Heterotopic Ossification, the cells infiltrate and cause edema and degeneration of the patient’s muscle. After several weeks, the inflammation is replaced with bone tissue. There are certain risk factors that lead to the appearance of this condition and can include ossification in the ipsilateral or contralateral hip, hypertrophic osteoarthritis, ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. The male patients are more prone to develop the condition than female patients. There are cases in which the condition does not affect only the hip, but also the shoulder and joints.Heterotopic Ossification – SymptomsHeterotopic Ossification usually appears after 2 weeks after the patient has suffered from certain trauma, such as surgical procedures or fractures. Generally, the ectopic bone matures in eight months after the injury. After the condition has developed, the patient can experience swelling and tenderness, signs that can be similar to a low grade infection. The condition appears on radiographs only after four to six weeks after the trauma, due to the bone mineralization. There are certain risk factors that lead to the appearance of this bone condition and can include ossification in the hypertrophic osteoarthritis, contralateral or ipsilateral hip, ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. The symptoms caused by Heterotopic Ossification are more complicated, due to the improper care. The most common signs of the condition can include paralysis and loss of sensation, which can develop depending on each individual in the patient’s head, neck, chest, shoulders, arms, hands, abdomen, buttocks, genitals, legs and muscles of the perineum; deep venous thrombosis, when the blood does not flow normally to the paralyzed part of the body; pressure ulcers, caused also by the inability to move; spasticity and contracture, autonomic dysreflexia, which is most often in knees and hips; loss of bladder and bowel control and sexual dysfunction, when the patient can not achieve an erection or ejaculation. The gravity of the symptoms depends on the part of the body that has been affected. It is very important to treat the condition in an early stage to decrease the risk of developing more severe complications.Heterotopic Ossification – TreatmentThere are three major treatment options for Heterotopic Ossification and can include surgery, radiation therapy and non-steroidal anti inflammatory drugs. The surgical approach for this kind of medical condition is considered the most effective treatment option of all. The delay of the surgery by several months, to allow the bone to mature, also allows the inflammatory phase of the condition to resolve, fact that minimizes trauma to the patient’s tissue and decreases the risk of recurrence. It is very important to be careful during the surgical operation to avoid injuring the surrounding tissues. If the operation is not done properly, this medical disorder of the bones - Heterotopic Ossification, can progress to a more severe form, also known as trochanteric osteotomy. Due to the fact that the surgical procedure is essential in establishing the disease, it is recommended to prevent the appearance of the heterotopic bone. The prevention starts by avoiding injuries to the surrounding soft tissues. To prevent the heterotopic bone to form, doctors can use radiation therapy and certain drugs. The radiation therapy used to treat Heterotopic Ossification consists in radiation of the pluripotential mesenchymal cells, the cells that generally cause the condition. There is a high risk to develop secondary malignancies when the radiation therapy is administered in high doses. The normal dose that is enough to prevent the condition can consist in 10 Gy in 5 fractions. There are also some particular cases, with advanced condition, in which the doctors apply a dose of 20 Gy in 5 fractions. In applying the radiation therapy, timing is of great significance, and normally, the radiation should be administered in 72 hours after the surgical procedure. After these hours, the mesenchymal cells become differentiated and the bone matrix becomes synthesized, and the growth rate of the heterotopic bone increases. There are many cases of treatment failures due to the bad timing. In some cases, preoperative radiation therapy is required to decrease the rate of dividing cells such as mesenchymal cells, which are usually sensitive to the surgery. There are also some cases in which the doctors have to replace the patient’s failed hip prostheses. In these cases, the radiation therapy is repeated to decrease the risk of Heterotopic Ossification recurring. The radiation therapy option usually does not cause any side effects, but several complications and impaired healing can appear after the surgical procedure. If the therapy is not administered properly, the disease can progress to the more severe trochanteric osteotomy condition. If the radiation is administered efficiently, the risk of developing neoplasm is also reduced. Another way to treat Heterotopic Ossification condition is the use of non-steroidal anti inflammatory drugs, especially indomethacin, which has proved to be the most efficient. These medicines have the effect of suppressing the migration and reproduction of the inducible mesenchymal cells. The normal dose of non-steroidal anti inflammatory drugs is 50 mg per day for maximum effects. The bad part about these medicines is that they cause side effects, which can include gastrointestinal ulceration, decreased platelet aggregation and renal toxicity. |
