Heterotopic Ossification

সংজ্ঞা

Heterotopic ossification (HO) is the growth of bone in abnormal places like soft tissue. It can occur anywhere in the body. The hip, knees, shoulders and elbows are the most common locations. This condition can vary from minor to heavy growth.

The sooner this condition is treated, the better the outcome. If you suspect you have HO, contact your doctor promptly.

কারণসমূহ

The exact cause of HO is unknown. There may be a genetic link to the development of this condition.

ঝুঁকির কারণ

Although the exact cause is unknown, there are well known factors that increase your chance of getting HO. Tell your doctor if you have any of these risk factors:

• Traumatic brain injury or stroke
• Spinal cord injury (especially recent, 1-4 months)
• Hip surgery or other joint surgery
• পোড়া
• Long period of immobility
• Joint infection
• Trauma to muscle or soft tissue

লক্ষণ

Symptoms vary based on the severity and site of the bone growth. If you have any of these, do not assume it is due to HO. These symptoms may be caused by other conditions. Tell your doctor if you have any of these:

• Decreased range of motion
• Swelling or redness to joint(s)
• ব্যাথা
• জ্বর

রোগ নির্ণয়

Your doctor will ask about your symptoms and medical history. A physical exam will be done. You may be referred to a specialist. An orthopedic doctor focuses solely on problems of the bones and joints.

পরীক্ষায় নিম্নলিখিতগুলি অন্তর্ভুক্ত থাকতে পারে:

• Bone scan —a test that determines mineralization of the bones and detects abnormal bone in tissue
• Serum alkaline phosphatase level—increased levels of this substance in the blood is linked to heterotopic ossification
• Several tests have been studied for HO. These are used less often and include:
  • Serum osteocalcin
  • C-reactive protein
  • Erythrocyte sedimentation rate
  • Creatine kinase
  • Urine hydroxyproline, deoxypyridinoline, and prostaglandin
• X-ray —may only be able to detect abnormal bone in later phases of the disease
