How is hypertrophic osteoarthropathy diagnosed?
The diagnostic criteria for hypertrophic osteoarthropathy (HOA) include clubbing and periostosis of the tubular bones. Three incomplete forms of hypertrophic osteoarthropathy are described: Clubbing alone. Periostosis without clubbing in the setting of an illness known to be associated with HOA.
What causes hypertrophic osteoarthropathy?
Hypertrophic osteoarthropathy (HOA) is mainly caused by mainly fibrovascular proliferation. It is characterized by a combination of clinical findings, including severe disabling arthralgia and arthritis, digital clubbing, and periostosis of tubular bones with or without synovial effusion.
What is hypertrophic bone formation?
They defined hypertrophic bone formation as bony regrowth of 3 mm or greater, which they noted at the site of a surgical resection or osteotomy of bone.1. What Studies Reveal About The Risk Factors. The etiology of hypertrophic bone formation is largely unknown.
What is hypertrophic osteoarthropathy multiple sites?
Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints. Distal expansion of the long bones as well as painful, swollen joints and synovial villous proliferation are often seen.
What is primary hypertrophic osteoarthropathy?
The primary hypertrophic osteoarthropathy (pachydermoperiostosis) is a hereditary disease characterized by skin thickening (pachydermia), finger clubbing, and proliferation of periosteum (periostitis) with subperiosteal new bone formation.
How is hypertrophic osteoarthropathy treated?
Primary hypertrophic osteoarthropathy Medical care is palliative and includes nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, tamoxifen, retinoids, and risedronate to alleviate the painful polyarthritis/osteoarthropathy. Colchicine may be helpful for the pain due to subperiosteal new bone formation.
What is hypertrophic osteoarthropathy?
Hypertrophic osteoarthropathy (HOA) is a medical condition characterized by abnormal proliferation of skin and periosteal tissues involving the extremities and characterized by three clinical features: digital clubbing (also termed Hippocratic fingers), periostosis of tubular bones, and synovial effusions.
What is hypertrophic bone changes?
Hypertrophic osteoarthropathy is a disorder characterized by bilateral symmetrical subperiosteal new bone formation at the ends of long bones. Most commonly but not exclusively, the condition is associated with destructive chronic lung disease or lung tumors.
What is hypertrophic arthritis?
hypertrophic arthritis rheumatoid arthritis marked by hypertrophy of the cartilage at the edge of the joints; osteoarthritis.
Can Osteoarthropathy be cured?
In fact, hypertrophic osteoarthropathy may disappear completely by 3-6 months. Thus, in cases where the primary cause can be treated, symptoms of hypertrophic osteoarthropathy most likely improves or resolves.
What causes hypertrophic bone formation?
Between 80 and 90% of secondary hypertrophic osteoarthropathy is associated with non–small cell lung cancer. Other causes include other neoplasms (mesothelioma), chronic pulmonary infections, congenital heart disease, cirrhosis, HIV infection, and inflammatory bowel disease.
What are the clinical features of hypertrophic osteoarthropathy?
Hypertrophic osteoarthropathy (HOA) is a medical condition characterized by abnormal proliferation of skin and periosteal tissues involving the extremities and characterized by three clinical features: digital clubbing (also termed Hippocratic fingers), periostosis of tubular bones, and synovial effusions.
Is there a difference between clubbing and hypertrophic osteoarthropathy?
However, clubbing is easily overlooked on physical examination, and hypertrophic osteoarthropathy is often mistaken for some other disorder. The diagnosis of clubbing is based on the finding of an increase in the soft tissue at the base of the finger or toenails.
How is periostitis related to hypertrophic osteoarthropathy?
Typically seen as long bone metaphyseal and diaphyseal smooth periosteal reaction. With disease progression, periostitis becomes more prominent or multilayered and extends to the epiphyses 1. The success of treatment depends on whether the hypertrophic osteoarthropathy is due to a primary or a secondary cause.
How are NSAIDs used to treat hypertrophic osteoarthropathy?
In primary hypertrophic osteoarthropathy (or in cases where the underlying condition could not be treated), symptomatic relief can be obtained by use of NSAIDs, corticosteroids or bisphosphonates 6,7. General imaging differential considerations include: Consider the differential for a smooth periosteal reaction.
