Q:
What is arthrosis?
A:
Arthrosis refers to various types of bone and joint diseases, including:
- degenerative arthritis,
- bursitis,
- synovitis,
- cervical spondylosis,
- lumbar spondylosis,
- frozen shoulder,
- bone hyperplasia,
- rheumatoid arthritis,
- rheumatoid arthritis,
- femoral head necrosis.
The root cause of the disease is not the bone lesions, but the loss of ability of “joint protection system” such as cartilage, according to modern medical researches.
Clinical manifestations of arthrosis are as follows:
- The main symptom is joint pain. Joint pain occurs when the joints move and disappears or improves after the break. In acute exacerbations, the pain gets worse, and joint swelling, joint stiffness, and intra-articular friction can be observed.
- If some patients have their joints stay in a certain position for too long, they may feel joint pain, which is called rest pain. After the patient has gradually moved the joint for a certain period of time, the pain disappears, and the joint can feel loose.
- Hyperplastic bones stimulate or compress adjacent nerves to cause radiation pain, such as upper limb pain caused by cervical vertebra hyperplasia, lower limb pain caused by lumbar hyperplasia, and anterior medial pain caused by hip hyperplasia.
- There is no abnormality in the shape and movement of the joints in the early stage. However, thickening of the bones, joint swelling, muscle atrophy and joint deformation may occur in the joints with less soft tissues around the knees and fingers in severe conditions.
Key words: arthrosis; clinical manifestations of arthrosis.
