Basic Information
Etiology of osteochondroma
- The cause of osteochondroma is not clear, it may be caused by congenital endosperm defects; misplacement of the epiphyseal plate; gradually formed from residual immature cells or metaplastic chondrocytes in the inner layer of the periosteum. Osteophyte; Incomplete growth of the periosteum cannot restrain the growth of patellar cartilage and cause deformity of cartilage to form osteophyte; During the growth of the bone, the metaphyseal loses its ability to co-shape, which widens and continuously proliferates to form bone (6) Metabolic disorders of acidic mucopolysaccharides and other factors.
Clinical manifestations of osteochondroma
- The main clinical manifestations of osteochondroma are joint pain, swelling, weakness, and progressive dysfunction. Interlocking and severe pain can occur, and rest or limb braking can be automatically unlocked. In some patients, the free body that can be easily touched can be touched in the supracondylar sac, and there is a sound on examination, and atrophy of the quadriceps can be seen.
Osteochondroma test
- X-ray examination of osteochondroma disease can be seen in the early stage of the disease, or the calcification of the free body is unclear, and arthroscopic imaging can help diagnosis; multiple small circular shadows can be seen after the calcification of the free body, which can be confirmed by arthroscopy.
Diagnosis of osteochondroma
- Diagnosis is based on clinical manifestations and imaging evidence. The disease should be distinguished from osteochondroma with sarcoma.
Osteochondroma disease treatment
- The only way to treat osteochondroma is surgery. Remove the free body as clean as possible, remove the diseased synovium, retain healthy parts, reduce joint movement disorders, and remove severe parts of the disease in those with obvious osteoarthritis; in severe patients, arthroplasty or arthrodesis can be performed.
