Abstract: Inflammatory arthropathy is a group of diseases characterized by arthritis,  mainly  including rheumatoid arthritis,  spondyloarthritis and osteoarthritis.Osteoporosis is divided into primary and secondary types. Inflammatory arthropathy is a common cause of secondary osteoporosis.The incidence of osteoporosis and the risk of falls increase in inflammatory arthropathy. Therefore,  once osteoporosis appears,  the risk of fracture will increase significantly.Bone mineral density should be screened as soon as possible in patients with inflammatory arthropathy.Once osteoporosis is diagnosed,  treatment should be initiated to reduce the risk of fracture and improve the prognosis. The epidemiology and pathogenesis of inflammatory arthropathy and osteoporosis and their diagnosis as well as treatment were reviewed in this paper.

Key words: arthritis, , rheumatoid, spondylitis, osteoarthritis, osteopo
