Bone and joint syphilis

Syphilis is a sexually transmitted disease left over from the old society, and it has been renewed in recent years. Bone and joint syphilis is a manifestation of systemic syphilis infection in bones and joints. Due to the different time and route of infection, syphilis is divided into congenital and acquired. Congenital syphilis is caused by Treponema pallidum in pregnant women due to treponema pallidum invading the placenta and invading the fetus through the umbilical vein. Such syphilis can produce bone and joint lesions early. Acquired syphilis is caused by Treponema pallidum in contact with the skin or mucous membranes and invades from cracks and breaks. It causes bone changes in the second and third stages.
