Secondary syphilitic osteopathy
ICD-10 A51.46 is a billable code used to indicate a diagnosis of secondary syphilitic osteopathy.
Secondary syphilitic osteopathy is a manifestation of secondary syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. This condition typically arises after the initial primary stage of syphilis, characterized by the appearance of a painless ulcer known as a chancre. In the secondary stage, systemic dissemination of the bacteria occurs, leading to a variety of symptoms, including skin rashes, mucous membrane lesions, and lymphadenopathy. Osteopathy, or bone disease, can occur as a result of the inflammatory response to the infection, leading to bone pain, swelling, and potential deformities. Diagnosis is primarily clinical, supported by serological tests such as the rapid plasma reagin (RPR) and treponemal tests. Treatment involves the administration of antibiotics, typically benzathine penicillin G, which is effective in eradicating the infection and preventing further complications. Early detection and treatment are crucial to prevent long-term sequelae, including tertiary syphilis, which can lead to more severe systemic involvement.
