ICD-10: A50.55

Clinical Description of ICD-10 Code A50.55: Late Congenital Syphilitic Arthropathy

ICD-10 Code A50.55 refers to a specific condition known as late congenital syphilitic arthropathy. This condition is a manifestation of congenital syphilis, which is an infection caused by the bacterium Treponema pallidum that is transmitted from an infected mother to her fetus during pregnancy.

Overview of Congenital Syphilis

Congenital syphilis occurs when a pregnant woman with syphilis transmits the infection to her baby, potentially leading to a range of health issues. The effects can vary significantly depending on the timing of the infection during pregnancy and the treatment received. If untreated, congenital syphilis can result in severe complications, including stillbirth, neonatal death, and various long-term health problems in surviving infants.

Late Congenital Syphilitic Arthropathy

Late congenital syphilitic arthropathy specifically refers to joint and bone abnormalities that develop in children who were infected with syphilis in utero. This condition typically manifests later in childhood or adolescence, often after the initial symptoms of congenital syphilis have subsided.

Clinical Features

1. Joint Involvement: Patients may experience pain, swelling, and deformities in the joints. The most commonly affected joints include the knees, ankles, and wrists.

2. Bone Changes: Radiological examinations may reveal characteristic changes in the bones, such as osteochondritis or other developmental abnormalities.

3. Growth and Development Issues: Children with late congenital syphilitic arthropathy may exhibit delayed growth and development, which can be attributed to the underlying infection and its effects on the musculoskeletal system.

4. Other Associated Symptoms: In addition to arthropathy, affected individuals may present with other signs of congenital syphilis, such as dental abnormalities (Hutchinson's teeth), hearing loss, and skin rashes.

Diagnosis and Management

Diagnosis of late congenital syphilitic arthropathy typically involves a combination of clinical evaluation, patient history, and imaging studies. Serological tests for syphilis, such as the RPR (Rapid Plasma Reagin) or VDRL (Venereal Disease Research Laboratory) tests, may also be employed to confirm the diagnosis.

Management of this condition focuses on symptomatic relief and may include:

• Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to alleviate joint pain and inflammation.
• Physical Therapy: Rehabilitation exercises may help improve joint function and mobility.
• Surgical Intervention: In severe cases, surgical procedures may be necessary to correct deformities or relieve pain.
