Saber shin is a malformation of the tibia characterized by a sharp anterior bowing, or convexity, of the tibia, resembling the curve of a saber. It is a sign of congenital syphilis and is caused by periostitis.

Causes[edit]

The primary cause of saber shin is congenital syphilis. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. When a pregnant woman has syphilis, the infection can be transmitted to the fetus, leading to congenital syphilis. Other causes may include Paget's disease and rickets.

Symptoms[edit]

The main symptom of saber shin is the abnormal curvature of the tibia. This can lead to difficulty walking and pain in the legs. Other symptoms may include joint pain, fatigue, and fever.

Diagnosis[edit]

Diagnosis of saber shin is primarily based on physical examination. The doctor may also order blood tests to confirm the presence of syphilis or other underlying conditions.

Treatment[edit]

Treatment for saber shin involves treating the underlying cause. This may include antibiotics for syphilis or other treatments for conditions like Paget's disease or rickets. In severe cases, surgery may be required to correct the deformity.
