Sabre shin deformity

an abnormality of the tibia characterized by marked anterior bowing of the lower leg. This defect may be seen in some children with congenital syphilis and in patients with yaws, osteitis deformans and Pagets disease. A similar deformity may occur as a manifestation of rickets caused by bowing and a strong posterior pull of the Achilles tendon on the weakened growth plate of the calcaneus.
