DescriptionClavicle showing syphilitic periostitis.
Left clavicle from an adult with acquired syphilis, showing changes due to syphilitic periostitis.
The anterior surface for some 4 cm at the middle of the clavicle is irregularly decalcified and absorbed, while the surface in the neighbourhood is porous and in places a slight veneer of new bone has formed Subperiosteally. The inferior surface of the clavicle is not affected. There is an irregularity at the lateral extremity of the clavicle which suggests a similar affection at the acromioclavicular articulation.
