Periodontal Ehlers-Danlos syndrome Periodontal EDS (pEDS) causes dental problems, particularly inflamed or absent gums and poor tooth development, on top of typical features of cEDS. It is rare but can be inherited from one parent only, as only one faulty gene is needed to develop the condition.
Ribs 1, 2, 11 and 12 can be describes as âatypicalâ â they have features that are not common to all the ribs. Rib 1 is shorter and wider than the other ribs. It only has one facet on its head for articulation with its corresponding vertebrae (there isnât a thoracic vertebrae above it).
Fractures of the first and second ribs are rare but may be associated with serious damage to the brachial plexus of nerves, the subclavian vessels or associated with head, facial or thoracic aorta injuries. A lower rib fracture is more likely associated with injuries to the diaphragm, liver or spleen. The most common mechanism causing rib fractures is blunt trauma (i.e. automobile accidents, falls from height, assault, or even severe coughing).
