Symptom #8: Deformities of the Fingers
Individuals with Ehlers-Danlos syndromes tend to develop deformities in their fingers such as the swan neck deformity and boutonniere deformity. Swan neck deformity refers to the deformed position of the finger where the joint in the fingertip is flexed while the next joint towards the palm is extended.
In a boutonniere deformity the joint in the fingertip is extended while the next joint towards the palm is flexed. It is opposite of a swan neck deformity and can be seen in patients with Ehlers-Danlos syndromes. Both deformities are also seen in injury and patients with rheumatoid arthritis.
