I have ehlers danlos syndrome, i feel my hip pop out and see a bulge on the anterior side when it does. is this a subluxation?

Loose joints: While patients with Ehlers Danlos syndrome tend to have loose joints, dislocating or subluxating the hip to a noticeable degree is very unlikely. The hip is a deep ball and socket joint that is highly contained and is surrounded by thick muscles. What you are feeling "pop out" anterioy is the psoas (hip flexor) tendon that is positioned over the front of the hip joint itself
