Common causes of hypermobile joints. Most commonly, hypermobile joints appear without any underlying health conditions. This is called benign hypermobility syndrome since the only symptom is hypermobile joints. It can be caused by: bone shape or the depth of the joint sockets. muscle tone or strength.
The term double-jointed is an inaccurate way of saying that someone has hypermobility of their joints. Double-jointed would imply that the individual has more joints than normal or that their joints have a twice-normal motion â neither of these is true. The truth is that people who are called double-jointed have joints with more mobility than normal. In some individuals, this is normal. In others, there is an underlying medical reason for the joint laxity.
