I have always been fascinated when people can bend their fingers backwards. Most people call this being double-jointed, but actually there is only one joint but the ligaments are stretched so their length of movement is extended. As we have been learning about the skeletal system in science class, we learned that a joint is where two bones meet, and ligaments connect the two bones together in a joint. Ligaments are a short band of tough, flexible connective tissue. The technical term for double-jointed is hypermobility. You can have one or two hyper mobile joints or a large group of them. In most cases it won't involve any treatment but sometimes, if the ligaments around a joint are too loose, it can cause joint pain and increase the risk of dislocating that joint. Hypermobility can be caused by age, genes, or even repetitive stretching. If you want to learn more go here,
