Can you tell me what it mean if all your fingers overlap your thumb around your wrist, including your pinky?

It: May be joint hypermobility syndrome or ehlers-danlo.

Small boned: If your index finger and thumb overlap around the skinniest part of your wrist, it means that you have a relatively small skeletal frame. People who are large framed will see a gap between those fingers when they try to wrap them around the wrist. Medium framed will have the two ends of the fingers touching with no overlap or gap.
