Real-time cine magneticresonance imaging of the human metacarpalphalangeal joint undergoing traction.

Note that the joint surfaces stay in close contact. Then, as traction forces increase, a focal area of increased signal intensity is visualized prior to the critical point where rapid joint separation occurs and cavity formation is then visualized.
