Hand Anatomy and Function Bone and Spine
There is a great deal of physiologic variation between individuals in the morphology of the hand bones. One tool used to discuss the variance in hand anatomy is the digit length ratio of the second to the fourth digit, otherwise referred to as the 2D to 4D ratio. This number has been demonstrated to be 0.98 among the general population but.
