Phalangeal adduction, abduction

The hand consists of five metacarpal bones that articulate proximally with four carpal bones in the distal row. The second and third metacarpals remain relatively fixed while the first, fourth, and fifth move around this fixed segment. The five metacarpals articulate distally with the proximal phalanges of the fingers. These are usually considered ginglymus or hinge joints. They permit flexion-extension, abduction, adduction, and circumduction. 

After the determine appropriate endoskeletal data such as length of phalange based on average Asian male hand and range of motion for flexion/extension and abduction/adduction...
