Biomechanical Simulation of the Effect of the Extrinsic Flexor Muscles on Finger Joint Flexion.

摘要

The mechanisms responsible for producing flexion of the metacarpophalangeal (MCP) joints of the fingers remain a matter of debate. Especially, the role of the extrinsic finger flexor muscles has been questioned. Using computer simulation techniques, we sought to determine if it is possible for the extrinsic flexor muscles to produce rotation at all three finger joints and to initiate rotation at all MCP joint.
