Polylactic acid (PLA) is a bioabsorbable polymer that is used in a variety of medical conditions. Complex forms of this material are commonly made ​​for fixation and reconstruction of bone fractures. These bioabsorbable implants have been gaining popularity as an alternative to metal implants to stabilize small fractures due to its metal counterpart, avoiding problems such as bone resorption, additional surgery after fixation, infection and possible new fractures. In this paper are shows a number of finite element analysis that aims to determine the functionality of the plates and screws fixation with bioabsorbable material made ​​from PDLLA copolymers 50/50 and 85/15 PLLA-PGA respectively, for fixing and rebuilding of bone fractures in hand.
