1. A spine implant comprising: a first rod having a first end and a second end; said first rod having a platform midway between the first end and the second end; a second rod connected to the platform transverse to said first rod; said second rod adapted for supporting a load between a first vertebra and a second vertebra and transmitting said load to said platform; said first rod being configured such that the platform deflects in response to said load transmitted from said second rod; said rod platform having a first load to deflection profile in a first direction of deflection; and said rod having a second load to deflection profile in a second direction of deflection.
