Abstract
The present invention relates to a bone fixation device having a fixation member using a shape memory effect to secure bone fractures, including but not limited to, femur, tibia and humerus fractures. The fixation member can be malleable at a room temperature, but become rigid at a body temperature because of the shape memory effect, such as derived from a super-elastic property found in such as a nickel titanium alloy. The fixation member can be formed on one or more of the shaft portion and the two end portions of a nail member for securing bone fractures, such as by providing translational and rotational stabilities. The fixation member is also capable of providing a continuous and controllable compression force over the fractured bone, if needed.
