摘要：
An internal fixation device is adapted for fixing a first bone fracture to a second bone fracture. The internal fixation device includes: a shank adapted to extend into the first and second bone fractures and including a connecting segment that is made of a shape-memory alloy, and a first threaded segment that is connected to a first end of the connecting segment and that is adapted to be fixed in the first bone fracture and a fixing unit adapted to fasten the second bone fracture to the first bone fracture. When environmental temperature is increased to a predetermined temperature, the connecting segment is shortened such that the fracture surfaces of the first and second bone fractures are 15 pressed closely against each other.
