The invention provides a magnesium-based screw with partial threads, the magnesium-based screw with partial threads comprises a first threaded section, a connecting section and a second threaded section, the first threaded section, the connecting section and the second threaded section are sequentially connected in a first direction, the outer diameter of the connecting section is larger than the small diameter of the threads of the first threaded section, and the outer diameter of the connecting section is larger than the small diameter of the threads of the second threaded section. And the outer diameter of the connecting section is smaller than the thread major diameter of the second thread section. According to the magnesium-based screw with the partial threads, the outer diameter of the connecting section is larger than the small diameter of the threads of the first thread section and smaller than the large diameter of the threads of the second thread section, so that the situation that stress concentrat
