1. A method of stabilizing a spine with an abnormal curvature in a subject in need thereof, the method comprising implanting one or more magnetic screw devices into each of two or more vertebrae at the abnormal curvature, adjacent to the abnormal curvature, or a combination thereof, wherein each magnetic screw device comprises a fastening stem, a housing, a magnet assembly, and one or more magnets, wherein
the fastening stem comprises a first end, a second end, a shank therebetween, and a longitudinal axis therebetween, wherein the first end comprises a spherical or part spherical surface, the second end comprises a taper to a pointed or approximately pointed shape, and the shank comprises a thread;
the housing comprises a top end, a bottom end, wall therebetween, and a bore between the top end and bottom end that defines an inner surface, wherein a portion of the inner surface adjacent to the bottom end comprises a concave spherical or part-spherical surface that is configured to engage with the spherical or part-spherical surface of the first end of the fastening stem; and wherein the housing comprises a first slot and a second slot that extends from the top end towards the bottom end and is located on opposing sites of the wall;
the magnet assembly comprises a shaft, a magnet holder on one or both ends of the shaft, a removable holder cap for each magnet holder, a longitudinal axis extending between the ends of the shaft, and a sleeve adjacent to each end of the shaft, wherein each magnet holder comprises an outer surface, a bore defining an inner surface, a closed end, and an open end; wherein each holder cap is configured to enclose the open end of the magnet holder; wherein the shaft is removably received by the first slot and second slot of the housing; and wherein the shaft is configured to extend between the first slot and the second slot of the housing; and
each magnet is configured to be received by one of the magnet holders.
