Abstract
A magnetic screw device of a bone screw and one or more magnets that are attached to the bone screw. The bone screw may have a stem, which comprises a connector and at least one thread, and a housing assembly. The connector of the stem may be configured to articulate with the housing assembly such that the stem can rotate and angulate relative to the housing assembly. The magnetic screw device may be used to treat or stabilize spines with abnormal curvature, prevent further curvature progression, and relieve pain associated with abnormal curvature.
Claims19
A method of treating a spine with an abnormal curvature in a subject in need thereof, the method comprising
- (a) implanting one or more magnetic screw devices into two or more vertebrae at the curvature, and
- (b) orienting the magnetic screw devices to align their magnetic poles,
- therefore treating the spine with the abnormal curvature;
- wherein each magnetic screw device comprises a bone screw and one or more magnets attached thereto,
- wherein the bone screw comprises a stem and a housing assembly, the stem comprising a connector and at least one thread, wherein the connector of the stem is configured to articulate with the housing assembly such that the stem can rotate and angulate relative to the housing assembly;
- wherein the housing assembly further comprises a locking mechanism configured to lock the housing assembly at a set rotation and angulation relative to the stem;
- and
- wherein the one or more magnets are attached to the housing assembly of the bone screw, and are not between the locking mechanism and the connector.
