Abstract
The present invention generally relates to methods and devices for treatment of spinal deformity, and in particular to the utilization of at least one implant to either maintain the position of at least one vertebra of a patient to prevent increase in abnormal spinal curvature, to slow progression of abnormal curvature, or to impose at least one corrective displacement and/or rotation on at least one vertebra of a patient so as to incrementally correct abnormal spinal curvature.
Claims15
A method for treatment of spinal deformity of a patient comprising:
- providing an adjust device including:
- a housing;
- a rod having one end received in the housing and the other end extending outwardly from the housing;
- and
- a first magnet connected to the housing and configured to adjust a length of the rod;
- attaching one part of the rod to a first bone and a second part of the rod to a second bone, wherein the first bone is a pelvic bone and the second bone is a vertebra;
- positioning an actuator above a skin of the patient, the actuator having a second magnet;
- while the actuator is positioned above the patient skin, producing a magnetic field with the second magnet that interacts with the first magnet to cause the rod to extend out from the housing;
- and
- wherein the step of producing a magnetic field with the second magnet causes rotation of the first magnet which causes rotation of a leadscrew within the housing, whereby rotation of the leadscrew causes translation of the rod thereby changing a length of an exposed portion of the rod.

A method for treatment of spinal deformity of a patient comprising:
- providing an adjust device including:
- a housing;
- a rod having one end received in the housing and the other end extending outwardly from the housing, the rod having a first length;
- a lead screw coupled to the rod;
- and
- a first magnet attached to the housing;
- wherein the adjustment device is insertable into the patient;
- attaching the adjustment device to a first bone and a second bone for treating spinal deformity, wherein the first bone is a pelvic bone and the second bone is a vertebra;
- positioning an actuator above a skin of the patient, the actuator having a second magnet;
- while the actuator is positioned above the patient skin, creating a changing magnetic field by the second magnet which rotates the first magnet, whereby rotation of the first magnet causes rotation of the lead screw, whereby rotation of the lead screw causes translation of the rod such that the adjustment device changes from the first length to a second length longer than the first length.
