1. A method of treating a spinal deformity comprising: attaching a first fastener to a first vertebral member, the first fastener including a first anchor, a first receptacle, and a first connection that movably connects the first receptacle to the first anchor for the first receptacle to move relative to the first anchor within a first range of motion; attaching a second fastener to a second vertebral member, the second fastener including a second anchor, a second receptacle, and a second connection that movably connects the second receptacle to the second anchor for the second receptacle to move relative to the second anchor within a second range of motion, the second range of motion being smaller than the first range of motion, the second connection being different than the first connection; positioning an elongated member within the receptacles of the first and second fasteners, the elongated member including a first section with a first structural characteristic and stiffness that extends through the first receptacle and along the first vertebral member and a second section with a different structural characteristic and different stiffness that extends through the second receptacle and along the second vertebral member; during growth of the vertebral members, causing the first fastener to limit movement of the first vertebral member from growing and applying a first corrective force to the first vertebral member and causing the second fastener to limit movement of the second vertebral member from growing and applying a second corrective force to the second vertebral member, the second corrective force being different than the first corrective force.
