Abstract:
1. A method of treating a spinal deformity comprising: attaching a first fastener to a first vertebral member that is offset a first amount from a correct alignment of the first vertebral member in a coronal plane, the first fastener being of a first type with a first anchor having first head and a saddle having a first receptacle pivotally and rotatably connected with the first head to allow a first range of motion between the first receptacle and the first anchor through multiple planes; attaching a second fastener to a second vertebral member that is offset a second amount from a correct alignment of the second vertebral member in the coronal plane that is less than the first amount, the second fastener being of a different second type with a second anchor having a second head and a saddle having a second receptacle rotatably mounted on the second head to allow a second range of motion between the second receptacle and the second anchor through a single plane, the second anchor including a wall that forms a barrier between the second receptacle and a distal cavity, the second head being rotatably positioned in the cavity; attaching a third fastener to a third vertebral member that is offset a third amount from a correct alignment of the third vertebral member in the coronal plane that is less than the second amount, the third fastener being of a different third type with a third anchor having a third head and a saddle having a third receptacle mounted on the third head to prevent movement between the third anchor; and positioning an elongated member within the receptacles of the first, second, and third fasteners and limiting growth on a convex side of the first, second, and third vertebral members; the first, second, and third fasteners limiting motion of the first, second, and third vertebral members and reducing the spinal deformity during the growth of the vertebral members.
