Abstract:
1. A method of correcting a deformity of a spine in a patient in need thereof, comprising: a pre-operative stage and an operative stage; wherein said pre-operative stage comprises the steps of: analyzing an initial position of one or more vertebrae of said deformed spine; determining a pre-planned final position of said one or more vertebrae; and determining placement positions of one or more vertebral correcting elements based on said pre-planned final position of said one or more vertebrae; and wherein said operative stage comprises the steps of: surgically exposing said spine; inserting and affixing at least one set of vertebral fixing elements to said one or more vertebrae; placing one or more vertebral connector elements, wherein said one or more vertebral connector elements join individual vertebral fixing elements of said set of vertebral fixing elements; placing said one or more vertebral correcting elements, wherein said one or more vertebral correcting elements comprise polyaxial correcting elements sagittal positioning correction elements, sagittal inclination correction elements, and frontal inclination correction elements; wherein said polyaxial correcting elements are attached and fixed to a distal end of said vertebral connector elements or to said vertebral fixing elements; wherein said sagittal positioning correction elements are attached to said polyaxial correcting elements at a pre-planned distance from a distal end of said polyaxial correcting elements; wherein said sagittal inclination correction elements are attached to said polyaxial correcting elements at a pre-planned distance from said distal end of said polyaxial correcting elements; wherein said frontal inclination correction elements are attached to said polyaxial correcting elements at a pre-planned distance from said distal end of said polyaxial correcting elements; placing and tightening one or more corrective force elements, wherein said one or more correcting force elements act upon at least one of said polyaxial correcting elements, said sagittal positioning correction elements, said sagittal inclination correction elements, or said frontal inclination correction elements; placing and tightening of one or more longitudinal spinal fixing elements to said vertebral fixing elements or one or more said vertebral connector elements; removing said one or more corrective force elements; and removing said one or more polyaxial correcting elements, sagittal positioning correction elements, sagittal inclination correction elements and frontal inclination correction elements.
