Instrumentation and methods for reducing spinal deformities

摘要

Instrumentation and methods for reduction of a spinal deformity, including a plurality of elongate alignment elements and first and second reduction elements engaged to the alignment elements. Each of the alignment elements extends generally along a longitudinal axis and includes a proximal portion adapted for coupling to a corresponding vertebra and a distal portion. The first reduction element extends along a first transverse axis and is engaged with the distal portions of the alignment elements to maintain the distal portions in general alignment along the first transverse axis. The second reduction element extends along a second transverse axis and is movably engaged with the alignment elements wherein the proximal portions are positioned in general alignment along the second transverse axis as the second reduction element is displaced in a proximal direction to thereby reduce the spinal deformity.
