An internal brace system includes a pair of implantable rods for mounting on either side of the spinal column co-extensive with a portion of the spinal column to be treated. Transverse bars rigidly connect the rods together in spaced-apart parallel arrangement to provide a unitary internal brace stabilizing structure. Pairs of anchors in the form of cuffs are provided with one of each pair on respective transverse processes of each selected vertebra in the portion of the spinal column to be treated. A flexible first tie member extends from each anchor cuff to a sleeve on a respective rod on either side of the spinal column for retaining individual vertebra in a predetermined location relative to the internal brace system and against torsional forces applied through the spinal column. A further anchor is provided on the spinous process of the selected vertebra. Second flexible tie members extend from the respective cuffs on the transverse processes to the anchor on the spinous process in order to prevent the cuffs from slipping off the transverse processes.
