Abstract

An internal brace system (10) includes a pair of implantable rods (12,14) for mounting on either side of the spinal column S co-extensive with a portion of the spinal column to be treated. Transverse bars (16,18) rigidly connect the rods (12,14) together in spaced-apart parallel arrangement to provide a unitary internal brace stabilizing structure. Pairs of anchors in the form of cuffs (20a, 20b) are provided with one of each pair on respective transverse processes (P L, P R) of each selected vertebra (V) in the portion of the spinal column (S) to be treated. A flexible first tie member (22a,22b) extends from each anchor cuff (20a,20b) to a sleeve (24a,24b) on a respective rod (12,14) on either side of the spinal column S for retaining individual vertebra (V) in a predetermined location relative to the internal brace system (10) and against torsional forces applied through the spinal column S. A further anchor (78) is provided on the spinous process of the selected vertebra (V). Second flexible tie members (84) extend from the respective cuffs (20a,20b) on the transverse processes (P L, P R) to the anchor (78) on the spinous process (T) in order to prevent the cuffs (20a,20b) from slipping off the transverse processes (P L, P R).
