Posterior Dynamic Stabilization with Limited Rediscectomy for Recurrent Lumbar Disc Herniation.

TDS combined with limited rediscectomy resulted in an effective procedure in middle-aged patients with Carragee type II and type IV RLDH. It was able to stabilize the operated segment with partial motion preservation. Moreover, it could maintain disc height and decrease the risk of recurrence in patients with a large posterior annular defect.
