摘要:
A repair technique utilizing an elastic loop that is inserted on each side of an annular tear or annular incision following discectomy. The loop is initially an opened linear strand with the open ends inserted on each side of the annular tear with guiding arms in curvilinear fashion. The ends are joined together in the substance of the annulus where the ends are locked under tension. The insertion device is then removed and the elastic loop, which has been under tension, will tighten causing the annular tear to pull together thereby diminishing or eliminating any gap. One or more annular elastic sutures can be used for each annular tear to insure proper closure. The insertion device has guiding arms that push the open ends of the annular suture loop through the substance of the annulus and then forces them together engaging a locking mechanism inside the substance of the annulus. This technique allows for relatively easy and quick repair of the annular defect or tear.
