A simple and flexible non-synthetic ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis. A single length of allograft or autograft is provided, per each side of the vertebral column, to replace and recreate the spinal ligament spanning adjacent vertebrae. The single length allograft or autograft is secured to spine pedicles with fixation devices such as bone screws like interference screws and/or anchors such as SwiveLock® or PushLock® anchors.
