Spinal Fusion: Posterior Lumbar

The bone graft is packed between the transverse processes (“wings”) on the sides of the vertebrae. This procedure is called posterolateral fusion.

To help keep your spine steady and promote fusion, extra support may be used such as titanium screws and rods. Sometimes, bone cement is added around the screws.

A wound drain is often placed in the wound and left in for a few days.

The incision is closed with stitches (sutures) or staples.

An incision is made in the middle of or on each side of your spine.

The disk between the vertebrae is removed. This procedure is known as posterior lumbar interbody fusion (PLIF).

A bone graft, a spacer (cage), or both are placed in the now-empty disk space between the vertebrae. In time, the graft or spacer and the bone will grow into a solid unit.

To help keep your spine steady and promote fusion, metal screws, and rods may be placed to provide extra support and promote healing. Sometimes, bone cement is added around the screws.

A wound drain is often placed in the wound and left in for a few days.

The incision is then closed with stitches or staples.
