fusion, does it always involve disc replacement

The above topic is only question. Thank!

  • Hi Binderea,
    Fusion involves joining vertebrae together which involves removing the disk entirely rather than replacing it.

  • They can do an outerbody fusion. The discs are left in place to maintain height but the lamina are fused together (bridge) to prevent movement.

  • sorry, I didn't know that
    microdiscectomy 7-2014
  • A bit over a year ago, I had a double lumbar fusion. L4-L5 got the full diskectomy and fusion cage insertion, but L5-S1 was too far gone with heteroptic ossification that the surgeon couldn't distract the space. They ended up doing a foraminotomy at that level and bolted all three vertebrae with the usual sort of hardware.
