Pseudarthrosis or Nonunion due to failed or previous lumbar surgery. The poor healing of bone in the spine region is usually due to the failure of lumbar surgery (e.g. lumbar fusion) that leads to the formation of a nonunion. Usually, post-surgery, damaged lumbar bones heal by forming new bone tissue between the spinal bones. However, if the lumbar bone fails to heal, then it results in formation of a nonunion or pseudarthrosis.
