It is common for patients to experience discomfort and pain following spinal fusion surgery as their body readjusts. However, if pain starts to be a problem for the patient, then it could be symptomatic of a serious issue.

Early onset of pain

If there are pain symptoms in the weeks following spinal fusion surgery there are several possible causes:

  • Infection
  • Misplaced screws causing nerve pain
  • Early failure of fixation – screws loosening
  • Failure to address the original problem – in which case the original symptoms and pain persist.

Diagnosis

  • Infection: a quick inspection of the wound may reveal an obvious problem. If still unsure, a CRP blood test can help determine if there is an infection.
  • Ask about the location of the pain. Is it purely pain in the lower back, or is it nerve pain in the legs?

If it is lower back pain it is probable that it is the body still readjusting and the patient just needs to give the body time. Nonetheless if the pain is worsening, refer them back to the operating surgeon.

If there are any nerve pain issues your patient should be referred straight back to their operating surgeon.

A simple X-Ray or CT scan will determine if there has been any dislodgment of the fixation screws or fractured vertebrae.

Note the X-Ray should be taken in the standing position and cover all parts of the back that were operated on.

If the X-Ray reveals any dislodgment then send your patient straight back to the operating surgeon. Immediately.

If the surgeon is unavailable, or the patient distrusts the operating surgeon, then they should seek a second surgical opinion.

Later onset of pain

If pain or nerve symptoms appear six months or more after surgery there are several possible causes and all of them require attention:

  • Failure of the fusion – possible breakage of the fixation hardware
  • Vertebral fracture adjacent to the fusion
  • Degenerative change of the disc space adjacent to the fusion with the potential for nerve compression
  • Loss of spinal balance due to forward angulation above the fusion.

Any of these could get out of hand; the patient needs to be sent to their operating surgeon without too much delay.

Diagnosis

Ask the patient to try and determine how much is back pain and how much is leg pain.

If leg pain and there is weakness then it is urgent, and the patient may need to go to hospital immediately.

If back pain, there still needs to be a surgical review and an X-Ray in a standing position is an important starting point in the diagnosis. But it is best to leave any further investigations to the treating surgeon.

Live webinars for referrers: CAUDA EQUINA SYNDROME

 

I will start giving a series of live webinars for referrers.

The first one will be Cauda Equina Syndrome and involve a discussion about its causes, symptoms, and diagnosis.

You’ll also have the opportunity to ask me any questions.

It will be on Wednesday 11 August 2021 from 8am to 8.30am.

Simply click here to register.

NB: a recording will be available to view at a later date if you cannot make the live webinar.
