Back pain and spinal surgery: log rolling, neurological checks of the legs and teaching

  • Safe practice

After spine surgery the nurse compares leg power and feeling with the baseline, watches bladder and bowel and teaches what to avoid at home.

What it is

Most back pain gets better with time and staying active, and bed rest is not recommended. A few warning signs (loss of bladder or bowel control, numbness of the buttocks or legs, leg weakness, fever with back pain) need urgent assessment because nerve damage can become permanent. After spine surgery (removal of a disc, widening of a nerve opening, fusion) the key nursing task is the neurological check of the limbs: motor power, feeling, and bladder and bowel function, compared with the pre-operative baseline. A study of spinal nursing found that staff often called power "normal" if the limb moved at all, and that a post-operative haematoma was slow to be recognised. A clear check, a clear record and a clear escalation path are the safeguards.

What it requires

  • Bed rest is not recommended for acute back pain; activity is reduced only for a couple of days and then increased gradually.
  • A spinal motor assessment grades power in each muscle group of the arms (C5–T1) and legs (L2–S1) on a standard scale, plus light-touch sensation and bladder and bowel function.
  • After discharge: sit for short periods, walk short distances and increase gradually, bend the knees to pick things up, no heavy loads, no smoking (it slows healing, more so after fusion).
  • Fusion bones need at least 3–4 months to heal well.

How it is applied (and why)

  1. Record the baseline power, sensation and bladder and bowel function before surgery: change can only be seen against it.
  2. After surgery, check power of each muscle group, sensation and the groin area at the ordered interval: a growing haematoma compresses nerves.
  3. Record power with the standard grades, not "moves": small losses are the first sign.
  4. Check the wound and drain for bleeding or discharge, and the calves for swelling.
  5. Ask about passing urine and check for retention as per protocol: bladder and bowel changes are part of the neuro check and are often missed.
  6. Move the patient as ordered (log roll if ordered, brace if prescribed) and help with the first walk: it prevents falls and strain.
  7. Give pain relief before activity as prescribed and assess its effect: pain blocks early walking.
  8. Teach: no bending at the waist or twisting, no heavy lifting, short sitting periods, wound checks, no smoking, when to call.

In nursing practice

  • Call at once: new or worsening weakness, numbness or change in feeling in the legs (or arms after neck surgery), new trouble passing urine or controlling the bowel.
  • Report: increasing pain at the site, wound drainage (especially green or yellow), redness, warmth or opening, fever of 38.3 °C or higher, chills.
  • Report: calf swelling or pain, chest pain or shortness of breath (possible clot); severe headache that does not ease.
  • Healing after disc surgery is usually quick; after laminectomy and fusion it takes longer.

Common mistakes

  • Writing "moves all limbs" instead of grading the power of each muscle group.
  • Not checking bladder and bowel function and groin sensation in the neuro check.
  • Waiting for the next scheduled check, or for the morning, to report new leg weakness.
  • Telling a patient with acute back pain to stay in bed.

Test yourself

Think of the answer, then tap the question to see it.

Why is "the patient moves the legs" not enough after spine surgery?

Power must be graded for each muscle group and compared with the baseline. A small loss of power can be the first sign of a haematoma pressing on the nerves.

Which changes after spine surgery need an immediate call?

New or worsening weakness or numbness in the legs (or arms after neck surgery), and new difficulty passing urine or controlling the bowel.

Is bed rest recommended for acute low back pain?

No. Activity is reduced for only a couple of days and then increased gradually; heavy lifting and twisting are avoided at first.

Which three back-pain red flags need urgent assessment?

Loss of bladder or bowel control, numbness of the buttocks or legs, leg weakness; also fever with back pain, pain after a fall and a history of cancer.
