Spinal Surgery Nursing Guide

Common Spinal Procedures

Surgical Procedures — Overview

Discectomy

Removal of herniated disc material compressing the nerve root or spinal cord. Most commonly performed at L4/L5 or L5/S1 levels. Minimally invasive (microdiscectomy) or open approach. Aims to relieve radicular pain and neurological deficit.

Laminectomy (Spinal Decompression)

Removal of the lamina (bony arch of the vertebra) to decompress the spinal canal in spinal stenosis. Often combined with discectomy. Results in reduced stability — may be combined with fusion.

Spinal Fusion (PLIF / TLIF / ALIF / XLIF)

Fusion of adjacent vertebrae using bone graft ± instrumentation (pedicle screws, rods, cages). PLIF = Posterior Lumbar Interbody Fusion; TLIF = Transforaminal; ALIF = Anterior; XLIF = Extreme Lateral. Aims to restore alignment and eliminate painful motion segment.

Vertebroplasty / Kyphoplasty

Minimally invasive injection of bone cement (PMMA) into a vertebral compression fracture. Kyphoplasty first inflates a balloon to restore vertebral height. Used for osteoporotic fractures, metastatic disease. Performed under fluoroscopy.

Motor Power Grading Scale

MRC (Medical Research Council) Muscle Power Grades 0–5

Grade 0: No muscle contraction visible or palpable. Complete paralysis.

Grade 1: Trace contraction visible but no joint movement.

Grade 2: Active movement possible but NOT against gravity (movement in horizontal plane only).

Grade 3: Active movement against gravity but NOT against resistance.

Grade 4: Active movement against gravity AND some resistance. Slightly reduced power.

Grade 5: Normal muscle power. Full strength against full resistance.

Document baseline before surgery and reassess each limb every 1–2 hours post-operatively. Any NEW deficit from baseline requires URGENT surgical review.

Pre-Operative Assessment

Baseline Neurological Assessment

A thorough baseline neurological assessment is essential before spinal surgery. Post-operative changes can only be correctly interpreted if the pre-operative baseline is documented.

Motor power: Grade 0–5 in all four limbs; specific myotome testing (hip flexors L2, knee extensors L3, ankle dorsiflexors L4, extensor hallucis longus L5, ankle plantarflexors S1)
Sensation: Light touch, pinprick, proprioception in all dermatomes
Reflexes: Knee jerk (L3/L4), ankle jerk (S1), plantar response (upper motor neuron signs)
Bladder and bowel function: Any urinary retention, incontinence, or faecal incontinence — critical baseline for detecting cauda equina syndrome
Pain: Document location, character, radiation pattern, and VAS score

Saddle anaesthesia check: Before cervical or lumbar surgery, document perineal sensation ("saddle area" — inner thighs, perineum, perianal). Loss of saddle sensation post-operatively = cauda equina syndrome until proven otherwise.

Pre-Operative Optimisation

Factor	Action	Rationale
Smoking	Cessation ≥4 weeks pre-op	Smoking impairs bone fusion and wound healing; nicotine inhibits osteoblast function
Anaemia	Hb correction; IV iron if Hb <10 g/dL	Spinal surgery carries blood loss risk; low Hb increases transfusion requirement and wound healing impairment
Anticoagulation	LMWH bridge per protocol; warfarin held 5 days pre-op; DOACs held 24–48h	Epidural haematoma risk if anticoagulated at time of spinal surgery
Diabetes	HbA1c <8% target; insulin sliding scale peri-op	Hyperglycaemia impairs healing and increases infection risk
Spinal cord monitoring	SSEP/MEP (somatosensory/motor evoked potentials) in complex multi-level surgery	Real-time monitoring during surgery — alerts surgeon to cord injury before irreversible damage

Post-Operative Neurology Monitoring

Monitoring Protocol — First 24 Hours

Neurological observations every 30 minutes for 2 hours, then every 1 hour for 6 hours, then every 2 hours if stable
Each observation: motor power both lower limbs (hips, knees, ankles, toes), sensation light touch, complaint of new weakness/numbness/pain
Compare EVERY reading to the documented PRE-OPERATIVE BASELINE
Urinary output: hourly for first 12 hours; urinary retention post-spinal anaesthesia vs new neurological deficit needs differentiation
Wound assessment: inspect every 4 hours; haematoma (rapidly expanding swelling) = EMERGENCY

New neurological deficit post-spinal surgery = SURGICAL EMERGENCY until proven otherwise. Any new motor weakness, sensory loss, or bladder/bowel change compared to pre-operative baseline must be reported to the surgical team IMMEDIATELY — may indicate spinal cord or nerve root compression from haematoma, bone fragment, or cord oedema requiring urgent return to theatre.

Positioning — Log Roll Technique

Log Roll

The log roll is the mandatory technique for repositioning all post-spinal surgery patients. It maintains spinal alignment and prevents torsional forces on the operative site, implants, and healing bone.

Minimum 3 persons required (1 at head/neck, 1 at torso/hips, 1 at legs); 4 persons for complex cervical cases
One designated leader at the head coordinates all movements with a count ("Ready — 2 — 3 — roll")
All personnel move the patient as a rigid unit simultaneously — NO twisting, bending, or flexion of spine
Use a draw sheet or transfer board to reduce friction
Reposition every 2 hours — pressure injury prevention; document position in nursing notes
Place pillows between knees when side-lying to maintain neutral hip/lumbar alignment

The 3Bs — Post-Spinal Surgery Restrictions

No BENDING

No TWISTING

No heavy LIFTING

These three movements apply excessive forces to the operative site and can displace instrumentation, disrupt fusion, or reinjure the disc/nerve.

Drain Management

Spinal/epidural drains may be placed to prevent haematoma formation in the epidural space
Measure drain output hourly for first 12 hours, then 2-hourly
Concern: >150 mL/hour drainage — notify surgical team (risk of haematoma, CSF leak)
Check drainage colour: serosanguinous (expected) vs bright red (active haemorrhage) vs clear/watery (possible CSF leak)
Do NOT clamp drain unless specifically instructed by surgeon — clamping risks haematoma accumulation
Maintain drain below wound level at all times to allow passive drainage by gravity
Document cumulative output at each assessment; inform surgeon when total output exceeds 400 mL

VTE Prophylaxis & Early Mobilisation

Spinal surgery patients are at HIGH VTE risk — immobility + surgical trauma + pelvic venous stasis
LMWH (e.g., enoxaparin 40 mg SC once daily) usually commenced 24–48 hours post-op once haemostasis confirmed
TED (Thrombo-Embolus Deterrent) stockings: apply before surgery and maintain until fully ambulant
Pneumatic compression devices (sequential compression): applied intra-operatively and maintained post-op when not ambulant
Early mobilisation: Most patients are sat up day 0 or 1; walking with physiotherapist support typically day 1 post-op
Return-to-activity milestones: driving 4–6 weeks; no heavy lifting for 12 weeks; physiotherapy for core strengthening mandatory for all fusion patients

Post-Operative Complications

Post-Dural Puncture Headache (PDPH)

PDPH occurs when the dura is inadvertently punctured during surgery, allowing CSF to leak. Classic presentation: severe positional headache that is WORSE sitting/standing and BETTER lying flat ("orthostatic headache").

Typically occipital/frontal; may be associated with nausea, neck stiffness, visual/hearing changes
Conservative management (first 24–48h): Bed rest supine, oral hydration, caffeine (stimulates CSF production — 300mg caffeine PO/IV), paracetamol/NSAIDs, stool softeners (avoid Valsalva)
Blood patch: 15–20 mL autologous blood injected into epidural space at puncture site — highly effective (90%+ success rate); used if conservative measures fail after 24–48h

CSF leak vs PDPH: Clear watery discharge from wound + persistent positional headache = suspect CSF leak. Test drainage with glucose oxidase strip (CSF contains glucose; serous exudate does not). If positive, urgent neurosurgical review — may require surgical dural repair.

Cauda Equina Syndrome — SURGICAL EMERGENCY

Cauda equina syndrome (CES) results from compression of the cauda equina nerve roots (L2–S5) below the level of the conus medullaris. It is a true surgical emergency — delay leads to permanent neurological deficit.

Classic triad of cauda equina syndrome:
1. Saddle anaesthesia (numbness/tingling in perineum, genitals, inner thighs, buttocks — the "saddle area")
2. Urinary retention or incontinence (bladder dysfunction)
3. Bilateral lower limb weakness

Any patient developing CES features post-spinal surgery must have the surgical team notified IMMEDIATELY
MRI spine is the investigation of choice — confirms level and degree of compression
Decompressive surgery (emergency return to theatre) within 24–48 hours improves prognosis — the sooner the better
Nursing: document exact time of symptom onset; urinary catheter (retention); monitor lower limb power/sensation hourly

Wound Haematoma

Spinal wound haematoma = EMERGENCY. Haematoma in the epidural space compresses the spinal cord or cauda equina. Signs: rapidly increasing localised wound swelling, worsening pain, new neurological deficit. Call surgical team immediately — requires urgent return to theatre for haematoma evacuation.

Other Complications

Complication	Signs/Symptoms	Action
Wound infection	Redness, warmth, discharge, fever >38.5°C >72h post-op	Wound swab; IV antibiotics; surgical review
Implant failure	New back pain, neurological change	X-ray/CT; neurosurgical review
Failed fusion	Persistent pain at 6–12 months; confirmed on imaging	CT to assess fusion; revision surgery if symptomatic
Adjacent segment disease	New symptoms above/below fusion level	MRI; conservative vs surgical management
DVT / PE	Calf pain, swelling, dyspnoea, pleuritic chest pain	Doppler USS legs; CT-PA; therapeutic anticoagulation

GCC-Specific Spinal Surgery Context

High Prevalence of Lumbar Disc Disease in GCC

The GCC has an exceptionally high burden of lumbar disc disease and spinal pathology, driven by the region's large manual labour workforce and prevalent sedentary lifestyle diseases.

Manual labour workforce: Saudi Arabia, UAE, Qatar and Kuwait employ millions of construction and domestic workers who perform heavy repetitive lifting — primary risk factor for disc herniation and lumbar spondylosis
Obesity and diabetes: High T2DM and obesity prevalence in GCC nationals increases degenerative spine disease; disc degeneration accelerated by metabolic factors
Sedentary working population: Office/administrative workers in GCC at high risk of lumbar disc disease from prolonged sitting and low core muscle activity
UAE and Saudi Arabia have invested significantly in spinal neurosurgery infrastructure — Spine Centres of Excellence at Cleveland Clinic Abu Dhabi, King Fahad Medical City Riyadh, etc.

Labour Injury Compensation Pathway for Expat Spinal Injuries ▼

Construction workers who sustain spinal injuries (fall from height, crush, vehicle accident) are entitled to compensation under GCC Workmen's Compensation legislation
UAE: Federal Law No. 8/1980 (Labour Law) + MOHRE-registered occupational insurance; Qatar: Worker's Support and Insurance Scheme; Saudi: GOSI (General Organisation for Social Insurance)
Nurses in spinal units should be aware that low-income expat workers may face barriers to accessing post-surgical rehabilitation due to financial constraints — hospital social work referral is important
Documentation of mechanism of injury, employment status, and employer details is important for compensation claim process — nurses can facilitate by ensuring records are complete

DHA/DOH Spinal Surgery Guidelines ▼

Dubai Health Authority (DHA) and Department of Health (DOH) Abu Dhabi have established clinical pathways for elective spinal surgery including pre-operative physiotherapy trials (mandatory 6-week conservative management before elective discectomy in most cases)
Enhanced Recovery After Surgery (ERAS) protocols for spinal surgery are increasingly adopted in GCC tertiary centres — early mobilisation day 0–1, multimodal analgesia (avoid opioids as sole analgesia), early nutrition
HAAD/DOH standards require documented neurovascular assessment charts for all spinal surgery patients — nurses must complete these at defined intervals

Post-Surgical Rehabilitation Access in GCC ▼

Rehabilitation access after spinal surgery is highly variable — GCC nationals and insured expats typically have access to physiotherapy and rehabilitation; low-income migrant workers may not
Physiotherapy is essential for core strengthening after lumbar fusion — failure to complete rehabilitation significantly increases risk of re-injury and poor functional outcome
Discharge planning should include physiotherapy referral, written instructions on 3Bs, lifting restrictions, and driving restrictions — communicated in patient's own language
Telehealth physiotherapy services expanding in GCC — useful for patients in remote areas or with transport limitations

Exam MCQs — DHA / DOH / SCFHS / QCHP

Q1. You are caring for a 45-year-old man who underwent L4/L5 discectomy 6 hours ago. He was mobile and continent pre-operatively (baseline motor power 5/5 bilaterally). During your neurological assessment, you find new onset bilateral lower limb weakness (grade 3/5), inability to void urine (400 mL retained), and the patient reports numbness in the perineal and inner thigh area. What is the PRIORITY nursing action?

A) Encourage the patient to walk to the bathroom — urinary retention is common post-spinal anaesthesia and will resolve B) Insert urinary catheter and document the finding — review in 2 hours if no improvement C) Immediately notify the surgical team — this presentation (saddle anaesthesia + urinary retention + bilateral leg weakness) is cauda equina syndrome requiring emergency evaluation and possible return to theatre D) Administer prescribed analgesia — the symptoms are likely pain-related and will improve with pain control

The correct answer is C. The triad of saddle anaesthesia (perineal/inner thigh numbness) + urinary retention + bilateral lower limb weakness = cauda equina syndrome. This is a SURGICAL EMERGENCY. Time to decompression is critical — delay beyond 48 hours significantly worsens neurological outcome, and permanent bladder/bowel/sexual dysfunction may result. The surgical team must be notified IMMEDIATELY. Urinary catheterisation will also be needed, but the priority action is immediate notification — not waiting to see if symptoms resolve.

Q2. A 52-year-old woman underwent L3/L4 laminectomy and fusion with pedicle screws yesterday. She complains of a severe headache that is much worse when she sits up or stands, and completely resolves when she lies flat. She is afebrile, has no neck stiffness, and neurological examination is unchanged from baseline. What is the MOST likely diagnosis and initial management?

A) Meningitis — fever absent but still possible; start IV antibiotics and lumbar puncture B) Post-dural puncture headache — manage with bed rest, oral caffeine (300mg), adequate hydration, and analgesia; blood patch if no improvement after 24–48 hours C) Epidural haematoma — urgent CT scan and surgical review D) Postoperative hypertension — check blood pressure and administer antihypertensive

The correct answer is B. The CLASSIC feature of post-dural puncture headache (PDPH) is the POSTURAL nature — dramatically worse upright (sitting/standing) and relieved by lying flat. This is pathognomonic for PDPH and distinguishes it from other post-operative headaches. It occurs when the dura is inadvertently punctured during surgery, causing CSF leak and reduced CSF pressure. Initial management: strict bed rest (supine), caffeine (oral or IV — stimulates CSF production), analgesia, and IV/oral hydration. If no improvement after 24–48 hours, an epidural blood patch (injection of 15–20 mL autologous blood into the epidural space at the puncture site) is highly effective.

Q3. You are repositioning a patient who underwent L5/S1 PLIF (posterior lumbar interbody fusion) 18 hours ago. The patient is being turned from supine to right lateral position. Which technique is CORRECT?

A) The patient may pivot their own body by twisting their torso — independent mobilisation is encouraged to reduce nursing workload B) Two nurses are sufficient — one at the shoulders and one at the hips; each moves their section simultaneously C) Log roll with a minimum of 3 persons — one coordinating at the head, others at torso and legs; all move as one unit simultaneously to maintain spinal alignment; no bending, twisting, or flexion permitted D) Raise the head of the bed to 45 degrees first, then turn — the Fowler's position reduces lumbar strain during repositioning

The correct answer is C. Log roll is the mandatory repositioning technique for all post-spinal surgery patients. A minimum of 3 persons is required, with one designated leader at the head/neck who coordinates all movements. The entire body must move as a rigid unit simultaneously — this maintains spinal alignment and prevents torsional stress on the surgical site, instrumentation, and healing bone graft. Allowing the patient to twist independently (A) could displace pedicle screws or disrupt the fusion site. Two-person repositioning with each person moving their section (B) risks creating a "hinge" at the surgical site. Raising the head of bed (D) creates lumbar flexion which is contraindicated (one of the 3Bs restrictions).

Q4. A 38-year-old construction worker underwent emergency L4/L5 discectomy for a large disc herniation causing right leg weakness. Pre-operatively, right ankle dorsiflexion power was 2/5 (unable to lift against gravity). Eight hours post-operatively, his right ankle dorsiflexion is now 4/5. Regarding this finding, which statement is CORRECT?

A) This is a NEW post-operative deficit — notify the surgical team immediately for emergency return to theatre B) This represents improvement from baseline (pre-op 2/5 → post-op 4/5) — document as improvement; continue neurological monitoring as scheduled; reassure patient that further recovery expected C) Motor power of 4/5 indicates significant impairment — restrict all mobilisation until power returns to 5/5 D) Nerve recovery after discectomy is not expected until 6 weeks post-operatively — this finding is too early to be real recovery

The correct answer is B. This is NOT a new deficit — it is IMPROVEMENT from the pre-operative baseline. The pre-operative power was 2/5 (movement only in horizontal plane, unable to lift against gravity). The post-operative power is 4/5 (movement against resistance, near-normal). This improvement indicates successful nerve root decompression. The nurse must ALWAYS compare post-operative findings against the PRE-OPERATIVE BASELINE — not against normal values. A finding of 4/5 would be alarming as a new deficit in someone who was 5/5 pre-op, but represents significant recovery in someone who was 2/5 pre-op. Nerve recovery can begin very rapidly after decompression — immediate improvement is frequently seen.
