Is traction in the lateral‑flexion position (TILF) without physiotherapy indicated for a patient with low‑grade L5‑S1 anterolisthesis that progresses from Grade I to Grade II on standing X‑ray?

TILF Without Physiotherapy is NOT Indicated for Low-Grade L5-S1 Anterolisthesis

For Grade I-II L5-S1 anterolisthesis that progresses on standing radiographs, comprehensive conservative management including formal physiotherapy for at least 6 weeks is mandatory before considering any surgical intervention, and "traction in lateral-flexion position" (TILF) alone without physiotherapy does not meet evidence-based treatment criteria. 1

Why TILF Alone is Insufficient

Traction Has No Proven Benefit as Monotherapy

• Strong evidence demonstrates that traction as a single treatment (continuous or intermittent) shows no statistically significant difference in short or long-term outcomes compared to placebo, sham, or no treatment for low back pain with or without sciatica. 2

• Systematic reviews of 24 randomized controlled trials (2,177 patients) found that intermittent or continuous traction as a single treatment for low back pain cannot be recommended for mixed groups of patients with LBP with and without sciatica. 2

• For patients with sciatica specifically, the evidence for traction remains conflicting and inconsistent, with methodological problems in most studies preventing any firm recommendation. 2

Physiotherapy is the Required First-Line Treatment

• The American Association of Neurological Surgeons mandates that lumbar fusion be considered only after chronic low back pain remains refractory to conservative treatment, which includes a comprehensive approach with formal physical therapy for at least 6 weeks. 1

• Proper conservative treatment requires a comprehensive approach, including formal physical therapy, before considering any surgical intervention, with a strength of evidence level of moderate. 1

• The patient's lack of completion of formal physical therapy is a critical deficiency in their conservative treatment according to established guidelines. 1

Evidence-Based Treatment Algorithm for Grade I-II L5-S1 Anterolisthesis

Step 1: Confirm Surgical Criteria Are NOT Met

Dynamic instability (Grade I progressing to Grade II on standing) does NOT automatically warrant surgery. The following must be documented:

• Persistent disabling symptoms despite conservative management for 3-6 months 1
• Imaging findings that correlate with clinical presentation 1
• Documented moderate-to-severe or severe stenosis with neural compression 3
• Evidence of neurological compromise or progressive neurologic deficit 1

Step 2: Initiate Comprehensive Conservative Management (Minimum 6 Weeks)

Required components before any surgical consideration: 1

• Formal supervised physical therapy program lasting minimum 6 weeks to 3 months 1, 3
• Lumbar extension exercises to reduce disc herniation and improve spinal stability 4
• Core stabilization and postural training 5
• Pain management with NSAIDs and muscle relaxers as needed 3
• Neuroleptic medications (gabapentin or pregabalin) for radicular symptoms if present 1
• Activity modification and ergonomic education 5

Step 3: Consider Adjunctive Traction ONLY Within Physiotherapy Program

If traction is used, it must be combined with physiotherapy—never as monotherapy:

• Meta-analyses of low-quality studies suggest supine mechanical traction added to physical therapist treatments had significant effects on pain (effect size = -0.58) and disability (effect size = -0.78) in the short term. 6

• Adding traction to a standard physiotherapy program shows limited evidence of benefit, but traction alone without physiotherapy has no proven efficacy. 2

• Mechanical traction combined with lumbar extension exercises may facilitate improvement in pain and return to function in select cases, but only as an adjunct to comprehensive physiotherapy. 4

When Surgical Intervention Becomes Appropriate

Absolute Indications for Fusion (Not Met by Grade I-II Anterolisthesis Alone)

Fusion is recommended only when ALL of the following are present: 1, 3

• Documented spondylolisthesis with instability (any grade) on flexion-extension radiographs showing >3-4mm translation or >10 degrees angulation 3
• Moderate-to-severe or severe stenosis with documented neural compression at the level corresponding to clinical findings 3
• Failed comprehensive conservative management for minimum 3-6 months including formal supervised PT 1, 3
• Persistent disabling symptoms with significant functional impairment despite conservative measures 1

Evidence Supporting Fusion When Criteria Are Met

• Class II medical evidence demonstrates that 96% of patients with spondylolisthesis and stenosis treated with decompression plus fusion reported excellent or good outcomes, compared to only 44% with decompression alone. 3

• Patients treated with decompression/fusion reported statistically significantly less back pain (p=0.01) and leg pain (p=0.002) compared to decompression alone when instability and stenosis are both present. 3

• In the absence of deformity or instability with neural compression, lumbar fusion has not been shown to improve outcomes in patients with isolated stenosis, and therefore it is not recommended (Level IV evidence). 3

Critical Pitfalls to Avoid

Do Not Pursue TILF as Monotherapy

• Traction without physiotherapy has no evidence base and wastes time that should be spent on proven conservative treatments. 2

• The literature allows no firm conclusion that traction, in a generalized sense, is an effective treatment for patients with LBP when used alone. 2

Do Not Rush to Surgery for Dynamic Instability Alone

• Only 9% of patients without preoperative evidence of instability develop delayed slippage after decompression alone, suggesting that prophylactic fusion is not routinely indicated. 3

• Patients with less extensive surgery tend to have better outcomes than those with extensive decompression and fusion when instability is absent. 3

• Blood loss and operative duration are significantly higher in fusion procedures, and the risks are not justified without meeting all surgical criteria. 3

Do Not Skip Formal Physiotherapy

• Intensive rehabilitation programs with cognitive components show equivalent outcomes to fusion for chronic low back pain without stenosis or instability (Level II evidence). 1

• The patient's lack of completion of formal physical therapy is a critical deficiency that must be addressed before any surgical consideration. 1

Recommended Treatment Plan for This Patient

Initiate 6-12 weeks of comprehensive conservative management: 1, 3

1. Formal supervised physical therapy 2-3 times per week focusing on:

   • Lumbar extension exercises 4
   • Core stabilization and postural training 5
   • Piriformis stretching if sciatic symptoms present 5
   • Gait training and functional mobility 5

2. Pain management:

   • NSAIDs for inflammatory pain 3
   • Muscle relaxers for muscle spasm 3
   • Gabapentin or pregabalin if radicular symptoms develop 1

3. Activity modification:

   • Avoid prolonged sitting, standing, or heavy lifting 5
   • Use assistive devices if needed for stability 1

4. Consider adjunctive treatments ONLY within PT program:

   • Supine mechanical traction may be added to PT if radicular symptoms are prominent 6
   • Epidural steroid injections if radiculopathy develops (though relief is typically <2 weeks) 1

5. Reassess at 6 weeks and 3 months:

   • Obtain repeat flexion-extension radiographs to document progression 3
   • Document persistent symptoms and functional limitations 1
   • Confirm neural compression on MRI if surgical consideration warranted 3

Only after documented failure of this comprehensive conservative approach should surgical fusion be considered, and only if all surgical criteria are met. 1, 3
