Outcome Measures
Primary Outcomes (2)
Change in Oswestry Disability Index (ODI)
0% to 20%: minimal disability: The patient can cope with most living activities. Usually no treatment is indicated apart from advice on lifting sitting and exercise. 21%-40%: moderate disability: The patient experiences more pain and difficulty with sitting, lifting and standing. Travel and social life are more difficult and they may be disabled from work. Personal care, sexual activity and sleeping are not grossly affected and the patient can usually be managed by conservative means. 41%-60%: severe disability: Pain remains the main problem in this group but activities of daily living are affected. These patients require a detailed investigation. 61%-80%: crippled: Back pain impinges on all aspects of the patient's life. Positive intervention is required. 81%-100%: These patients are either bed-bound or exaggerating their symptoms.
Preoperatively. 6 weeks, 3 months, 6 months and 12 months post-operatively
Change in Roland Morris Disability Questionnaire (RMDQ)
This is a 24 item questionnaire. The patient is asked to tick a statement when it applies to him that specific day, this makes it possible to follow changes in time. The end score is the sum of the ticked boxes. The score ranges from 0 (no disability) to 24 (max. disability)
Preoperatively. 6 weeks, 3 months, 6 months and 12 months post-operatively
Secondary Outcomes (3)
Back Pain Numerical Rating Score (BPNRS)
Preoperatively. 6 weeks, 3 months, 6 months and 12 months post-operatively
Leg Pain Numerical Rating Score (LPNRS)
Preoperatively. 6 weeks, 3 months, 6 months and 12 months post-operatively
Modified MacNab Criteria
Preoperatively. 6 weeks, 3 months, 6 months and 12 months post-operatively
Study Arms (2)
Group A
group A undergoing TELD (transforaminal endoscopic lumbar discectomy) with electromagnetic navigation system
Group B
group B undergoing TELD with X-ray fluoroscopy (gold standard)
Interventions
The aim of this study is to assess the safety and efficacy of TELD assisted by electromagnetic navigation for treating lumbar disc herniation (LDH).
Eligibility Criteria
20 consecutive patients, group A undergoing TELD with electromagnetic navigation system vs. group B undergoing TELD with X-ray fluoroscopy (gold standard). Parameters: gender, age, body mass index, neurological examination, comorbidities (diabetes, AHT, depression, smoking, work status, other joint problems), recurrence of disc herniation, follow-up time, pain evaluation on the day before surgery (numerical rating scale), herniation level, type of herniation (disc protrusion, disc prolapsed, disc extrusion or sequestered disc), duration of preoperative back pain/leg pain, use of analgesics (type and duration), preoperative Roland-Morris disability questionnaire, preoperative Oswestry Disability Index.
You may qualify if:
- age≥18 and ≤80 years;
- typical clinical symptoms and consistent imaging evidence of mono-radiculopathy LDH; or single level LSS combined with disc herniation
- recalcitrant pain despite proper conservative therapy (including analgesics, NSAIDs, corticoids infusion under CT guidance and physical therapy) for at least 3 months before surgery and/or neurological deficit in the territory of the irritated nerve root
- VAS pain ≥ 6/10
- Absence of significant instability;
You may not qualify if:
- serious underlying disease or mental illnesses
- severe central stenosis, cauda equina syndrome, spinal instability, active infection, and serious calcified fragments
- previous lumbar treatment with spinal surgery, ozone intervention, or radiofrequency ablation
- unwilling or unable to participate in treatment and complete follow-up
- Multi-level disc pathology
- MRC paresis \<4/5
- Pregnancy
- participation in another clinical trial
