OBJECTIVE: To evaluate the outcomes of intensive conservative treatment on extraforaminal lumbar disc herniations. METHOD: Twenty five patients with extraforaminal lumbar disc herniations with symptomatic radicular pain were included. Under fluoroscopic guidance, 40 mg of triamcinolone was infused around the nerve root after provocation of patient's usual radicular pain. Lumbosacral dynamic stabilization exercise, thermal and electrical therapy, and education of posture correction were added. The clinical outcomes were measured by visual analogue scale (VAS) and Oswestry disability index (ODI) before treatment, one, three, six, and twelve months after the treatment. After twelve months, patients' satisfaction was classified to four categories: excellent, good, fair, or poor. Four patients were dropped out. RESULTS: Follow-up VAS and ODI significantly decreased since post-treatment one month (p<0.0001). The average score of VAS for lower extremity and back pain reduced significantly from 6.6, 4.5 at pretreatment to 1.5, 1.9 at 12 months post-treatment, respectively (p<0.0001). The averages of ODI reduced significantly from 65.4% at pretreatment to 25.4% at post-treatment 12 months (p<0.0001). In patients' satisfaction, seventeen patients (81.0%) were recorded as excellent or good after post-treatment 12 months. CONCLUSION: Intensive conservative treatment was effective on patients who underwent extraforaminal lumbar disc herniation. Pain relief and functional improvement sustained for 12 months.
