ABSTRACT
OBJECTIVE: To assess long term outcomes of aggressive rehabilitative treatment on canalicular sequestered lumbar disc herniations METHOD: Clinical outcomes of twenty four patients with sequestered disc herniation with symptomatic radicular pain were evaluated prospectively and longitudinally for one year. All patients received aggressive rehabilitative treatment including transforaminal epidural steroid injection, pelvic stabilization exercise, physical therapy, and back school. Clinical outcomes were measured by visual analogue scale (VAS) for back and radicular pain, Oswestry Disability Index (ODI) for back pain before treatment, posttreatment one, three, six, and twelve months. After twelve months, we categorized patients' satisfaction. Four patients were dropp RESULTS: The averages of VAS for lower extremity and back pain reduced significantly from 6.6 and 5.8 at pretreatment to 0.7 and 0.9 at 12 months posttreatment, respectively (p<0.001). The averages of ODI reduced significantly from 73.5% at pretreatment to 22.3% at posttreatment 12 months (p<0.001). Sixteen of twenty patients (80.0%) were satisfied with their current status posttreatment 12 months. CONCLUSION: Sequestered disc herniations could be treated successfully by aggressive rehabilitative treatment. Clinical improvement was achieved from posttreatment one month and persisted for twelve months. Operation might be delayed until aggressive rehabilitation treatment fail to treat sequestered disc herniations.
