  Background: Literature recommends that refractory cases with lumbar disc herniation and appropriate indications are better to be treated surgically, but do all the patients throughout the world consent to the surgery with a same disability and pain threshold? We aim to elucidate the prevalence and severity of disabilities and pain in Iranian patients with lumbar disc herniation who have consented to the surgery.   Methods: In this case series study, we clinically evaluated ۱۹۴ (۸۱ female and ۱۱۳ male) admitted patients with primary, simple, and stable L۴-L۵ or L۵-S۱ lumbar disc herniation who were undergoing surgical discectomy. The mean age of the patients was ۳۸.۳±۱۱.۲ (range: ۱۸-۷۶ years old). Disabilities were evaluated by the items of the Oswestry Disability Index (ODI) questionnaire and severity of pain by the Visual Analogue Scale (VAS). Chi-square test was used to compare the qualitative variables. Results: Severe disability (۳۹.۲%) and crippled (۲۹.۹%) were the two most common types of disabilities. Mean ODI score was ۵۶.۷±۲۱.۱ (range: ۱۶-۹۲). Total mean VAS in all patients was ۶.۱±۱.۹ (range: ۰-۱۰). Sex and level of disc herniation had no statistical effect on preoperative ODI and VAS. The scale of six was the most frequent scale of preoperative VAS in our patients. Conclusion: Iranian patients with lumbar disc herniation who consented to surgery have relatively severe pain or disability. These severities in pain or disabilities have no correlation with sex or level of disc herniation and are not equal with developed countries.
