Abstract
The present prospective study was conducted on 300 adult patients with low back pain (LBP) who were sampled from those attending the Radio Diagnosis Department, Faculty of Medicine, El-Minia University along the period from March to September, 2015.
This study aimed to: (1) assess the association between lumbar magnetic resonance imaging (MRI) findings and low back pain (LBP) with and without sciatica among Egyptian population, and (2) identify how individual and occupational characteristics would contribute to the risk of LBP.
All the study patients were subjected to:
• Thorough clinical history with special attention to the following categories:
• Sociodemographic factors; such as: age, sex, residence, smoking, occupation, marital state and parity.
• Working conditions; such as: duration of current work, average working hours/day, and duration of absence from work in the last year.
• Low back pain characteristics; such as: type of pain, site, weather associated with sciatica or not and frequency of pain episodes during the preceding 12 months. Pain modifying factors as rest, activity, changes in position and weight bearing, and accompanying symptoms such as stiffness, numbness, parathesia, weakness, urinary retension and incontinence were evaluated as well.
• Careful clinical examination: including measurement of body weight and height and calculation of body mass index (BMI). It also included thorough examination of spines and paravertebral muscles and complete neurological examination including straight leg raising test. Review of other body systems was done to check the extra-spinal causes of LBP.
• Lumbar spine MRI: It was performed according to the instructions reported by Borenstein et al. (2001):
The present study revealed that, the majority of patients were females 154(51.3%), belonged to the age group of 38-<58 years 137(45.7%), rural 206(68.7%), with low educational levels 129(43%) non-worker 146(48.7%), married 267(89%), had > 3 offsprings in females 122(79.2%) and males 101(69.2%), non-smoker 199(66.3%) and obese 162(54%).
