A Survey on Low Back Pain Risk Factors in Steel Industry Workers in 2015

STUDY DESIGN: This was a cross-sectional study. PURPOSE: The aim of this study was to determine the prevalence of low back pain (LBP) and its association with individual factors and current job status among steel industry workers in Mashhad, Iran. OVERVIEW OF LITERATURE: Several studies have been conducted on LBP and its related risk factors, some of which emphasized oc-cupational factors as the main etiology of LBP. Meanwhile, individual risk factors have been emphasized in other studies. Despite several published articles, there are still many unresolved, basic issues about developing LBP. METHODS: For this study, 358 male workers were selected by a random sampling method and divided into two groups: production workers (n=201) and administrative personnel (n=157). Data were collected using modified Nordic questionnaire and physical examination. Statistical analysis was performed to identify the correlation between individual factors and current job status with LBP. RESULTS: Despite the young age of participants and their short employment duration, the overall prevalence of LBP was high (32.4%) in this industry. The prevalence of non-specific LBP in production workers and administrative personnel was 26.8% and 21.0%, respectively. Disk herniation was observed in 10.4% of production workers and 6.3% of administrative personnel. Age, employment duration, body mass index and smoking status were similar in the two groups. There was no significant relationship between LBP and current job status; however, a significant relationship was found between prevalence of LBP with age, duration of employment, and leisure time physical activity (p<0.05). CONCLUSIONS: We have not found any relationship between LBP and current occupational status suggesting that the effects of general health-related factors such as weight, age, leisure time physical activity, and duration of employment are more important than occupational factors in developing LBP.

Sciatica in a Five-Year-Old Boy

The prevalence of back pain during childhood is 50%; in 22% of these cases, a specific diagnosis can be found. Osteoid osteoma is a rare benign tumor that occursonly in 20% of cases and involves the spine. The aim of this report is to explain an atypical case of lumbar osteoid osteoma with significant neurologic deficit at a very young age. A five-year-old boy was presented with refractory pain in the low back and left extremity for approximately one year. Positive clinical findings were antalgic gait, stiff lumbar spine, weak left big toe extension force and a positive straight leg rising test on the left side. Paraclinical studies revealed osteoid osteoma in the left-sided pedicle of the fifth lumbar vertebra. With surgical excision, he recovered immediately. Lumbar osteoid osteoma should be suspected as the cause of low back pain or sciatalgia in any young patient.
