INTRODUCTION:Low back pain (LBP) is common in pregnancy affecting approximately 50% of pregnant women. Yet, there is much ambiguity with regard to the diagnostic work-up and management of pregnant women with LBP. This narrative review summarizes evidence surrounding investigations, management strategies and the considerations around performing neuraxial blocks for pregnant women with LBP to inform clinical practice.METHODS:MEDLINE, MEDLINE In-Process and Embase were searched from inception to November 2015. The search was limited to humans and restricted to the English language. All studies from case reports to randomized controlled trials describing diagnostic modalities, management strategies and use of neuraxial techniques during labor and delivery in pregnant women with LBP were identified.RESULTS:A total of 6803 records were identified through database-searching and 60 through citation-tracking, of which 77 studies were included. Of these, 32 described the use of diagnostic modalities, 56 described management strategies, and three reported the use of neuraxial techniques for labor and delivery. Magnetic resonance imaging is the safest diagnostic modality for LBP in pregnancy. Antenatal educational programs, exercise and steroid injections into the epidural space or sacroiliac joints may help with pain management. Worsening neurological deficits, vertebral fractures, and tumors may need surgical management. There is limited evidence on challenges of performing neuraxial blocks in the peripartum period but there is a potential for increased risk of neurological complications in parturients with pre-existing neurological deficits.CONCLUSION:This review summarizes the available evidence and provides a clinical algorithm for the diagnosis and management of pregnant women with LBP.
