Abstract
Hip and low back pain is common during pregnancy or postpartum period. Herein, we report 12 cases with low back pain radiating to hip and buttocks presented to us after delivery and after failed NSAID therapy. MRI was very valuable and helped us in early diagnosis and promt treatment. We treated all patients with course of oral steroids and emperical antibiotic therapy in whom there was leuckocytosis. All patients responded very well to our treatment protocol. We recommend early MRI and oral steroids for fast recovery of postpartum - associated inflammatory sacroiliitis.
