Postpartum Unilateral Sacral Stress Fracture Mimicking Lumbar Radiculopathy: Case Report

Abstract

Postpartum sacral stress fracture is a very rare clinical entity. Because of the ambiguous clinical and radiological findings, it is often diagnosed late. A case of a postpartal 25-year-old female patient presented with acute onset of low back pain radiating to the right extremity, mimicking lumbar radiculopathy. Magnetic resonance imaging of sacrum revealed a non-displaced stress fracture of the right sacral ala. The 25-hydroxy vitamine D level of the patient was very low; dual energy X-ray absorptiometry measurements were in the normal range. The patient is completely cured as a result of conservative treatment. As a result, sacrum stress fracture should be kept in mind in the presence of back pain during pregnancy and postpartum period.
