The 1000 lumbar spine radiograph study

Abstract

Magnetic resonance imaging is being increasingly used to optimize the diagnostic process for low back pain and to manage the risk of missing life-threatening pathology. The aim of the study was to examine the care pathway of low back pain with respect to the utilisation of CT and MRI service utilisation. A descriptive, retrospective, cross-sectional study was performed. A random sample of 1000 primary care patients presenting with low back pain who underwent lumbar spine radiography within a specified period was explored. 20% (n=198) of patients who underwent lumbosacral spine X-ray were referred for MRI investigation. Subsequently, 15 (7.6%) patients underwent joint infiltration whilst 6 (3%) patients underwent neurosurgical intervention during 2 years of follow-up. Such findings provide information for policy makers about the utility of MRI and CT scans.
