THE ROLE OF DYNAMIC LUMBAR SPINE X-RAY IN THE DIAGNOSIS OF TYPE 1 SPONDYLOLISTHESIS IN PATIENTS WHO HAVE PREVIOUSLY DONE LUMBAR SPINAL SURGERY.

Abstract

Objective: To determine the role of dynamic lumbar spine x-ray in the diagnosis of type 1 spondylolisthesis in patients who have previously done lumbar spinal surgery.
 Materials and Methods: The study was carried out at neurosurgery department, Lady Reading Hospital Peshawar, KPK from July 2015 to June 2017. He study employed prospective observational) study and a total of 1440 patients were studied.
 Results: A total of 1440 patients were studied in which 974 (67.7%) were females and the remaining 464 (33.3%) were males. Mean age of the patients was between 20 to 50 years. These patients had underwent lumbar spinal surgery about 1 year ago for PIVD and Stenosis. Proper history was taken and relevant examination was done. These patients were suggested dynamic lumbar spinal x-ray .After dynamic lumbar spinal x-ray (flexion extension view) was done, it was revealed that around 672 (46.6 %) of the total 1440 patients had type 1 spondylolisthesis. This percentage of patients with type 1 spondylolisthesis is prove of how dynamic lumbar spinal x-ray plays a role in the diagnosis of type 1 spondylolisthesis in patients who have had underwent lumbar spinal surgery.
 Recommendation: Dynamic lumbar spinal x-ray is recommended as a standard technique in the diagnosis of type 1 spondylolisthesis in patients who had previously underwent lumbar spinal surgery.
