The Outcome of Minimally Invasive Percutaneous Transpedicular Screw Fixation (TPSF) in Thoracolumbar Spine Fractures

Abstract

Background & Objective:  This study aimed to determine the outcome of percutaneous transpedicular screw fixation (TPSF) in patients with thoracolumbar fractures. Material & Methods:  A total of 157 patients with thoracolumbar fractures were included from the Department of Neurosurgery, LGH, PINS, Lahore. Patients were evaluated with plain X-rays, CT, and MRI scans. Neurological status was documented preoperatively and postoperatively. All patients were treated with Minimally Invasive Percutaneous Transpedicular screw fixation. Data for operative time and per-operative blood loss was obtained through the operative notes. The severity of postoperative pain and length of hospital stay were also documented. Results:  Out of 157 patients, 69.4% were male and 30.6% were female. The 141 (89.8%) were traumatic from road traffic accidents/falls, and 16 (10.2%) were pathologic. The 128 (81%) patients were discharged on the first day, 23(15%) were discharged on the second day, and 6(3.8%) on the third day. 79% of patients had a single level of spine fracture whereas, 20% had 2 spinal fracture levels. The average operative time for MIS percutaneous TPSF was 55 minutes. Postoperative pain was markedly reduced as compared to traditional open surgery and no patient had any new neurological deficit. The mean blood loss was 25 ml and none of the patients needed a postoperative blood transfusion. Conclusion:  Percutaneous transpedicular instrumentation is an ideal surgical approach for thoracolumbar spinal stabilization.
