Study Design:
Retrospective review.
Objective:
Report the 2-year operative and clinical outcomes of these service members with low lumbar fractures.
Summary Of Background Data:
The majority of spinal fractures occur at the thoracolumbar level, with fractures caudal to L2 accounting for only 1% of spine fractures. A previous report from this institution regarding combat-related spine burst fractures documented an increased incidence of low lumbar burst fractures in injured service members.
Methods:
Review of inpatient and outpatient medical records in addition to radiographs for all patients treated at our institution with combat-related burst fractures occurring at the L3-L5 levels.
Results:
Twenty-four patients with a mean age of 28.1± 7.2 underwent surgery for low lumbar (L3-L5) burst fractures. The mean number of thoracolumbar levels injured was 2.9 ± 1.4. Eleven patients had neurological injury, 4 of which were complete. The mean days to surgery were 16.8 ± 24.5. The mean number of levels fused was 4.3 ± 2.1, with fixation extending to the pelvis in 4 patients (17%). Fourteen (61%) patients had at least 1 postoperative complication, with 7 (30%) requiring reoperation. Five patients had a postoperative wound infection. Five patients had deep venous thromboses, 3 had pulmonary emboli. Mean clinical follow-up was 3.3± 2.2 years. At latest follow-up, all were separated from military service, 10 experienced persistent bowel/bladder dysfunction, 15 had lower extremity motor deficits, and 10 had documented persistent low back pain. Nineteen had chronic pain with 18 patients still taking pain medications and/or muscle relaxers.
Conclusion:
Low lumbar burst fractures are a rare injury with an increased incidence in combat casualties engaged in the wars in Iraq and Afghanistan. We found a high rate of acute postoperative complications (61%), as well as a high reoperation rate (30%). At approximately 3 years of follow-up, most of these patients had persistent neurological symptoms and chronic pain.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
