Abstract
Background
No consensus exists for the management of unstable thoracolumbar (TL) burst fractures. Surgical options include anterior, lateral, or posterior stabilization (or a combination), depending on the fracture. The potential benefits of anterior reconstruction come with increased operative time and associated morbidity. A posterior-only approach can offer stable correction without increased operative risks but may result in loss of kyphotic correction over time.
Purpose
To determine whether posterior-only stabilization is a viable treatment option for patients with traumatic TL fractures as opposed to anterior and combined approaches.
Methods
We performed a retrospective analysis of adult patients with TL burst fractures who underwent posterior-only surgical intervention from 2005 to 2015. Operations were performed at two levels above and below the fractured segment using pedicle screw-rod fixation constructs with autograft and allograft. All patients received TL bracing for at least three months. Patients lost to followup were excluded.
Results
Sixty-four consecutive patients with posterior-only stabilization were identified, with 18 lost to followup. Of the remaining 46 patients, 93% (n=43) were male and 7% (n=3) were female, with a mean age of 36.8 years. All patients were followed for 12 months. The mean time until the removal of the brace was 3.54 months. No patients required additional surgical intervention for spinal stabilization. Three patients experienced postoperative complications, all of which were related to infection.
Conclusions
Our data indicate that posterior-only stabilization for traumatic TL burst fractures is a durable and effective option in select patients. The approach offers surgical intervention with a decreased perioperative risk as well as reduced morbidity and mortality, with a minimal increase in the risk of kyphotic deformity. Further prospective studies are necessary to validate these findings clinically.
