Validation of thoracolumbar injury classification and Severity Score in the management of acute and subacute Osteoporotic vertebral compression fractures - A pilot study and a suggested modification.

To retrospectively assess the Thoracolumbar Injury Classification and Severity Score (TLICS) in patients with osteoporotic vertebral compression fractures (OVCF) and compare the treatment given with that predicted by the TLICS score. All medical records of patients presenting from January 2014 to November 2017 for acute atraumatic or low impact OVCF were screened, and eligible patients were retrospectively reviewed. The TLICS score was determined based upon magnetic resonance imaging (MRI) findings and clinical records. Clinical records (including pain score data), imaging data, operative procedures, and stability of neurological examination were tracked over three months for each patient. Of the 56 patients included, 36 patients had a TLICS score of 1, 18 had a TLICS score of 2, and two had a TLICS score of 4. Only one patient with a TLICS score of 4 underwent surgical stabilization, while the rest of the cohort was managed non-operatively, with or without kyphoplasty. TLICS score 1 corresponded to simple compression and TLICS score 2 corresponded to burst morphology with retropulsion and without neurological deficits. Of the patients with a TLICS score of 1 and 2 who underwent kyphoplasty, there was a statistically significant improvement in pain scores in both groups; however no significant difference was observed, between each TLICS score (i.e., 1 or 2). None of the patients developed instability or neurological decline. TLICS score correctly predicted operative versus non-operative management in all patients with OVCF. TLICS may be used in making management decisions, and in the triage of these patients for operative versus non-operative evaluations. Our study suggests that patients with TLICS score of 4 or higher require surgical evaluation, while those with TLICS of 1 or 2 are likely to have satisfactory non-surgical management with augmentation or conservative care. In general, patients with OVCF typically present with low TLICS score. Kyphoplasty appears to be similarly beneficial in patients with a TLICS score of 1 or a TLICS score of 2. A modification of the TLICS score by adding TLICS Zero to include uncompressed OVCF with edema is suggested. The limitations of this study include a small size; a larger study is needed to confirm these findings.
