Management of thoracolumbar injury classification and severity score of 4 (TLICS=4) thoracolumbar vertebra fractures: Surgery versus conservative treatment.

BACKGROUND

This study aims to compare clinical and radiographic outcomes of surgical treatment and conservative treatment with bracing in neurologically intact patients with score 4 of TLICS thoracolumbar vertebra fractures.

METHODS

Patients with traumatic thoracolumbar junction fractures (T11-L2), the score of TLICS 4, and minimum 24-month follow-up were included in this study. Patients were divided into surgery and bracing groups. The groups were compared concerning clinical and demographical features, local kyphotic angles (LKA), vertebra height loss percentage (VHL), Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and time to return to work.

RESULTS

There were 74 patients (71 males, 3 females) in the surgery group and 76 patients (58 males, 18 females) in the bracing group. Although the surgery group showed better improvement in VAS scores within six months postoperatively, no significant difference was observed at the 24th-month evaluation (p<0.001 and p=0.270, respectively). ODI, LKA and VHL were significantly lower in the surgery group (p<0.001, p<0.001 and p<0.001, respectively). In addition, return to work was significantly earlier in the surgery group (p<0.001).

CONCLUSION

The findings obtained in this study suggest that the surgical treatment for TLICS 4 patients with thoracolumbar fractures has better clinical and radiographic outcomes than the bracing. Moreover, returning time to the work of patients is shortened with surgical treatment. The surgical treatment seems to be the first and the appropriate choice in the management of TLICS 4 thoracolumbar vertebral fractures.
