Comparison of intraoperative and postoperative outcomes between open, wiltse, and percutaneous approach to traumatic thoracolumbar spine fractures without neurological injury: A systematic review and meta-analysis.

Background: Traumatic thoracolumbar fracture fixation without neurological injury can be performed using the traditional open, mini-open Wiltse, and percutaneous approaches. This systematic review and meta-analysis aims to compare perioperative outcomes between these approaches.

Methods: PubMed, Web of Science, Scopus, Embase, and the Cochrane Library were searched for all relevant observational comparative studies.

Results: 5 randomized trials and 22 comparative cohort studies were included. Compared to the traditional open approach (n=959), the Wiltse approach (n=410) was associated with significantly lower operative time, intraoperative estimated blood loss (EBL), and length of stay (LOS). There was no significant difference between the two in terms of postoperative visual analog scale (VAS) and Cobb angle. Compared to the percutaneous approach (n=980), the Wiltse approach was associated with shorter operative and fluoroscopy time, as well as significantly improved Cobb and vertebral body angles. The percutaneous approach was associated with improved vertebral body height. There was no significant difference between the two for blood loss, postoperative VAS, or LOS. Compared to the traditional open approach, the percutaneous approach was associated with shorter operative time, lower EBL, shorter LOS and better postoperative VAS and Oswestry Disability Index. There was no difference between the two in postoperative Cobb angle, vertebral angle, or vertebral body height. Overall study heterogeneity was high.

Conclusions: Utilization of minimally invasive surgical approaches holds great promise for lowering patient morbidity and optimizing care. A prospective trial is needed to assess outcomes and guide surgical decision making.
