Abstract |
Background |
Thoracolumbar fractures are a public health issue due to their severity and frequency. Management varies according to demographic, clinical and radiologic features, from non-operative treatment to extensive fusion. In the two last decades, improvements and new techniques have emerged, such as kyphoplasty and percutaneous approaches. The main goal of this study was to describe the management of thoracolumbar fractures in France in 2018.
Hypothesis |
The study hypothesis was that management of thoracolumbar fractures in France has progressed in recent decades.
Material and methods |
The files of 407 adult patients operated on between January 1, 2015 and December 31, 2016 for T4-L5 thoracolumbar fracture in 6 French teaching hospitals were retrospectively reviewed, at a mean follow-up at 10.2±8.2 [1; 42] months. Demographic, surgical and postoperative radiological data were collected. p-values<0.05 on Student test were considered significant.
Results |
Five hundred and thirty-one fractures were analyzed (27% of patients presented more than one fracture). Surgery consisted in internal fixation for 56% of patients, including 17% with associated kyphoplasty; 29% had fusion, and 15% stand-alone kyphoplasty. Surgery used an open posterior approach in 54% of cases, and a percutaneous approach in 46%. Initial sagittal angulation was not a significant decision criterion for screwing (p=0.8) or for a secondary anterior approach in case of fusion (p=0.6). Immediate postoperative sagittal correction was significantly better with an open than a percutaneous approach (p=0.004), but without significant difference at last follow-up (p=0.8). Correction at last follow-up was significantly better with anterior associated to posterior fusion (p=0.003).
Discussion |
Management of the thoracolumbar fractures has progressed in France in recent years: 46% of surgeries used a percutaneous approach, compared to 28% in 2013; 90% used a posterior approach only, compared to 83% in 2013; rates of combined approach were unchanged, at 6%. Twenty-five percent of burst fractures were treated by fusion, possibly due to lack of preoperative MRI in 79% of cases.
Level of evidence |
IV, retrospective cohort study.
