Traumatic compression fractures in thoracic-lumbar junction: vertebroplasty vs conservative management in a prospective controlled trial

Background Both surgery and conservative management are well established treatments for compression fractures of the thoraco-lumbar spine without neurological compromise. This article aims to compare the outcomes of conservative management to those of vertebroplasty, a relatively safe and simple procedure. Methods 102 patients were admitted to our neurosurgical unit between January 2012 and February 2016, presenting with a single-level, post-traumatic A1 or A2 Mager l type fracture, affecting the thoracic-lumbar spine without any neurological deficits. After description of both treatment options, the patients were asked to choose between vertebroplasty or conservative treatment. Accordingly, the patients were allocated into two groups and a prospective non-randomized controlled trial was carried out. The first group (Group A) included 52 patients, treated with bed rest and an orthosis. The second group (Group B) of 50 patients underwent a percutaneous vertebroplasty. Pain intensity (assessed via visual analog scale (VAS)), disability degree (assessed via Oswestry Disability Index), ability to resume work (assessed via Denis work Scale), vertebral body height loss rate, regional kyphosis angle (Cobb’s angle), duration of hospitalization and treatment-associated complications, were prospectively recorded in a database and analyzed. Follow ups were planned at 1, 6, and 12 months after the injury. Results Group B, compared with group A, showed a faster improvement in VAS score as well as functional ability and return to work. Cobb’s angle progression was significantly less in the surgical group. Morbidity, mortality, and complication rate were similar and comparable in both groups without a statistical difference (P<0.05) Conclusions Vertebroplasty is a safe and effective treatment in post-traumatic thoracic-lumbar fractures compared with conservative management.
