This report is being filed after the review of the following journal article: d¿oria s, et al.(2021), traumatic compression fractures in thoracic-lumbar junction: vertebroplasty vs conservative management in a prospective controlled trial, j neurointervent surg, pages 1-6, (italy).This article aims to compare the outcomes of conservative management to those of vertebroplasty, a relatively safe and simple procedure.Between january 2012 and february 2016, 102 patients presenting with a single-level, post-traumatic a1 or a2 mager l type fracture, affecting the thoracic-lumbar spine without any neurological deficits were included in the study.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.The first group (group a) included 52 patients (30 males, mean age of 46.6 years), treated with bed rest for 2 weeks then were gradually mobilized and had to wear a brace with 3 support points (tlso brace) when standing or sitting for a further 4 weeks.The second group (group b) of 50 patients (25 males, mean age of 44.3 years) underwent a percutaneous vertebroplasty.Treatment was performed at an average 2.3 days after the trauma (range 1¿4) and patients were kept on bed rest prior to it.All surgery treatments were carried out using the kit ¿unknown depuy spine confidence spinal cement system¿.Patients were then mobilized as early as 6 hours after the procedure unless the residual pain did not allow it.Complications were reported as follows: 16 patients had leakage of cement into the adjoining disc space, the paravertebral space, or into a vein.In all cases the cement leakage was clinically silent: there were no further surgical or medical complications among the operated patients.This report is for the unknown depuy spine confidence spinal cement system.
