RESUMO
INTRODUCTION: Longitudinal sacral fractures are usually a matter of controversy regarding decision-making for reduction, fixation, and approach. Percutaneous and minimally invasive techniques present perioperative difficulties, but with fewer postoperative complications compared to open techniques. The objective of this study was to compare the functional as well as radiological outcomes of the Transiliac Internal fixator (TIFI) versus Iliosacral screw (ISS) fixation of sacral fractures applied percutaneously in a minimally invasive technique. METHODS: A Prospective comparative cohort study was conducted in a level 1 trauma center in a university hospital. The study included 42 patients with complete sacral fractures, 21 patients have been allocated to each group (TIFI group & ISS group). The clinical, functional, as well as radiological data, were collected and analyzed for the 2 groups. RESULTS: The mean age was 32 (18 -54 years), and the mean follow-up was 14 (12 -20 months). There was a statistically significant difference in favor of the TIFI group regarding a shorter operative time (P = 0.04) as well as less fluoroscopy time (P = 0.01) whereas there was less blood loss in the ISS group (P = 0.01). Both the mean Matta's radiological score, the mean Majeed score as well as the pelvic outcome score were comparable between the 2 groups with no statistically significant difference. CONCLUSION: This study suggests that both TIFI and ISS through a minimally invasive technique represent valid methods for sacral fracture fixation with a shorter operative time, less radiation exposure in TIFI and less blood loss in the ISS. However, the functional, as well as radiological outcomes, were comparable between the 2 groups.
