OPEN SURGICAL VS. MINIMALLY INVASIVE TREATMENT OF THORACOLUMBAR AO FRACTURES TYPE A AND B1 IN A REFERENCE HOSPITAL

ABSTRACT Objective: The thoracolumbar spine trauma represents 30% of spinal diseases. To compare the minimally invasive technique with the open technique in lumbar fractures. Method: A prospective, cross-sectional, comparative observational study, which evaluated the following variables: surgery time, length of hospital stay, transoperative bleeding, postoperative pain, analyzed by SPSS software using Student's t test with statistical significance of p ≥ 0.05, with 24 patients with single-level thoracolumbar fractures, randomly treated with percutaneous pedicle screws and by open technique with a transpedicular system. Results: The surgery time was 90 minutes for the minimally invasive technique and 60 minutes for the open technique, the bleeding was on average 50 cm3 vs. 400 cm3. The mean visual analogue scale for pain at 24 hours of surgery was 5 for the minimally invasive group vs. 8 for the open group. The number of fluoroscopic projections of pedicle screws was 220 in the minimally invasive technique vs. 100 in the traditional technique. Quantified bleeding was minimal for percutaneous access vs. 340 cm3 for the traditional system. The hospital discharge for the minimally invasive group was at 24 hours and at 72 hours for those treated with open surgery. Conclusions: It is a technique that requires longer surgical time, with reports of less bleeding, less postoperative pain and less time for hospital discharge, reasons why it is supposed to be a procedure that requires a learning curve, statistical significance with respect to bleeding, visual analogue scale for pain and showed no significant difference in the variables of surgical time.
