Objective: The objective of this study was to analyze the results of surgical treatment of patients with unstable injuries of the thoracolumbar spine using simultaneous minimally invasive corpectomy and percutaneous transpedicular stabilization. Materials and Methods: The retrospective study included 34 patients with isolated single-level unstable injuries of the thoracolumbar spine (5 or more points according to the Thoracolumbar Injury Classification and Severity Score (TLICS), operated on from the moment of injury from 8 to 24 h using the technique of minimally invasive corpectomy and percutaneous transpedicular stabilization simultaneously. The technical features of surgery, clinical data (pain level according to the Visual Analog Scale, quality of life according to the SF-36 questionnaire, subjective satisfaction with the operation according to the MacNab scale, and the presence of complications), and instrumental data (angle of segmental kyphotic deformity and sagittal index to and after surgery). The assessment of clinical data was carried out before surgery, at discharge, after 6 months, and in the long-term period, on average, 30 months after surgery. Results: When evaluating the clinical data, a significant decrease in the severity of pain syndrome was found on average from 90 mm to 5.5 mm in the late follow-up (P < 0.001), as well as a significant improvement in the physical and psychological components of health according to the SF-36 questionnaire on average from 28.78 to 39.26 (P < 0.001), from 36.93 to 41.43 (P = 0.006), respectively. In the long-term period, according to the MacNab scale, the patients noted the result of the operation: excellent – 18 (52.9%), good – 13 (38.3%), and satisfactory – 3 (8.8%); no unsatisfactory results were registered. Four (11.8%) perioperative surgical complications were registered, which were successfully treated conservatively. A significant restoration of the sagittal profile with an insignificant change in blood pressure was recorded in the long-term postoperative period. An average follow-up assessment of 30 months according to the American Spinal Injury Association scale showed the presence of E and D degrees in 85.4% of patients. Conclusion: Minimally invasive corpectomy with percutaneous transpedicular stabilization in the treatment of patients with unstable injuries of the thoracolumbar spine can effectively eliminate kyphotic deformity and prevent the loss of its reduction with a low number of postoperative surgical complications. The technique has minimal surgical trauma with the possibility of early postoperative rehabilitation and provides a significant stable reduction in vertebrogenic pain syndrome, improvement of neurological deficits, and restoration of the quality of life of patients and in the follow-up.
