Fusion-less short posterior segmental fixation in thoracolumbar fractures

Authors

Abstract

Background
The purpose of this study was to evaluate the effectiveness of short posterior fixation without fusion in treatment of thoracolumbar fractures.
Patients and methods
In a prospective study, 64 consecutive patients with types A3.2 and A3.3 thoracolumbar fractures were operated by pedicle screws fixation a level above and below the fracture without fusion followed by physiotherapy.
Results
The mean follow-up period was 18 months. The mean preoperative local kyphosis was 18.7°, and anterior vertebral height loss 51.63%. These significantly improved to 4.58° and 15.67% 1 month after fixation. Three months after implant removal, these radiologic parameters were 5.37° and 16.23%, whereas mean segmental motion was 9.58°. On Denis scale for back pain, 42 patients were P1, with no need for analgesics; 14 patients were P2 with minimal pain; and four were P3, needing occasional use of analgesics.
Conclusion
Satisfactory results can be achieved by posterior spinal fixation without fusion of thoracolumbar burst fractures (A3.2 and A3.3).
