흉요추부 골절의 수술적 치료 후 척추경 기기제거술의 효용성

INTRODUCTION: Removal of posterior spinal implants after a successful spinal fusion is a common procedure in thoracolumbar fractures. However, there are still ongoing controversies regarding the advantages and drawbacks of the implant removal. We aimed to investigate the clinical and radiologic outcomes concerning the implant removal after fusion in thoracolumbar fractures. MATERIALS AND METHODS: Thirty-three patients had undergone an implant removal surgery after a posterior fusion with pedicle screw fixation for thoracolumbar fractures. The mean duration after the index surgery was 25.3±17.6 months. A control cohort of 38 consecutive patients with thoracolumbar fractures that had pedicle screw implants was enrolled. Subjects were followed for more than two years, with clinical parameters (VAS and ODI) and radiologic parameters (vertebral compression ratio and segmental angle) documented during follow up. RESULTS: Demographic variables regarding age, gender, level and type of fracture, radiologic parameters, and compensation status at the index surgery were homogeneous between the two groups. Clinical and radiologic outcomes at the time of removal surgery in the removal group were similar with those of the control group. After 4-year follow-up from the index surgery, radiologic parameters were not different between the two groups. VAS was significantly lower in the removal group (2.9±1.5) than the control group (3.8±1.5) (P=0.028). ODI was also lower in removal group (13.8±8.1) than control group (18.5±11.0)(P=0.042). DISCUSSION: Removal of implant after a successful spinal fusion alleviated pain and disability in patients with thoracolumbar fractures. Further investigation regarding the implant-related pain is needed.
