title: Minimally invasive solid long segmental fixation combined with direct decompression in patients with spinal metastatic disease.
abstract: This study seeks to discuss the efficiency of minimally invasive surgery of posterior long segmental fixation plus direct decompression in patients with spinal metastatic tumors. Twenty-five patients received minimally invasive surgery of long segmental fixation combined with direct decompression from posterior approach. Pain and neurologic improvement in these patients pre- and post operation were evaluated by Denis' Pain Scale and Frankel Score, respectively. Seventeen patients (68.0%) showed significant decreases in Denis' Pain score after surgery (p < 0.0001). Paralysis symptoms were improved in nineteen patients (76.0%). The Frankel Score exhibited significant difference between pre-operation and post-operation (p < 0.0001). Operation time and blood loss in this cohort were 324 ± 90 min and 1047 ± 730 ml, respectively. No fatal complications were observed as a result of surgery. In conclusion, minimally invasive surgery of posterior long segmental fixation combined with direct decompression is a safe and efficient strategy to release pain and improve neurological function in patients with spinal metastatic tumors.
