Circumferential resection decompression combined with bone cement fill-separation for treatment of spine meta-static tumor / 局解手术学杂志

ABSTRACT

Objective To explore the effect of spinal 360°circumferential resection decompression combined with bone cement fill-separation and pedicle screw fixation instrumentationb for patients suffering from spinal metastases.Methods Retrospectively analyzed the clinical data of 42 patients suffering from spinal metastases and underwent spinal 360°circumferential resection decompression combine with bone cement fill-separation and pedicle screw fixation instrumentation in our hospital from April 2012 to October 2016.The pain level were assessed by visual analogue scale(VAS),the functional impairment was classified by Karnofsky score(KPS) and the neurologic deficit was evaluated by Frankel grade before preoperation,1 week after operation and 3 months after operation.Results Through the following-up of 3 months,there was no neural symptoms relapse in primary segment.The VAS score was (0.57 ±0.79) points,and the KPS was (72.61 ± 19.12) points 3 months after operation,which were significantly improved compared with the data before operation (P ＜ 0.05).The VAS score improvement rate was (91.09％ ±13.73％),and the Frankel grade improvement rate was 80％.Conclusion Circumferential resection decompression combined with bone cement fill-separation and pedicle screw fixation instrumentationb for patients suffering from spinal metastases can effectively improve the neural symptoms and life-quality of patients and prevent neural symptoms relapsing in primary segment after operation.
