BackgroundThe silastic tube technique, in which a chest tube is placed into the vertebral body defect and impregnated with polymethyl methacrylate, showed good results in patients with lumbar and thoracic neoplastic diseases. There has been only 1 study about the effectiveness and safety of this technique in patients with cervical metastases. We aimed to report our experience in using this technique to reconstruct the spine after corpectomy for cervical metastasis.MethodsAll patients with cervical spinal metastasis who underwent surgical treatment using a chest tube impregnated with polymethyl methacrylate in conjunction with anterior cervical plate stabilization were retrospectively recruited. Demographics, tumor histology, revised Tokuhashi score, preoperative and postoperative American Spinal Injury Association score, preoperative and postoperative ambulatory status, perioperative complications, and survival time were collected.ResultsThis study included 16 patients. The most common primary tumor site was the lung (6 patients; 37.5%). The mean (SD) survival time was 408 (795) days (range, 1-2797 days), and the median survival time was 72 days (95% confidence interval 28-116 days). Four patients (25%) died within 30 postoperative days. There was no surgical site infection or instrument failure after the surgery. Five patients (31.2%) lived >180 days, and 3 patients (18.8%) lived >360 days. One patient (6.2%) was still alive at the end of the study.ConclusionsThe silastic tube technique in conjunction with anterior cervical plate stabilization might be safe, effective, and cost-effective for patients with cervical spine metastasis.Copyright © 2021 Elsevier Inc.
