Event Description
Citation: https://doi.Org/10.1016/j.Jos.2022.10.026 summary: background: there is little information on outcomes for spinal cord tumor treated surgically with instrumentation.Analysis of surgical outcomes and complications in such cases is needed to develop generalizable conclusions and to help inform patients.Methods: the subjects were 41 patients treated with instrumentation surgery for dumbbell type tumor resection.Demographic data; tumor histology, level, and location; number of fused vertebra; use of a bilateral or hemilateral screw; operative time; ebl; tcmep monitoring; lumbar subarachnoid drainage; duration of subfascial drainage; postoperative motor and sensory deficits; csf leakage, implant-related complications; time for union of fused vertebra; salvage surgeries, and pre-/postoperative mccormick scale were obtained from medical records.Significant factors related to postoperative motor deficits were identified.Results: postoperative motor deficit occurred in 9 cases (22.0%) and all recovered in 30 days after surgery.Csf leakage at 7 days and 2 years after surgery was subfascial (n ¼ 31, n ¼ 6) and subcutaneous (n ¼ 3, n ¼ 4).Cases with postoperative motor deficits more commonly had lower cervical lesions; those with csf leakage had longer operative times; and those with delayed union had more use of hemilateral instrumentation.Conclusion: in this study in 41 spinal cord tumors treated surgically with instrumentation, the rate of postoperative motor deterioration was 22.0%, and csf leakage was found in 17.1%.Reported event(s): this article documents the procedures for 41 patients that presented with cervical or lumbar tumors.21 of the patients were male and 20 were female, with a mean age of 46.8 years.Postoperative motor deficit occurred in 9 cases, and all recovered in 30 days after surgery.The motor deficits included c5 palsy (n ¼ 3), c6 palsy (n ¼ 1), c7 palsy (n ¼ 2), c8 palsy (n ¼ 1), l4 palsy (n ¼ 1), and muscle weakness in the distal lower extremities originating in the conus medullaris.Subfascial and subcutaneous cerebrospinal fluid (csf) leakage was found in 31 and 6 cases at 7 days after surgery, and in 3 and 4 cases at 2-year follow-up.Implant-related complications occurred in 1 cases (adjacent disease).
