Incidence and Risk Factors for Late Neurologic Deterioration after C3-C6 Laminoplasty for Cervical Spondylotic Myelopathy.
Study Design Retrospective study. Objective We previously reported that the long-term neurologic outcomes of C3-C6 laminoplasty for cervical spondylotic myelopathy (CSM) are satisfactory, with reduced frequencies of postoperative axial neck pain and kyphotic deformity. However, only 20 patients were included, which is a limitation in that study. ⋯ On the other hand, in 134 patients without LND (non-LND group), the mean JOA score significantly improved from 10.2 before surgery to 13.4 at the time of maximum recovery and was maintained by the final follow-up (13.2). Compared with the non-LND group, the LND group showed significantly smaller anteroposterior spinal canal diameter at C7, more restricted postoperative C3-C6 ROM, and greater postoperative decrease in disk height at C6-C7, although a logistic regression analysis showed no significant differences. Conclusions In patients with CSM with more severe developmental spinal canal stenosis at C7, accelerated degeneration at the caudal segment resulting from restricted C3-C6 ROM after C3-C6 laminoplasty might lead to LND.

Surgical Outcomes in Patients with High Spinal Instability Neoplasm Score Secondary to Spinal Giant Cell Tumors.
Study Design Retrospective review. Objective To describe the surgical outcomes in patients with high preoperative Spinal Instability Neoplastic Score (SINS) secondary to spinal giant cell tumors (GCT) and evaluate the impact of en bloc versus intralesional resection and preoperative embolization on postoperative outcomes. Methods A retrospective analysis was performed on 14 patients with GCTs of the spine who underwent surgical treatment prior to the use of denosumab. ⋯ Conclusions Surgical excision of spinal GCTs causing significant instability, assessed by SINS, is associated with high intraoperative blood loss despite embolization and independent of resection method. En bloc resection requires a longer operative duration and is associated with a higher risk of complications when compared with intralesional resection. However, the increased morbidity associated with en bloc resection may be justified as it may minimize the risk of local recurrence.

Delayed Onset of Subdural Hematoma following Epidural Catheter Breakage.
Study Design Case report. Objectives To describe a case of delayed-onset spinal hematoma following the breakage of a spinal epidural catheter. Methods The authors describe the clinical case review. ⋯ Generally, when the breakage of an epidural catheter occurs without symptoms, follow-up alone is recommended. However, because spinal hematoma might exhibit a late onset, the possibility of this complication should be considered when deciding whether to remove the catheter fragment. We believe that in our patient, there could be a relationship between the catheter fragment and subdural hematoma, and catheter breakage could have been a risk factor for the spinal hematoma.

ReviewThe Outcome of Using Closed Suction Wound Drains in Patients Undergoing Lumbar Spine Surgery: A Systematic Review.
Study Design Systematic review. Objective Determine whether closed suction wound drains decrease the incidence of postoperative complications compared with no drain use in patients undergoing spine surgery for lumbar degenerative conditions. Methods Electronic databases and reference lists of key articles were searched up through January 22, 2015, to identify studies comparing the use of closed suction wound drains with no drains in spine surgery for lumbar degenerative conditions. ⋯ The overall strength of evidence for these findings is considered low or insufficient. Conclusions Conclusions from this systematic review are limited by the quality of included studies that assessed the use of closed suction wound drains in lumbar spine surgeries for degenerative conditions. We believe that spine surgeons should not routinely rely on closed suction wound drains in lumbar spine surgery until a higher level of evidence becomes available to support its use.

Case ReportsRemote Cerebellar Hemorrhage after Revision Lumbar Spine Surgery.
Study Design Case report. Objective To report a case of remote cerebellar hemorrhage (RCH) without intraoperative dural tear after revision lumbar spine surgery. RCH is a rare postoperative complication following spine surgery. ⋯ At 1-year follow-up, the patient continued to have no neurologic sequelae. Conclusion This report demonstrates that RCH can occur without intraoperative dural tear. Although rare, any patient with new onset of declining neurologic symptoms following spine surgery should have a brain MRI and should have RCH on the differential diagnosis.
