Postoperative Spinal Subdural Lesions Following Lumbar Spine Surgery: Prevalence and Risk Factors.

Postoperative Spinal Subdural Lesions Following Lumbar Spine Surgery: Prevalence and Risk Factors. Asian Spine J. 2017 Oct;11(5):793-803 Authors: Nagamoto Y, Takenaka S, Aono H Abstract Study Design: Retrospective case-control study. Purpose: To clarify the prevalence and risk factors for spinal subdural lesions (SSDLs) following lumbar spine surgery. Overview of Literature: Because SSDLs, including arachnoid cyst and subdural hematoma, that develop following spinal surgery are seldom symptomatic and require reoperation, there are few reports on these pathologies. No study has addressed the prevalence and risk factors for SSDLs following lumbar spine surgery. Methods: We conducted a retrospective analysis of the magnetic resonance (MR) images and medical records of 410 patients who underwent lumbar decompression surgery with or without instrumented fusion for degenerative disorders. SSDLs were classified into three grades: grade 0, no obvious lesion; grade 1, cystic lesion; and grade 2, lesions other than a cyst. Grading was based on the examination of preoperative and postoperative MR images. The prevalence of SSDLs per grade was calculated and risk factors were evaluated using multivariate logistic regression analysis. Results: Postoperative SSDLs were identified in 123 patients (30.0%), with 50 (12.2%) and 73 (17.8%) patients being classified with grade 1 and 2 SSDLs, respectively. Among these, one patient was symptomatic, requiring hem...

In this report, we present a patient with a complex L3 burst fracture from a remote trauma s/p stabilization. Thirty-two years later, he developed progressive neck pain, upper extremity radiculopathy, dysesthesias, and clinical myelopathy (dropping objects, gait imbalance). An MRI demonstrated an expansile syrinx from C2-conus medullaris which previously had been unsuccessfully treated by fenestration. We offered a T1–2 laminectomy and placement of synringosubarachnoid shunt. In the associated video (Supplemental Digital Content 1,, we demonstrate the step-by-step approach for thi...

Laminoplasty is a common surgical method used to treat patients with cervical ossification of the posterior longitudinal ligament (OPLL). Although laminoplasty is preferred over traditional laminectomy, the factors affecting the complications and outcomes are unclear. Recently, sagittal balance indexes have been revealed to be predictors of clinical outcomes in patients with cervical degenerative diseases, but their relationships with laminoplasty-treated OPLL outcomes remains unknown.

Study Design. Retrospective review. Objective. Compare postoperative infection rates and 30-day outcomes in spine surgery patients with and without a preoperative urinary tract infection (UTI). Summary of Background Data. There is mixed evidence regarding safety and risks when operating on spine patients with a preoperative UTI. Methods. Using data from the American College of Surgeons National Surgical Quality Improvement Program, we identified all adult patients undergoing spine surgery between 2012 and 2017 with a preoperative UTI. Patients with other preoperative infections were excluded. Our primary outcome...

We describe the use of high-frequency SCS to alleviate the patient's post-laminectomy pain as well as his abdominal pain. Our case describes SCS use with multi-level lead placement targeting both post-laminectomy pain and abdominal pain. We describe a strategy that can be useful to patients with concurrent pain from more than one source. Our case also adds to the growing evidence supporting the use of SCS for treating chronic visceral pain syndromes. PMID: 32431535 [PubMed]

Surgery for degenerative lumbar disease such as lumbar laminectomy and discectomy are among the most common procedures performed in the United States (US). The incidence of laminectomies in the US increased by 11.3% over a 10-year period from 1998 to 2008 [1]. Similarly, the incidence of lumbar fusion surgery has increased by 55% from 2005-2014 [2]. Lumbar fusion alone experienced a 3.3-fold increase in cost compared with the 2.3-fold increase in cost associated with joint replacement, resulting in a $33.9 billion national expense in 2008 [1].

In this study the authors aimed to evaluate the neuroprotective effects of ozone and their possible roles in recovery from spine injury, assessed based on biochemical, histological, and neurological parameters using an experimental spine injury model in rats. METHODS: The study included 31 female Wistar albino rats. The rats were divided randomly into 5 groups, with 7 rats in each group except the sham group, which contained 3 rats, as follows: group 1 (sham), laminectomy; group 2 (control), laminectomy and spinal trauma with no medical treatment (0.5 ml isotonic saline applied 1 hour postsurgery); group 3, single med...

Authors: Torres H, Rivera M, Garcia L, Altieri G Abstract Presented herein is the case of a 37-year-old male who was scheduled for an anterior decompressive laminectomy after suffering trauma to the cervical area (C6-C7). An intraoperative acute pulmonary embolism (APE) was suspected after persistent hypoxemia and a decreased end-tidal CO2 that was refractory to proper management. After 6 intraoperative episodes of cardiac arrest that followed, intravenous alteplase (thrombolytic therapy) was administered, and the patient was stabilized without major complications. Eventually, APE was successfully diagnosed and tre...

CONCLUSIONS: The above results indicate that mocetinostat inhibits HDAC1 expression and decreases the conduction of the AKT/GSK3b pathway in fibroblasts, leading to myofibroblast activation and apoptosis elevation. Hence, mocetinostat ameliorates epidural fibrosis. PMID: 32373984 [PubMed - in process]

Conclusion: Patients with cervical spondylotic myelopathy undergoing laminoplasty (25 patients) showed better 12-month postoperative outcomes (JOA scores and Nurick grades) versus those having laminectomies (39 patients). PMID: 32363068 [PubMed]
