Abstract
Aim: The aim of this study is to analyze the real-world outcomes of transforaminal epidural steroid injections (TFESIs) in all patients with radiculopathy and their long-term outcomes. Methods: Patients with radiculopathy and failure of conservative treatment were included in a prospective, multicenter, observational cohort study. Results: In total, 117 patients were treated with one or two TFESIs. The mean duration of follow-up was 116 (±14) weeks. In total 19,6% (95% CI: 12.9-28.0%) patients were treated with surgery after insufficient symptom improvement. The evolution to surgery was not associated with etiology, symptom duration or previous spine surgery. Conclusion: Real-world data confirms that TFESIs is an effective treatment with satisfactory results in about 80% of patients for a period of 2 years.

Abstract
BACKGROUND Functional profiling of freshly isolated glioblastoma (GBM) cells is being evaluated as a next-generation method for precision oncology. While promising, its success largely depends on the method to evaluate treatment activity which requires sufficient resolution and specificity. METHODS Here, we describe the 'precision oncology by single-cell profiling using ex vivo readouts of functionality' (PROSPERO) assay to evaluate the intrinsic susceptibility of high-grade brain tumor cells to respond to therapy. Different from other assays, PROSPERO extends beyond life/death screening by rapidly evaluating acute molecular drug responses at single-cell resolution. RESULTS The PROSPERO assay was developed by correlating short-term single-cell molecular signatures using mass cytometry by time-of-flight (CyTOF) to long-term cytotoxicity readouts in representative patient-derived glioblastoma cell cultures (n = 14) that were exposed to radiotherapy and the small-molecule p53/MDM2 inhibitor AMG232. The predictive model was subsequently projected to evaluate drug activity in freshly resected GBM samples from patients (n = 34). Here, PROSPERO revealed an overall limited capacity of tumor cells to respond to therapy, as reflected by the inability to induce key molecular markers upon ex vivo treatment exposure, while retaining proliferative capacity, insights that were validated in patient-derived xenograft (PDX) models. This approach also allowed the investigation of cellular plasticity, which in PDCLs highlighted therapy-induced proneural-to-mesenchymal (PMT) transitions, while in patients' samples this was more heterogeneous. CONCLUSION PROSPERO provides a precise way to evaluate therapy efficacy by measuring molecular drug responses using specific biomarker changes in freshly resected brain tumor samples, in addition to providing key functional insights in cellular behavior, which may ultimately complement standard, clinical biomarker evaluations.

Abstract
BACKGROUND Degenerative diseases of the lumbar spine are often treated with posterior interbody fusion surgery (posterior lumbar interbody fusion [PLIF]) for spinal instability or intractable back pain with neurologic impairment. Several lateral, less invasive procedures have recently been described (lateral lumbar interbody fusion [LLIF]/direct lateral interbody fusion/extreme lateral interbody fusion [XLIF]). The aim of this systematic review is to compare structural and functional outcomes of lateral surgical approaches to PLIF. METHODS We conducted a MEDLINE (PubMed), Web of Science, ScienceDirect, and Cochrane Library search for studies focusing on outcomes and complications comparing LLIF (direct lateral interbody fusion/XLIF) and PLIF. The systematic review was reported using the PRISMA criteria. RESULTS In total, 1000 research articles were identified, of which 5 studies were included comparing the outcomes and complications between the lateral and posterior approach. Three studies found significantly less perioperative blood loss with a lateral approach. Average hospital stay was shorter in populations who underwent the lateral approach compared with PLIF. Functional outcomes (visual analog scale score/Oswestry Disability Index) were similar or better with LLIF. In most of the included studies, complication rates did not differ between the posterior and lateral approach. Most of the neurologic deficits with XLIF/LLIF were temporary and healed completely within 1 year follow-up. CONCLUSIONS A lateral approach (XLIF/LLIF) is a good and safe alternative for PLIF in single-level degenerative lumbar diseases, with comparable functional outcomes, shorter hospital stays, and less blood loss. Future prospective studies are needed to establish the role of lateral minimally invasive approaches in spinal degenerative surgery.

Abstract
BACKGROUND Spondylodiscitis is, after tissue sampling, initially managed with intravenous antibiotics. In patients with treatment failure, surgical debridement and stabilization is considered. An anterior or posterior approach has already been reported as a successful surgical access, but is associated with a large exposure and a significant morbidity. METHODS We present a multicenter Belgian case-series on the use of a minimally invasive extreme lateral interbody fusion procedure with add-on percutaneous pedicle screw fixation for patients with a need for surgical debridement and tissue samples or intractable back pain due to spondylodiscitis. Patient characteristics, microbiology results, antibiotic treatment, pre- and postoperative Visual Analogue Pain Score (VAS) scores, time to bony consolidation, complications and duration of the hospital stay were collected. RESULTS Seven patients with one level spondylodiscitis were included. The mean age 64 years with a mean preoperative VAS score of 8.86 ( ± 0.90). Postoperative VAS score significantly decreased to 2.57 (-70.3%, P < 0.001). Mean antibiotic treatment duration was 8 weeks. Median duration of the hospital stay was 14 days. Patients were followed for 1 year. Complete bony consolidation was observed in 6 out of 7 patients after 1 year. One patient had a stable pseudarthrosis. CONCLUSIONS These results indicate that extreme lateral interbody fusion topped off with a percutaneous pedicle screw fixation might be a feasible, safe and valuable choice to surgically treat patients with spondylodiscitis with fast and important improvement in VAS. Further prospective research might strengthen the sparsely existing literature of minimally invasive surgery for spondylodiscitis to provide the best possible care.

Abstract
Abstract
Glioblastoma remains a highly malignant and intrinsically resistant brain tumor. Despite intensive research through which numerous potential druggable targets were identified, virtually all clinical trials of the past 20 years failed to improve the outcome for the vast majority of GBM patients. However, the identification of small subgroups of patients that showed an exceptional response across several trials, implies that, when selected more carefully, some GBM patients could probably still benefit from these therapies. Identifying these patients requires that suitable biomarkers are identified. In this project, we reassessed the molecular mechanisms of ten actionable compounds (selected from previously failed trials but for which exceptional responders had been observed) in a set of carefully selected patient-derived cell lines that were sensitive/resistant to the selected therapies. Moreover, to deal with tumor heterogeneity, we used a multi-omic functional precision oncology approach, combining scRNA-seq and CyTOF, to identify drug-specific biomarkers by comparing control and treated samples at single-cell resolution. By subsequently correlating the molecular signatures to eventual cytotoxicity profiles, we could identify intrinsically responsive tumor cells at the single-cell level within hours following drug exposure. Overall, this work lays the foundation for an actionable functional diagnostic assay that could help to identify eligible GBM patients in future clinical trials.

Abstract
Obtaining a spine that is well balanced after fusion for scoliotic deformity is primordial for the patients’ quality of life. A simple T-shaped instrument combined with standard intraoperative fluoroscopy can be of great help to evaluate the coronal alignment quickly. The aim of this study was to evaluate if a T-shaped device could predict the postoperative coronal balance. Before finalization of the rod fixation, the balance was checked by verifying the relationship between the T-shaped instrument and the upper instrumented vertebra (UIV), and final adjustments were made to correct the coronal balance. A retrospective study was conducted on 48 patients who underwent surgery to correct scoliotic deformity. Intraoperative and postoperative coronal alignment was measured independently by two observers. The mean intraoperative horizontal offset measured between T-shaped instrument and the center of the UIV was 1,69mm to the right with a standard deviation (SD) of 12,43 mm. On postoperative full spine radiographs, the mean offset between the centra sacral vertical line and the center of the UIV was 2,44mm to the left with a SD of 13,10mm. There is no significant difference in coronal balance between both measurements (p=0,12). With this technique we were able to predict the postoperative coronal balance in all but one patient (97,92%). We conclude that the use of a simple T-shaped instrument can provide adequate intraoperative assessment of coronal balance in correcting scoliotic deformity.

Abstract
Background: A retro-odontoid pannus is often associated with inflammatory diseases. It can also have a noninflammatory cause due to chronic atlantoaxial instability. Case Description: Here, we report a patient with diffuse idiopathic skeletal hyperostosis and a severe noninflammatory retro-odontoid pannus who rapidly improved after posterior craniocervical decompression and arthrodesis. Conclusion: Transoral resection of the pannus, followed by posterior stabilization, is a common treatment for this condition. The pannus can, however, also reduce after posterior stabilization alone (e.g., craniocervical decompression).

Abstract
Background Spinal cord herniation (SCH) is an uncommon cause of myelopathy. Documented trauma is a rare cause, and most cases are idiopathic. One special type of trauma that may lead to SCH is a brachial plexus injury. We report a case of SCH with delayed neurological symptoms after a brachial plexus injury. We reviewed the literature and illustrated the closing technique as described by Batzdorf. Case Description Following a motor vehicle accident, a 27-year-old male sustained a brachial plexus injury and multiple left-sided nerve root avulsions (C6, C7, and C8) resulting into a full paralysis of the left arm. There was also a loss of pain and temperature sensation on the right side of the body. He underwent reconstructive surgery without any functional improvement. After 6 to 7 years his condition worsened. Magnetic resonance imaging revealed a left-sided SCH at the level of C7. He underwent a C6-C7 laminectomy which revealed a pseudomeningocele at C6-C7 accompanied by focal SCH at the location of the C7 root. The SCH was reduced intradurally and the dural defect of the meningocele was covered with a Neuropatch membrane wrapped around the spinal cord (between the spinal cord and the dura) according to the technique described by Batzdorf. Postoperatively, the neurological symptoms improved. Conclusion SCH should be surgically repaired utilizing the technique described by Batzdorf if further neurological deficits develop.

Abstract
OBJECTIVE To investigate the effect of a quality improvement project that resulted in an infection control bundle to reduce the number of spinal cord stimulator (SCS) infections. MATERIALS AND METHODS The study was performed in a single center for neuromodulation from January 1, 2014, through May 31, 2016. In response to a high number of surgical site infections (SSIs) after SCS surgery, a multidisciplinary team analyzed the surgical process and developed an infection prevention bundle consisting of five items: 1) showering and decolonization for five days prior to surgery and showering in the hospital on the morning of surgery; 2) performing the SCS implantation as the first in the daily operating room (OR) program; 3) maintaining a minimal number of people in the OR; 4) providing home care nurses with a folder with SCS wound care instructions including pictures; 5) giving oral specific wound care instructions to patients. The number of infections was calculated for the baseline, implementation, and sustainability phases. RESULTS A total of 410 SCS surgeries were performed during the study period. In the preintervention phase, 26/249 (10.4%) SCS surgeries were infected. During the implementation and sustainability phase, 2/59 (3.4%) and 1/102 (1.0%) SCS surgeries were infected, respectively. The reduction in the number of infections in pre and postintervention phase was statistically significant (p = 0.003). CONCLUSION Multidisciplinary measures to reduce SSIs reduced the number of SCS associated infections in our study setting.

Abstract
INTRODUCTION Arthroscopy has become a major diagnostic tool and treatment option for shoulder pathology. However rare, respiratory complications such as a pneumothorax have been reported in patients undergoing shoulder arthroscopy. Surgery - as well as anesthesiology-related factors and respiratory comorbidity have been hypothesized to intervene in the onset of respiratory complications. CASE REPORT We report the case of a 42-year-old male patient who underwent an arthroscopy of the left shoulder. The anesthesia, the surgical procedure as well as the post-operative course went uncomplicated. The patients were discharged 6 h after the end of the surgical procedure. 4 h after discharge, however, the patient developed severe respiratory distress and signs of hemodynamic shock due to an ipsilateral (tension) post-operative pneumothorax. The available literature is reviewed focusing on the possible pathogenic mechanisms implying the development of this complication. CONCLUSION The presence of a pneumothorax after shoulder arthroscopy is a rare but dangerous complication. It can primarily be attributed to rupture of parietal pleura, rupture of visceral pleura, and alveolar rupture or trauma during anesthesia. In our patient, we speculate that a rupture of parietal pleura was the underlying cause. This can be related to the surgical methodology (portal placement and continuous pump infusion with intermittent suction) and subacromial distention used during the procedure. Awareness, prompt recognition, and treatment are necessary.

Abstract
Neurofibromatosis type-I (NF-I) is an autosomal-dominant hereditary disorder, in which spinal skeletal deformities are one of the manifestations and manifest as acquired abnormalities and present as short, sharp, and angular (usually thoracic) curves. The scoliosis can be severe requiring surgical intervention. The surgical procedure can be difficult because of scalloping of the vertebral bodies and dural ectasia. We state that in selected cases of severe thoracic dystrophic kyphoscoliosis in NF-I, the posterolateral approach is the only possible method to visualize the anterior thoracic spinal cord, perform anterior decompression, and to stabilize the thoracic deformity, because of the anterior dural ectasias and the kyphosis limiting an anterior procedure.

Abstract
We describe three cases of incidentally found lesions in the dural venous sinuses on magnetic resonance imaging, that other had erroneously considered pathological entities. We made the diagnosis of giant arachnoid granulations. The differential diagnosis with thrombosis or intrasinusal tumoral lesions was easily made on the basis of three typical radiological features of the granulations: the hyperintensity of the lesions on FLAIR, a blood vessel within the lesion and bone erosion.

Abstract
BACKGROUND Hemangioblastomas are associated with Von Hippel-Lindau disease (VHLD) in 10-40% of cases. Based upon a literature review we state the core features the neurosurgeon should be aware of. METHODS We performed a selective literature (Cochrane and Medline) search for hemangioblastoma, both sporadic and VHL associated. We reviewed general characteristics (epidemiology, symptomatology, diagnosis, and management) and focused on follow-up as well as screening modalities for sporadic and VHL associated lesions. RESULTS Based upon our literature search, we established guidelines for screening and follow-up in both sporadic and VHL associated hemangioblastoma patients. CONCLUSIONS Screening for retinal angiomas, abdominal masses, and pheochromocytomas as well as genetic analysis is recommended for every patient with a newly diagnosed hemangioblastoma. Follow-up is by magnetic resonance imaging (MRI) of the clinical neuronal region at 6 and at 12-24 months postoperatively. For VHL-associated hemangioblastomas yearly investigation for craniospinal hemangioblastoma by MRI and yearly screening and follow-up for retinal angiomas is recommended. Annual abdominal ultrasound with triennial computed tomography (CT) imaging for abdominal masses is postulated. Annual audiometry is to be performed for possible endolymphatic sac tumor, detailed radiographic imaging of the skull base should be performed upon abnormality in auditory testing. Investigations for cystadenomas of the epidydimis and broad ligament only are mandatory on indication. Annual investigation for pheochromocytoma is recommended.
