However, it is exclusive for adults who previously had normal spinal alignment. Such pathology with no specific etiology results from a combination of degenerative lumbar diseases. Oblique lumbar interbody fusion (OLIF) is one of the fusion techniques used. It was introduced to overcome the disadvantages of the commonly used interbody fusions like anterior (ALIF), lateral (LLIF), or posterior (PLIF) interbody fusions. OLIF can achieve spinal stability, correct alignment in coronal and sagittal balance anteriorly, and indirectly decompress neural structures with fewer complications related to traditional transpsoas or retropsoas approaches. Study Design: Prospective clinical case study. Objective: To assess the degree of coronal and sagittal deformity correction in patients suffering from degenerative lumbar spine deformities after stand-alone (SA) OLIF. Patients and Methods: Patients with ADS following specific inclusion criteria underwent SA OLIF. Preand postoperative clinical data (back and leg pain VAS and ODI), radiological data (spinopelvic parameters, segmental Cobb’s angle, and anterior disc height), and intraoperative data (operative time, amount of blood loss, “intraoperative or postoperative” complications, and hospital stay) were all analyzed and compared statistically. Results: A total of 28 patients and 30 levels underwent operation by SA OLIF, with a mean age of 50.54 ± 6.05 years, including 14 males and 14 females. The mean operative time/min, blood loss/ml, and hospital stay/day was 91.29 ± 14.23, 195.54 ± 42.299, and 2.78 ± 0.875, respectively.

Purpose : We present a case report of multiple noncontiguous spontaneous spondylodiscitis caused by E. coli involving the cervical and lumbar spine following a mastectomy for breast cancer. We will explain the difficulties in diagnosis, treatment, and follow-up with the concomitant. Study Design: A case report and literature review. Case Report: A middle-aged patient with a history of breast carcinoma underwent surgery. Two weeks after mastectomy, the patient developed severe cervical and lumbar spine pain and a low-grade fever (37.5– 38.3 °C). Moreover, neurological examination revealed a right-sided antalgic gait, right-sided weakness, and a positive straight leg raising test. Upon presentation, elevated C-reactive protein (CRP) and white blood cells (WBC) were noted. Magnetic resonance imaging (MRI) showed consistent spondylodiscitis at C5-C6 and L3-L4 levels with stenotic features at L4-L5 levels. Surgical treatment of the lumbar region via posterior spinal instrumentation from L3 to L5 levels and decompression was done with a biopsy. Erythrocyte sedimentation rate (ESR) CRP titers were also performed for the follow-up plan, which showed a reduction in 3, 6, and 12 weeks postoperatively. Conservative treatment of the cervical region was undertaken with a complete cure. Conclusion: Multiple noncontiguous spondylodiscitis after nonspinal surgery is a relatively rare complication requiring a high suspicion index. Surgery is recommended in case of failure of conservative measures, neurological deficit, or mechanical instability as in this case. Furthermore, both clinical examination and blood tests should be used to assess the treatment outcomes.

Purpose: This study determines the frequency and risk factors for cranial FJV during pedicle screw instrumentation in various lumbar spine disorders. Study Design: A retrospective study. Patients and Methods: The data and imaging of adult patients with pedicle screw instrumentation for lumbar disorders from June 2018 to June 2021 were retrospectively reviewed for cranial FJV rate and evaluated for the role of the technique of instrumentation (conventional open or percutaneous), the facet angle (FA), the lumbar level, and the type of the disorder as risk factors for this violation. Preoperative Magnetic Resonance Imaging (MRI) was reviewed to measure the FA using T2 axial images. Postoperative Computed Tomography (CT) scans were examined to determine and grade cranial FJV. Results: The study included 360 patients. The overall FJV rate was 17.6%. The FJV rate significantly increased among the percutaneous fixation group compared to that of the open one (29.2% vs. 15.9%, respectively, p = 0.001). Patients with FJV had significantly larger FAs (p < 0.001). Moreover, patients with significantly larger FAs had higher grades of FJV (p value < 0.001). The FJV rate significantly increased with FAs > 40.12° (p < 0.001). L5 level and degenerative disease were more prone to FJV and higher grades of violation. Conclusion: The method of fixation, FA, lumbar level, and the type of lumbar disorder were the independent predictors of cranial FJV. This study reported a higher rate of FJV among patients with percutaneous fixation. The larger the FA, the higher the FJV rate and grade, especially with FAs > 40.12°, L5 level, and degenerative disease.

Purpose: To compare the radiologic and clinical outcomes between SC and CCP in ACDF for the treatment of CSM. Study Design: Ambispective clinical case study. Patients and Methods: The patients who underwent ACDF for CSM using SC or CCP between January 2014 and December 2018 were included in the study. Forty-six patients out of 230 eligible patients were included in the study. Twenty-six patients underwent CCP, while 20 underwent SC. They were subjected to detailed neurologic and radiologic examination. Neurologic outcome was measured using the Nurick and mJOA scores and dysphagia using the Bazaz score. Fusion was assessed by the presence of bridging trabeculae and absence of movement between the spinous processes of the fused segments with lordosis by Cobbs’ angle. We also reported cage subsidence, adjacent segment degeneration (ASD), and implant complications. Results: Mean follow-up was for four years. The most common level operated was C5/C6. Neurologic status improved significantly in both groups following surgery. The rate of dysphagia was not different between the groups. Fusion was achieved in 92.3% of the CCP group and 90% of the SC group (p > 0.05). The rate of subsidence was higher in the SC group (p = .026).

It is a benign health problem, but it develops slowly in nature. Purpose: To review the available data about degenerative scoliosis in adults and the recent concepts and treatment options. Study Design: A narrative literature review. Patients and Methods: The author reviewed the English literature published through the last two decades for recent and relevant data about the pathogenesis, presentation, and management of adult degenerative scoliosis. A PubMed search was conducted using both phrase searching and combined searching using Boolean operators. The most relevant articles according to the study aim and spine surgeon’s practice were extracted. Results: Adult degenerative scoliosis is a triplanar deformity affecting coronal and sagittal parameters and axial spinal dimensions. The condition starts with age-related disc degeneration and progresses slowly over the years with worsening back pain and neurological deficits in advanced stages. Selected stable patients with early deformities can be managed nonsurgically through various pharmacological, physical, and interventional measures. However, most cases with degenerative scoliosis are best treated surgically via various open or minimally invasive procedures, reserving the conservative measures for nonsurgical candidates or as preoperative palliation. Conclusion: Adult degenerative scoliosis is best managed by a multidisciplinary team of neurosurgeons and orthopedic surgeons in a patient-specific manner. Further studies are required for comparing and identifying the best surgical strategies in a patient-specific approach.

Purpose: This article investigates the safety and the efficacy of unilateral endoscopic decompression for patients with monosegmental degenerative lumbar spinal canal stenosis (LCS). Study Design: Prospective clinical case series. Patients and Methods: Thirty consecutive patients with degenerative LCS were treated with endoscopic laminotomy with medial facetectomy. Patients were treated with the EasyGO! 2nd Generation system (Karl Storz, Tuttlingen, Germany) at our institutions between March 2018 and September 2020. Primary outcomes parameters included the Numerical Pain Rating Scale (NPRS) and Oswestry Disability Index (ODI) to quantify pain and disability, respectively. The length of the incision, the duration of surgery, the operative blood loss, and the duration of hospital stay were calculated. The mean follow-up period for patients was 10.5 ± 2.3 (range, 6–12) months. Results: The mean age was 56.5 ± 5.7 years. All thirty patients had neurogenic claudication. 63% of the patients had bilateral leg pain, 37% had unilateral leg pain, and 66% had low back pain. Seven patients (23%) had motor weakness preoperatively. The spinal segments affected were as follows: L4-L5 in 22 cases; L3-L4 in 6 cases; L2-L3, one case; L5-S1, one case. There was a statistically significant reduction in the mean values of NPRS for both leg and back pain in the follow-up period (P < 0.001). Moreover, the ODI mean value was statistically significantly reduced in the follow-up period (P < 0.001). the mean operative blood loss was 147.2 ± 68.3 ml, the mean operative time was 134.7 ± 28.34 minutes, and the mean hospital stay was 1.4 ± 0.8 days.

Ependymomas usually grow slowly, compressing rather than infiltrating spinal tumors. Among different prognostic and predictor factors, the extent of resection has been the strongest predictor of outcomes. Multimodal intraoperative neurophysiological monitoring (IONM) helps maximize the extent of resection with minimal postoperative neurological complications. Purpose: To assess the impact of IONM on the extent of surgical resection and outcomes of spinal cord ependymomas. Study Design: A retrospective cohort study. Patients and Methods: Twenty-five patients who underwent spinal cord ependymoma resection in 4 centers between March 2014 and February 2018 were eligible for the inclusion criteria of this study. Patients were divided into two groups: the IONM group and the non-IONM group. IONM consisted of electromyography (EMG), transcranial motor evoked potentials (tcMEP), and somatosensory evoked potentials (SSEP). All patients were submitted for full neurological examination and MRI of the spine both preoperatively and at the postoperative routine follow-up. Postoperative radiotherapy was conducted routinely by our radiotherapists. The secondary outcomes were the correlation between the warning criteria of IONM and postoperative neurological outcomes and their impact on the extent of tumor resection. Also, a recurrence rate during the follow-up period was reported.
