To evaluate the safety and efficacy of the far-lateral approach in the resection of ventral and ventrolateral upper cervical meningiomas. Overview of Literature: Upper cervical meningiomas are a common disease entity. These lesions can be surgically treated via many accesses. The far-lateral approach is a very appealing technique for these lesions. Methods: We assessed 23 patients with a mean age of 57.3±15 years. According to the Japanese Orthopedic Association (JOA) scale; eight patients had grade 0, nine had grade I, and six had grade II. All patients underwent plain radiography and magnetic resonance imaging of the cervical spine. The foramen magnum was involved in 10 patients, C1-2 in seven, C2-3 in four, and C3-4 in two. All patients were operated via the far-lateral approach. Results: Gross total resection was achieved in 21 patients. Sixteen lesions were psammomatous, five were fibroblastic, and two were meningothelial meningiomas. The mean operative duration was 135±40 minutes, while the mean operative blood loss was 450±210 mL, and the mean hospital stay was 4.3±2.2 days. At the final follow-up that was conducted at 27.6±21 months and as per the JOA score; 16 patients were classified into grade 0 and 7 into grade II. The condition of none of our patients deteriorated postoperatively. There was no significant correlation of the clinical outcome with tumor level, pathological subtype of the tumor, symptom duration, age, and sex. There was no significant correlation of tumor resection completeness with tumor level, tumor pathological subtype, or tumor topography (ventral or ventrolateral). Conclusions: The far-lateral approach is a safe and effective access for ventral and ventrolateral cervical meningiomas. It allows direct access to tumor with no spinal cord or nerve roots traction, and thus may yield a fairly better outcome than the standard posterior approach.

Background data: The degenerative lumbar diseases form a burden on both the patients and the society. The development of the degenerative process is highly linked to the aging process as discussed by Kirkandly Willis where the degenerative spine passes through 3 phases of process that results in the degenerative diseases. The management of the degenerative spine deformities varies and depends on various factors. Traditional surgical management involves instrumentation, decompression and fusion processes. Oblique Lumbar interbody fusion ‘OLIF’ is a novel technique when used alone as in stand-alone OLIF ‘SA-OLIF’ it could achieve degenerative deformity correction along with neural decompression, however, the final aim of SA OLIF where solid fusion is required still is under evaluation and literature lacks the essential data for this approach. This study aims to assess the fusion of the SA-OLIF in the management of degenerative lumbar scoliosis. Study Design: A Prospective clinical case study. Objective: To assess the fusion rates in patients suffering from degenerative lumbar scoliosis ADS after SA-OLIF. Patients and Methods: Patients with ADS following a specific inclusion criterion underwent SA OLIF. Pre-, and Post-operative clinical data; back and leg pain ‘VAS score’ and ODI, radiological data; for fusion assessment. Intra-operative data: operative time, amount of blood loss, complications ‘intra-operative or post-operative’ and hospital stay were all analyzed and compared statistically. Results: A total of 28 patients and 30 levels were operated by SA OLIF, with mean age 50.54±6.05 included 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. The mean of Back Pain ‘VAS’, The mean of Leg Pain ’VAS’ and ODI changed from pre-operatively 7.36±0.98, 6.36±0.911and 68.615±8.72 to 4.07±1.01, 2.07±0.9 and 20.23±4.7 in 1-year respectively. In this study we had 92.9% fusion rates after 1-year. Operative complications occurred in 3 cases with segmental artery injury. Post-operative complications were 1 cage dislodgment immediately post-operative and 2 cases of cage subsidence after 1-year. Conclusion: SA OLIF can result in high rates of fusion. There are multiple factors that determine the rate of fusion such as the quality of the vertebrae and endplate preservation during the preparation procedure.

Background Data: Adult degenerative scoliosis has at its starting point the same broader definition of adult scoliosis, which is defined as a Cobb angle of greater than 10 degrees measured in the coronal plane. 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. Pre-and 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.
