Magnetic resonance imaging and ultrasonography at Eunpyeong St.Mary’s Hospital revealed an ill-defined hypervascular lesion longitudinally oriented in the left erector spinae. The initial differential diagnosis included an inflammatory mass such as proliferative myositis, sarcoidosis, low-grade lymphoma and low-grade infection. The patient underwent ultrasound-guided biopsy with pathology confirming proliferative myositis. Proliferative myositis is a rare benign proliferation of the skeletal muscles that can be mistaken for a malignancy due to its rapid progression.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129609241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prevention, early detection, and proper management of complications are crucial in achieving successful outcomes with MI-TLIF. Patient selection, surgical technique, and postoperative monitoring play key roles. Advances in imaging, tools, and implant design contribute to reducing complications. Surgeons should be aware of the potential complications associated with MI-TLIF and take appropriate measures. Understanding and addressing these complications will lead to better patient outcomes and long-term success.

Methods: Twelve patients who had symptomatic thoracic spinal stenosis with or without co-existing spinal stenosis at other spinal regions were included in the study. The inclusion criteria were complaints of numbness or paresthesia below the affected level, gait difficulties, back pain, hyperreflexia and increased muscle tone upon clinical examination with magnetic resonance imaging evidence of ligamentum flavum thickening resulting in thoracic canal stenosis. The whole spine was evaluated for tandem stenosis. Patients with other causes of thoracic spinal stenosis due to a tumor or malignancy and multiple-level thoracic spinal stenosis were excluded. Results: The patients’ mean age was 59 years. There were 9 men and 3 women. The average duration of symptoms was 8.6 months, and the average follow-up period was 15.4 months. The mean preoperative Nurick score was 3.83 and mean postoperative Nurick score was 1.5. Postop-eratively, 1 patient presented with bilateral lower limb weakness due to local hematoma, which was promptly evacuated with open decompression. Conclusion: MTD allows a magnified surgical field while minimizing disruption to the surrounding soft tissue and bone structures and enables complete decompression of the spinal cord with minimal alteration to the biomechanical strength of the vertebral column. The advantages of tubular decompression include decreased blood loss, reduced hospital stay, early mobilization, and less muscle injury.

Many surgeons perform these cases in stages: first by an anterior/lateral approach for interbody device placement, and second by a posterior approach for fixation. Imaging is typically obtained in between these 2 stages to reassess the surgical anatomy. We evaluated the utility of interstage imaging by comparing alignment parameters between baseline, interstage, and final postoperative radiographs. Methods: We reviewed MIS deformity cases performed at our institution by 3 expert surgeons, which were staged and had complete preoperative, interstage, and postoperative radiographs. Standard alignment parameters at all timepoints were compared. Results: Thirty-three patients met the criteria for inclusion. There were significant differences between baseline and interstage values for lumbar lordosis (LL, p=0.004), pelvic tilt (PT, p=0.002), and pelvic incidence-lumbar lordosis mismatch (PI-LL, p=0.002). No significant differences existed between interstage and postoperative measurements for these sagittal parameters. Significant differences were found between interstage and postoperative values for the major Cobb angle (p=0.012) and the lumbar Cobb angle (p=0.016). Conclusions: In staged cases, our surgeons typically obtain interstage imaging, primarily standing scoliosis films. These studies inform the final levels of instrumentation and the need for additional posterior osteotomies/decompression during stage II. Based on interstage imaging findings, most sagittal correction occurs after stage I, while coronal correction occurs after stage II.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128253966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhancements in microsurgery, tubular retractor, endoscopy, and various percutaneous techniques, as well as improvement of implant materials, have proven to be milestones. The specialty of spine surgery has seen groundbreaking progress over the years, with endoscopic spine surgery (ESS) and minimally invasive surgery (MIS) using tubular retractor playing a pivotal role in this evolution [1-3]. Yet, as is the case with any surgical procedure, ESS is not without its challenges. This special issue, \"The complications and essential surgical techniques in minimally invasive spine surgery and endoscopic spine surgery,\" delves into the depth of these challenges, providing comprehensive insight into the realm of minimally invasive spine surgery and ESS.

Methods: This study analyzed all patients with the classic features of POS e who underwent index surgery elsewhere and presented to us. They had not responded to conservative care for 3 weeks and were operated further with open TLIF. The treatment response was judged by the declining values of inflammatory markers, improvements in mobility, and decreases in pain. Patients’ outcomes were analyzed using a visual analogue scale (VAS), the Oswestry Disability Index (ODI), and the occurrence of complications. Radiological outcomes were assessed by fusion and implant stability. The spectrum of the demographic presentation was analyzed. PubMed was searched to find the incidence of POS e and the spectrum of organisms involved. Results: Fifteen patients were operated primarily by interventionalists and four by surgeons among 19 POS e patients who finally underwent TLIF at Stavya Spine Hospital & Research Institute. Organism culture positivity was found in 10 and no culture results were present in 9 cases. All TLIF cases had a follow-up of 52.94±13.66 months (range, 28–71 months). The preoperative back pain VAS improved from 9.47±0.61 (8–10) to 0.42±0.50 (0–1). The leg pain VAS improved from 5.78±4.19 (6–10) to 0.52±0.61 (0–1). The preoperative ODI improved from 87.01±7.70 (73.33–97.79) to 7.36±8.14 (0–26.67). No major complications occurred. Cure of infection and stable reconstruction with fusion were achieved in all patients. Conclusion: POS e has a very low reported incidence. Standardization of training and sterilization would further reduce its incidence. However, aggressive early TLIF in patients with nonresponding POS e produces beneficial results.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124720296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated differences in bone healing at the postoperative laminecrtomy site between 2 surgical treatments performed in different environments. Methods: From January 2018 to June 2021, 66 patients who underwent laminectomy at Department of Neurosurgery, Gangnam Severance Hospital were retrospectively reviewed. All patients were matched for sex, age, body mass index, bone mineral density, and follow-up duration at a 1:2 matching ratio and were divided into the UBE group (22 patients) and the microscopic discectomy group (44 patients). We investigated the site of laminectomy shown on pre-operative and postoperative x-ray images using ImageJ software. The factors related to bone healing were also investigated. Results: The average bone healing area was 69.59 mm 2 in the UBE group and 44.56 mm 2 in the microscopic discectomy group, constituting a significant difference (p=0.022). The remaining laminectomy area was significantly lower in the UBE group than in the microscopic discectomy group (13.91 mm 2 vs. 53.84 mm 2 , p<0.001). The bone recovery ratio in the UBE group was 85.42%, compared to 51.33% in the microscopic discectomy group, which was a significant difference (p<0.001). The primary laminectomy area, bone healing during 6 months, and clinical outcomes were not significantly different between the 2 groups. Conclusion: Compared with the microscopic discectomy group, the UBE group had a larger bone healing area and a higher bone recovery ratio for patients with lumbar discectomy. These findings suggest that preserving normal structures is more feasible during UBE than during microscopic surgery.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134041970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the outcomes of ACDF are quite satisfactory, recurrent radiculopathy due to restenosis or adjacent degeneration cannot be completely avoided. We applied posterior endoscopic cervical foraminotomy (PECF) as salvage surgery after ACDF in 11 patients (16 levels). Methods: We performed PECF in 11 patients (16 levels) in the past 5 years for recurrent radiculopathy after ACDF. The time until the development of recurrent radiculopathy ranged from 8 months to 3 years. Before surgery, all patients were treated with adequate medication and rehabilitation. The radiological tools used for the evaluation included x-ray examinations (with anteroposterior, lateral, flexion, extension, and bilateral oblique views), computed tomography, and magnetic resonance imaging of the cervical spine. Results: Only one of the 11 patients did not respond immediately; however, that patient showed gradual recovery after decompression surgery in the following 6 months. Another patient showed good sensory function recovery, but transient motor palsy for 2 weeks. Otherwise, all the other patients showed motor or sensory function recovery, without symptom deterioration. None of these patients presented instability or mechanical pain after surgery or required repeat anterior surgery during follow-up (8 to 20 months; mean, 12 months). Conclusion: PECF, a minimally invasive posterior cervical surgical procedure, is efficient and effective as salvage surgery for restenosis after ACDF.
