Foraminal decompression using a minimally invasive technique to preserve facet joint stability and function without fusion reportedly improves the radicular symptoms in approximately 80% of patients and is considered one of the good surgical treatment choices for lumbar foraminal or extraforaminal stenosis. However, proper decompression was not possible because of the inability to access the foramen at the L5-S1 level due to prominence of the iliac crest. To overcome this challenge, endoscopy-based minimally invasive spine surgery has recently gained attention...

There is little evidence regarding the optimal approach to treatment for delayed-onset lumbar radiculopathy due to foraminal stenosis after osteoporotic vertebral fracture. Here, we describe the use of spinal endoscopy for the treatment of this disabling condition, in an 80-year-old woman presenting with severe radicular pain following an osteoporotic lumbar compression fracture. Radiographic findings showed the compression of the L2 root within the foramen, and computed tomography identified a fragment of the posterior wall of the vertebral body under the pedicle...

BACKGROUND: Endoscopy has replaced open surgery, especially in spinal surgery. Among them, image-guided epiduroscopy allows pain generators to be identified, including epidural adhesion, fibrotic tissues, root compression, and spinal stenosis. However, the heavy lead apron worn by pain physicians to avoid exposure to radiation can induce occupational hazards, such as orthopedic complications and radiation-induced cancer. Hence, we developed a robotic system to address these problems. OBJECTIVE: The aim of the study was to evaluate the feasibility of a robot-controlled epiduroscopic system...

Total en bloc spondylectomy is a surgical technique cutting off tumors of spine and its satellite. Previous studies have shown that this technique could reduce postoperative recurrence rate of spinal tumor, but surgical indications are not unified. Wide application of spinal tumor surgical staging and life expectancy system make it more clear for surgery. However, it is difficult to carry out extensive operation for the characteristics of more bleeding, great difficulty and high risk. As for continuous improvement of TES technology, application of endoscopy and appearance of 3D printing artificial vertebral body could push the operation becoming mature...

BACKGROUND: Surgeries for far-lateral lumbar disc herniation (FLLDH) and foraminal stenosis at the L5/S1 level are very complicated because of its unique structure. The authors have performed unilateral bi-portal endoscopy (UBE) to these lesions because of the good results obtained for other spinal diseases (Park et al. in Orthopedics 40:e779-e783, 2017). METHODS: We described our experience of the surgical treatment for FLLDH and foraminal stenosis. Useful information for pre-, intraop-, and postoperative care is presented...

BACKGROUND: Lumbar spinal canal stenosis surgery has recently improved with the use of minimally invasive techniques. Less invasive procedures have emerged, and microendoscopic decompression through smaller incisions is frequently performed. Tubular surgery with the assistance of endoscopic surgery procedures has led to particularly remarkable changes in surgery, with reduced tissue trauma and morbidity. PURPOSE: The purpose of this study was to compare the clinical outcomes of two different minimally invasive decompressive surgical techniques (microendoscopic bilateral decompression surgery using the unilateral approach [microendoscopic laminectomy (MEL)] and microendoscopy-assisted muscle-preserving interlaminar decompression (MILD; ME-MILD)) using spinal endoscopy for lumbar spinal canal stenosis measured using a visual analog scale (VAS), the Japanese Orthopedic Association (JOA) score, and the JOA Back Pain Evaluation Questionnaire (JOABPEQ), which is based on a patient-oriented scoring system...

Full endoscopy spine surgery is one of the minimally invasive procedures for lumbar spine disease and is especially popular in East Asia. As for the interlaminar approach, lumbar recess stenosis can be manipulated through a uniportal bigger diameter working channel spinal endoscope or a smaller one, or a biportal arthroscope. Each kind of procedure has its advantages and shortcomings. Here, a novel experience in biportal interlaminar approach for lumbar recess stenosis is presented. A smaller uniportal spinal endoscope is adopted for biportal procedures rather than the arthroscope...

Background context: Open laminectomy has been regarded as the standard surgical method up to date in degenerative spinal stenosis or herniation of intervertebral disc. The conventional method may lead to instability and provoke chronic lower back pain by scarifying facet joint, posterior ligamentous complex as well as paraspinal muscle. For this reason, the new technique using an endoscope, which could protect soft tissue and facet joint, recently got spotlight. Purpose: The aim of this study is to introduce a new spinal surgical technique using a 30-degreed endoscopy through bi- or tri- portals and to report the preliminary result of this technique...

We report a case of meningeal carcinomatosis that needed to be distinguished from subarachnoid hemorrhage. A 67-year-old female with acute severe headache was admitted to a previous hospital. Since high intensity signal was detected within the parietal cerebral sulci on the right side on brain FLAIR MRI, cerebral angiography was performed due to suspicion of subarachnoid hemorrhage. However, no vascular abnormality was observed. Then, cerebral spinal fluid was collected, which showed an increase in cell count, suggesting meningitis...

This grand round raises the risk of a rare complication that can be avoided with the knowledge of the particular anatomy of scoliosis vertebra. Transpedicular screws have been reported to enhance the operative correction in scoliosis surgery. The narrow and inconsistent shape of the thoracic pedicles makes the placement of pedicle screws technically challenging. Furthermore, in thoracic curves, the close proximity of the spinal cord and major soft tissue structures also adds a greater risk to the procedure...
