O-Arm Navigation-Guided Unilateral Biportal Endoscopic Decompression of Far-Out Syndrome.

The main aim of this video article is to demonstrate the combined use of O-arm navigation and unilateral biportal endoscopy (UBE) to manage far-out syndrome (FOS). In FOS there is entrapment and compression of the fifth lumbar nerve beyond the foramen and between L5 transverse process and the sacral ala at the lumbosacral junction. Conventional microscopic decompression using a paraspinal approach had been the gold standard for its management.

Hybrid Endoscopic Thoracic Discectomy Using Robotic Arm and Navigation for Highly Migrated Calcified Disc Herniation.

This video provides a step-by-step guide for performing the hybrid endoscopic thoracic discectomy using navigation and robotic arm for addressing high migrated calcified disc herniation. With the development of techniques, endoscopic spine surgery has emerged as a reliable treatment for thoracic myelopathy. This approach offers high-resolution, off-axis visualization of the surgical field.

Clinical Effects of Intraoperative Use of Tranexamic Acid in Minimally Invasive Scoliosis Surgery for Adolescent Idiopathic Scoliosis.

Background: To evaluate the clinical impact of intraoperative tranexamic acid administration in minimizing intraoperative blood loss and transfusion requirements during minimally invasive scoliosis surgery (MISS).

Methods: Consecutive data were collected from 97 patients with adolescent idiopathic scoliosis who underwent MISS between 2021 and 2023. Tranexamic acid was first introduced in June 2022.

Technical feasibility of combined uniportal unilateral laminotomy with bilateral decompression and interlaminar lumbar discectomy surgery for cauda equina syndrome due to lower lumbar disc herniation.

Background: Traditionally, open wide laminectomy and discectomy have been advocated for the treatment of cauda equina syndrome caused by lumbar disc herniation. We aimed to evaluate the technical feasibility of uniportal interlaminar endoscopy in treating cauda equina syndrome.

Methods: Nine patients with cauda equina syndrome underwent uniportal endoscopic decompression and discectomy from December 2020 to December 2022.

Unilateral biportal endoscopic supralaminar, posterior spinous process sparing approach for en bloc cervical laminectomy in case of cervical osteochondroma causing myelopathy: A case report.

Background Context: Cervical osteochondroma is a rare cause of myelopathy. Traditional treatment is open laminectomy with or without fusion. There is limited literature on unilateral bi-portal endoscopic en-bloc resection of cervical osteochondroma.

Spondylolysis of the Thoracic Spine with Instability: A Rare Cause for Myelopathy.

Case: A 51-year-old lady with multiple comorbidities presented with T11 spondylolysis in association with thoracic stenosis and myelopathy. Our patient underwent T11-T12 laminectomy, T10-L1 posterior instrumented stabilization, and T11-T12 transforaminal interbody fusion. She had a good neurological recovery, and the radiographs at 1-year follow-up showed good fusion and implant position.

Symptomatic Postsurgical Lumbar Pseudomeningocele Treated by Ultrasound-Guided Epidural Blood Patch Application.

Postsurgical pseudomeningoceles are extradural collections of cerebrospinal fluid (CSF) that results following an intraoperative dural breach. Although usually asymptomatic and self-subsiding, they may present with symptoms of postural headache, blurred vision, diplopia, photophobia, back pain, radiculopathy, and vomiting. Most of the cases recover with conservative measures such as bed rest, hydration, and pressure dressings.

Spinal Hypertrophic Pachymeningitis Causing Thoracic Myelopathy in a Patient of Takayasu Arteritis: A Case Report.

Case: A 52-year-old man presented with thoracic myelopathy, and his magnetic resonance imaging (MRI) was suggestive of T1-T4 hypertrophic-pachymeningitis. Incidentally, circumferential thickening of the infra-renal abdominal aorta and right common iliac artery was seen, which along with the findings in a contrast computed tomography was consistent with Takayasu arteritis (TA). The patient underwent T1-T4 laminectomy, thinning of dura, biopsy, and steroid therapy.
