OBJECTIVE: Postoperative epidural adhesion is one of the most frequent causes of failed-back surgery syndrome, presenting with back and leg pain or neurological deficits. Development of preventive measures for epidural adhesion after laminectomy remains critical to improve the outcomes of lumbar surgery. We hypothesized that positive effects of the topical application of Contractubex®Gel and benzothiazole individually and in combination can aid in the prevention of epidural fibrosis in a rat laminectomy model...

INTRODUCTION: Hirayama disease is a rare cervical myelopathy predominantly affecting young adults and mainly found in Asia. It results in a pure motor distal lesion of the upper limbs with slow progression. Dynamic magnetic resonance imaging (MRI), which allows the diagnosis to be made, shows a typical appearance of anterior compression of the cervical spinal cord associated with enlargement of the posterior epidural spaces due to a dilated venous plexus. Surgery is considered when conservative treatment has failed...

Interspinous process devices (IPDs) have been developed as less-invasive alternatives to spinal fusion with the goal of decompressing the spinal canal and preserving segmental motion. IPD implantation is proposed to treat symptoms of lumbar spinal stenosis that improve during flexion. Recent indications of IPD include lumbar facet joint syndrome, which is seen in patients with mainly low-back pain. Long-term outcomes in this subset of patients are largely unknown. The authors present a previously unreported complication of coflex (IPD) placement: the development of a large compressive lumbar synovial cyst...

Mouse models are unique for studying molecular mechanisms of neurotrauma due to the availability of various genetic modified mouse lines. For spinal cord injury (SCI) research, producing an accurate injury is essential but is challenging due to the small size of the mouse cord and inconsistency of injury production. The Louisville Injury System Apparatus (LISA) impactor has been shown to produce precise contusive SCI in adult rats. Here we examined whether the LISA impactor could be used to create accurate and graded contusive SCIs in mice...

BACKGROUND: Safe excision of spinal cord tumors depends on sufficient visualization of the tumor and surrounding structures. In patients with spinal cord tumor adjacent to a stenotic spinal canal, extensive bony decompression proximal and distal to the tumor should be considered for safer excision of the tumor. Extensive wide laminectomy is one choice for such cases, but postoperative problems such as kyphotic deformity remain a concern. CASE PRESENTATION: A 76-year-old man and a 60-year-old woman presented with symptomatic intradural extramedullary spinal cord tumors in the cervical spine...

BACKGROUND AND IMPORTANCE: Myopericytoma is an emerging class of neoplasm originating from the perivascular myoid cellular environment, previously classified as a variant of hemangiopericytoma. Most reported myopericytomas are found in soft tissues of the extremities; however, infrequent cases are described involving the central nervous system. Intracranial myopericytoma remains rare. Here, we describe the first report of myopericytoma occurring at the cervicomedullary junction in close proximity to the vertebral artery, mimicking a vascular lesion...

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...

The study aimed to review the etiology of failed back surgery syndrome (FBSS) and to propose a treatment algorithm based on a systematic review of the current literature and individual experience. FBSS is a term that groups the conditions with recurring low back pain after spine surgery with or without a radicular component. Since the information on FBSS incidence is limited, data needs to be retrieved from old studies. It is generally accepted that its incidence ranges between 10% and 40% after lumbar laminectomy with or without fusion...

BACKGROUND: Symptomatic sacral Tarlov cysts have been associated with perineal or sacral pain, radiculopathy, urinary dysfunction. The ideal treatment of symptomatic sacral Tarlov cysts remains a matter of discussion. Numerous open surgical procedures have been proposed, which vary from placement of shunts and clipping to laminectomy and fenestration. And those surgeries often associated with recurrence, cerebrospinal fluid leakage, infection and other complications. At present, no percutaneous endoscopic surgical procedures have been reported to solve this problem...
