Spine is a common site of metastases in cancer patients. Spine surgery is indicated for select patients, typically those with mechanical instability and/or malignant epidural spinal cord (or cauda equina) compression. Although post-operative conventional palliative external beam radiation therapy has been the standard of care, technical improvements in radiation planning and image-guided radiotherapy have allowed for the application of stereotactic body radiotherapy (SBRT) to the spine. Spine SBRT is intended to ablate residual tumor and optimize local control by delivering several fold greater biologically effective doses...

INTRODUCTION: The stabilization of an atlantoaxial (C1-C2) instability is demanding due to a complex atlantoaxial anatomy with proximity to the spinal cord, a variable run of the vertebral artery (VA) and narrow C2 pedicles. We perfomed the Goel & Harms fusion in combination with an intraoperative 3D imaging to ensure correct screw placement in the C2 pedicle. We hypothesized, that narrow C2 pedicles lead to a higher malposition rate of screws by perforation of the pedicle wall. The purpose of this study was to describe a certain pedicle size, under which the perforation rate rises...

STUDY DESIGN: Case report. OBJECTIVE: To report the first case in the literature of a traumatic cervical spine subdural cerebrospinal fluid (CSF) collection (hygroma) under tension causing cord compression. We suggest etiopathogenesis and modality of treatment. SUMMARY OF BACKGROUND DATA: Hygromas are subdural cranial CSF collection. A literature review showed no previous published case of post-traumatic spinal hygroma. This was a potential life-threatening sequelae of a high cervical injury that warranted early diagnosis and emergency treatment...

BACKGROUND: In patients with spinal metastatic disease, survival prognosis is a key consideration in selection for surgery and determining the extent of treatment. Individual survival prediction however remains difficult. We sought to validate the prognostic accuracy of seven preoperative scoring systems. METHODS: 61 patients surgically treated for spinal metastases were retrospectively reviewed. Preoperative scores were calculated for Tokuhashi, Revised Tokuhashi, Bauer, Modified Bauer, Sioutos, Tomita, and van der Linden scoring systems...

BACKGROUND CONTEXT: Conventional laminoplasty is useful for expanding a stenotic spinal canal. However, it has limited use for the decompression of accompanying neural foraminal stenosis. As such, an additional posterior foraminotomy could be simultaneously applied, although this procedure carries a risk of segmental kyphosis and instability. PURPOSE: The aim was to elucidate the long-term surgical outcomes of additional posterior foraminotomy with a laminoplasty for cervical spondylotic myelopathy (CSM) with radiculopathy...

OBJECTIVE: Laminoplasty is an effective surgical method for treating cervical degenerative disease. However, postoperative complications such as kyphosis, restriction of neck motion, and instability are often reported. Despite sufficient preoperative lordosis, this procedure often aggravates the lordotic curve of the cervical spine and straightens cervical alignment. Hence, it is important to examine preoperative risk factors associated with postoperative kyphotic alignment changes. Our study aimed to investigate preoperative radiologic parameters associated with kyphotic deformity post laminoplasty...

There is considerable interest in developing diagnostic nanotools for early detection and delivery of various therapeutic agents for treatment of neurodegenerative diseases. However, a key challenge remains in the selection of suitable surfaces to overcome the nano-bio interface issue, namely that many nanoparticle surfaces demonstrate instability when administered into biological environments and show substantial cytotoxicity to the central nervous system. In this study, we fabricated an evaluation platform for bio-nano surface selection based on the combination of upconversion nanoparticles (UCNPs), cultured neural cells and zebra fish, and systemically demonstrated how it can evaluate the suitability of nanoparticle surfaces for applications in the central nervous system...

R Kothe
Low back pain (LBP) in patients with rheumatoid arthritis (RA) has so far been of little concern in clinical investigations. The main focus of scientific publications on spinal problems in RA was the cervical spine. In a recent study, we could demonstrate that LBP in RA patients leads to a significantly higher degree of disability and depression as well as to a reduction in quality of life compared to RA patients without LBP. If there is a specific reason for the additional symptom of LBP, such as spinal stenosis or segmental instability, surgical treatment may be indicated to improve disability and quality of life...

BACKGROUND: Plasma cell neoplasmas are a heterogenous group of neoplastic tumor lesions occurring secondary to disordered proliferation of cells from a monocyte lineage. Plasmacytoma is a rare lesion that accounts for 5% of all plasma cell neoplasms. The current recommended treatment for solitary plasmacytoma is moderate dose radiation therapy. For patients who are suffering from axial back pain, spinal instability, radiculopathy, or bowel/bladder dysfunction secondary to spinal cord compression, surgical intervention with spinal decompression and stabilization can be used as an adjuvant to radiation therapy...

Chondroitinase ABC I (cABC I) cleaves glycosaminoglycan chains which are responsible for most of the inhibition of axon regrowth in spinal cord injury. The application of chondroitinase ABC I (cABC I) in damaged nervous tissue is found to prune glycosaminoglycan chains of proteoglycans and facilitate axon regeneration. However, a limiting factor for such application is the enzyme's instability. In this study, the structure and activity of cABC I have been investigated upon interaction with various concentrations of Gold nanorods...

Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy...
