INTRODUCTION: Post-operative wound infections after spinal surgery is a very serious problem, leading to a risk of significant morbidity which may even lead to prolonged hospitalization. Various treatment protocols have been recommended for debridement, antibiotic, and soft-tissue management, but with mixed results. However, the risk of morbidity is still high with these treatment options. Vacuum-assisted closure (VAC) system has been gaining popularity recently in the management of subacute, acute, and chronic wounds...

PURPOSE: Postoperative spinal epidural hematoma (PSEH) is one of the most hazardous complications after spine surgery. A recent study has reported that a ≥50 mmHg increase in systolic blood pressure after extubation was a significant risk factor for symptomatic PSEH. In this paper, the impact of hypertension on PSEH occurrence was investigated. METHODS: Among a total of 2468 patients who underwent single level microscopic posterior decompression surgery for lumbar spinal stenosis in a single institute, 15 (0...

Patients with metastatic disease including polymetastatic, oligometastatic, and oligorecurrent spinal lesions have extended life expectancy secondary to improvements in systemic agents, and thus require durable local control of spine metastases. Stereotactic body radiotherapy (SBRT), which uses highly conformal treatment planning techniques coupled with image-guided technology, has enabled the safe delivery of tumor-ablative doses of radiotherapy. The NOMS decision framework has been developed as a tool to aid in the determination of the optimal treatment of spinal metastases, incorporating radiosurgery, separation surgery, stabilization techniques, and conventional radiation...

In a random sample of postmenopausal Chinese women, the prevalence of radiographic vertebral fractures increased from 13% between ages 50 and 59 to over 50% after age 80 years. A model with seven clinical risk factors predicted the probability of vertebral fractures as well with as without BMD and better than a model with only three risk factors. More than half an hour of outdoor activity per day might correlate with lower risk of vertebral fracture in this population. INTRODUCTION: We aimed to describe the prevalence and develop a model for prediction of radiographic vertebral fractures in a large random sample of postmenopausal Chinese women...

Dual energy X-ray absorptiometry (DXA) is the standard for assessing fragility fracture risk using areal bone mineral density (aBMD), but only explains 60-70% of the variation in bone strength. High-resolution peripheral quantitative computed tomography (HR-pQCT) provides 3D-measures of bone microarchitecture and volumetric bone mineral density (vBMD), but only at the wrist and ankle. Finite element (FE) models can estimate bone strength with 86-95% precision. The purpose of this study is to determine how well vBMD and FE bone strength at the wrist and ankle relate to fracture strength at the hip and spine, and to compare these relationships with DXA measured directly at those axial sites...

BACKGROUND: Pedicle screw misplacement rates are relatively high with fluoroscopically guided techniques. However, breach rates in the 5th lumbar and the 1st sacral spines in conventional operations have not been specifically concerned because of their broad cross sections. It's a retrospective study to evaluate the accuracy and safety of pedicle screw placement in posterior lumbosacral instrumentation under CT scan with reconstruction. MATERIALS AND METHODS: 401 patients were evaluated under CT scan with reconstruction in 3 hospitals by 2 professional observers after posterior lumbosacral instrumentation including 152 3rd lumbar spines (L3), 219 4th lumbar spines (L4), 270 5th lumbar spines (L5) and 95 1st sacral spines (S1) with screws placed...

REVIEW
Tochukwu C Ikpeze, Addisu Mesfin
Spinal cord injuries (SCIs) are sustained by more than 12 500 patients per year in the United States and more globally. The SCIs disproportionately affect the elderly, especially men. Approximately 60% of these injuries are sustained traumatically through falls, but nontraumatic causes including infections, tumors, and medication-related epidural bleeding have also been documented. Preexisting conditions such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis can render the spine stiff and are risk factors as well as cervical spondylosis and ensuing cervical stenosis...
