Purpose: Neurosurgical ablative procedures, such as cordotomy and cingulotomy, are often considered irreversible and destructive but can provide an effective and individualized solution for cancer-related refractory pain, when all other approaches have been unsuccessful. This paper provides an in-depth exploration of a novel approach to managing refractory cancer pain. It involves an interdisciplinary team led by a neurosurgeon at a renowned national referral center.

The aim of this work was to evaluate three domains related to patients with lower back pain: the patients' perceptions, misconceptions and the experience of anxiety-related symptoms following direct access to their thoraco-lumbar spine radiology report. An additional aim was the assessment of possible associations with catastrophization.

: Subsequent osteoporotic vertebral fractures (SOVF) are a serious complication of osteoporosis that can lead to spinal deformity, chronic pain and disability. Several risk factors have been previously identified for developing SOVF. However, there are conflicting reports regarding the association between sarcopenia and multiple vertebral compression fractures.

Retro-laminar cervical blocks (RLCB) may be considered safer than ESI as they do not require entering the neuroaxis.In this study, we evaluated the outcome of RLCB in patients with cervical radiculopathy who had failed conservative treatment and were candidates for cervical spine decompression surgery.

The purpose of this study was to determine if specific morphological features of degenerative facet arthropathy are correlated with multifidus muscle atrophy. We retrospectively reviewed medical records and imaging studies of patients with lumbar spinal stenosis.
View Article and Find Full Text PDFA novel hybrid nanofluid was explored in order to find an efficient heat-transmitting fluid to replace standard fluids and revolutionary nanofluids. By using tangent hyperbolic hybrid combination nanoliquid with non-Newtonian ethylene glycol (EG) as a basis fluid and a copper (Cu) and titanium dioxide (TiO) mixture, this work aims to investigate the viscoelastic elements of the thermal transferring process. Flow and thermal facts, such as a slippery extended surface with magnetohydrodynamic (MHD), suction/injection, form factor, Joule heating, and thermal radiation effects, including changing thermal conductivity, were also integrated.

The purpose of this study is to compare the clinical outcome, complication and re-operation rates following minimally invasive (MIS) tubular decompression without arthrodesis in patients suffering from LSS with or without concomitant stable low-grade degenerative spondylolisthesis. This study is a retrospective review of prospectively collected data.

The side walls are adiabatic, and the internal and external borders of the cavity are isothermally kept at high and low temperatures of Th and Tc, respectively. The governing equations obtained with the Boussinesq approximation are solved using Galerkin Finite Element Method (GFEM).

It is still unclear whether early decompression results in better functional recovery and how soon surgery should be performed. This study aimed to evaluate predicting factors that affect short- and long-term recovery outcomes and to explore the relationship between timing of lumbar decompression and recovery from foot drop in an attempt to identify a cutoff time from symptom onset until decompression for optimal functional improvement.
