Bench top simulations have emerged as a powerful preclinical tool to predict the we...

OBJECTIVE The anterior approach for C7-T1 disc herniation may be challenging because of obstruction by the manubrium and the narrow operative field. This study aimed to investigate the clinical and neurological outcomes of anterior approach for C7-T1 disc herniation. METHODS We retrospectively evaluated 13 patients who underwent the anterior approach for C7-T1 disc herniation by a single surg...

BACKGROUND The ideal surgical approach for cervical disk disease remains controversial, especially for multilevel cervical disease. The purpose of this study was to investigate the biomechanics of the cervical spine after 3-level hybrid surgery compared with 3-level anterior cervical discectomy and fusion (ACDF). MATERIAL AND METHODS Eighteen human cadaveric spines (C2-T1) were evaluated unde...

Adjacent level cervical disc disease and secondarily progressive disc space degeneration that develops years after previously successful anterior cervical fusion at one or more levels is a common, but potentially complex problem to manage. The patient is faced with the option of further open surgery which involves adding another level of disc removal with fusion, posterior decompression, and st...

INTRODUCTION Titanium alloys are applied as the preferred endplate materials for artificial cervical disc because of their good mechanical properties, prominent biocompatibilities and corrosion resistance [1]. However, the poor tribological performances of titanium alloys might cause aseptic loosening and the osteolysis, which could lead to the failure of the replaced cervical disc implants [2,...

Through this paper work we have analyzed the effect of different contaminants on the flashover by creating artificial pollution condition, considering the natural condition where more than one salt as contaminant deposits on the surface of insulator at a time, under the wet condition that cause flow of highly leakage current, that leads to flashover. We choses the mixture of different salts, so...

background & importance: disc herniation is defined as the prolapsed of material disc into the spinal canal. if the disc fragment is free in spinal canal, it is called sequestration disc fragment. occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. case presentation: we reviewed a rare case of the cervical sequestrated disc herniation...
