We provide a step-by-step technique guide for performing anterior cervical foraminotomy in this video. An illustrative case was presented with detailed narration and a discussion of surgical nuances. Anterior cervical foraminotomy can be an effective treatment strategy for patients with unilateral cervical radiculopathy without the need for cervical spine fusion. Spine surgeons should be familiar with technique and use it as a motion-preserving surgical option in treating isolated cervical radiculopathy. There is no identifying information in this video...

PURPOSE: Although cervical alignment is better assessed using standing radiography than supine magnetic resonance imaging (MRI), few studies have investigated this. This study aimed to investigate the difference in alignment between standing radiographs and supine MRI images, and assess whether neck position affects the cervical parameters and neurological changes. METHODS: We analyzed 53 patients, measuring the O-C2 angle, C2-7 angle (the distinction between the lordotic and kyphotic groups), T1 slope, neck tilt, thoracic inlet angle, and the C2-7 sagittal vertical axis...

Study Design: Systematic review. Objectives: Degenerative disc disease and spondylosis resulting in radiculopathy and retrodiscal myelopathy are among the most frequently encountered cervical spinal disorders. Traditionally, anterior cervical discectomy and fusion (ACDF) has successfully achieved neural decompression and restored intradiscal height in these conditions. Unfortunately, nonunion and iatrogenic adjacent segment pathology associated with fusion procedures in the cervical spine has led to an interest in motion-preserving procedures...

INTRODUCTION: Several studies have evaluated the efficacy of home use of chlorhexidine before surgery to reduce bacterial colonization. However, these studies have provided conflicting evidence about the potential efficacy of this strategy in decreasing bacterial loads and infection rates across surgical populations, and no prior study has analyzed the benefit of this intervention before spine surgery. We prospectively analyzed the effectiveness of chlorhexidine gluconate wipes for decreasing bacterial counts on the posterior neck...
