Cervical transforaminal epidural steroid injection (TFESI) is considered one of the most effective treatments for radicular pain induced by cervical foraminal stenosis. ⋯ The treatment outcome of cervical TFESI did not different according to the severity of cervical foraminal stenosis. However, on the basis of our results, we suggest that TFESI can be a beneficial clinical option for managing radicular pain due to cervical foraminal stenosis.

Although microvascular decompression (MVD) has been widely accepted as an effective treatment for hemifacial spasm (HFS), some patients may experience delayed relief instead of immediate improvement after the surgery. The need for and timing of repeat MVD has been controversial to date; thus, we conducted the present study with emphasis on those unrelieved patients. ⋯ Our findings demonstrate that MVD is the most effective treatment for patients with HFS. An early reoperation is easier and safer than a later reoperation and may improve the likelihood of immediate relief.

To evaluate stability of anterior transdiscal axial screw (ATAS) fixation for anterior instrumentation and to compare with standard anterior cervical decompression and fusion and plate (ACDFP) fixation in human subaxial cervical spine. ⋯ ATAS fixation is a biomechanically effective alternative or supplemental method of anterior fixation in subaxial cervical spine.

The causes of chronic diskogenic back pain have not yet been clearly identified. Neural ingrowth around the annulus is widely considered to be one of the possible cause. However, neuropathy around the annulus has yet to be observed visually. We report a case of a hotspot that was observed in an epiduroscopic view, but not in imaging findings. ⋯ In this study, we observed annulus hotspots, which have not been observed in imaging studies such as computed tomography or magnetic resonance imaging in patients with chronic back pain and leg pain, and observed remarkable symptom improvement after transforaminal epiduroscopic laser ablation.
