This study assessed the relationship of the vertebral artery and the transverse foramens in the lower cervical spine by computer tomographic angiography (CTA) measurements. ⋯ Vertebral artery is in the medial part of transverse foramen. There is a relative "abundance space" for vertebral artery in transverse foramen.

This study was designed to verify the hypothesis of a constant, antidromic activation of fibers traveling along peripheral sensory nerves during spinal cord stimulation (SCS). ⋯ The authors hypothesize that this antidromic activation could represent a possible antalgic mechanism of SCS in patients with peripheral neuropathic pain, but further neurophysiological studies will be needed to elucidate this hypothesis.

Review Meta Analysis Comparative Study
Examining heterogeneity in meta-analysis: comparing results of randomized trials and nonrandomized studies of interventions for low back pain.
Literature review. ⋯ Comparisons between RCTs and NRSs may be influenced by various factors, including study design. However, other factors were more powerful explanatory variables than study design. These factors included pain duration, involvement of workers' compensation, presence of spondylolisthesis, previous surgery, and levels fused.

Randomized Controlled Trial Comparative Study
Two-year outcome after lumbar microdiscectomy versus microscopic sequestrectomy: part 2: radiographic evaluation and correlation with clinical outcome.
Single-center randomized prospective study at a university hospital. ⋯ Nondiscal pathologies, in particular Modic type endplate changes, seem to play an important role in the etiology of unfavorable clinical outcome after surgery for disc herniations. Sequestrectomy demonstrated significantly less postoperative disc degeneration than standard microdiscectomy after 2 years and may thus represent an attractive treatment alternative.

Randomized Controlled Trial Comparative Study
Two-year outcome after lumbar microdiscectomy versus microscopic sequestrectomy: part 1: evaluation of clinical outcome.
Single-center randomized prospective study at a university hospital. ⋯ Reherniation rates within 2 years after sequestrectomy and microdiscectomy are comparable. However, outcome after microdiscectomy seems to worsen over time, whereas it remains stable after sequestrectomy. Thus, 2-year follow-up revealed clinical results favoring sequestrectomy. Performing sequestrectomy alone may therefore represent an advantageous alternative to standard microdiscectomy.
