Review Meta Analysis Comparative Study
Full-Endoscopic Procedures Versus Traditional Discectomy Surgery for Discectomy: A Systematic Review and Meta-analysis of Current Global Clinical Trials.
Traditional discectomy surgery (TDS) provides good or excellent results in clinical surgical discectomy but may induce neural adhesion, spinal structural damage, instability, and other complications. The potential advantages of full-endoscopic (FE) procedures over standard TDS include less blood loss, less postoperative pain, shorter hospitalization, and an earlier return to work. However, more evidence is needed to support this new technology in clinical applications. ⋯ Based on this meta-analysis of 24 months of clinical results, we conclude that the FE procedure is as effective as TDS but has the additional benefits of lower complication rates and superior perioperative parameters. In addition, patients may experience less pain with FE techniques due to a smaller incision and less operative injury. However, large-volume, well-designed RCTs with extensive follow-up are needed to confirm and update the findings of this analysis.

This a unique case of severe scapular pain following unintentional epidural space air injection during epidural steroid injection. A 70-year-old woman presented for a fluoroscopically guided C7-T1 interlaminar epidural steroid injection. Three injection attempts were made using the loss of resistance with air technique. ⋯ The authors theorize that unintentional prefilling of the epidural space with air prior to the injection of the subsequent steroid mixture added sufficient pressure to the epidural space to cause right-sided C4 nerve root stretching/entrapment and ensuing radicular pain to the right scapular border. The subsequent intravenous diazepam provided cervical muscle relaxation and facilitated foramina passage of air out of the spinal canal. This case demonstrates that under certain conditions entry of air into cervical epidural space can lead to unexpected, albeit temporary, neurological symptoms.

Although the prevalence of sacroiliac joint (SIJ) pain is relatively high (15 - 30%), there is no unambiguous reference standard to diagnose SIJ pain. Pressure tenderness in the SIJ region is used for diagnostic purposes, but the clinimetric properties of this procedure remain to be determined. ⋯ Pressure pain algometry appears to be a reliable method to establish differences in PPTs between healthy volunteers and patients with SIJ pain. The diagnostic accuracy of this test should be investigated further.

Pudendal neuralgia is a chronic neuropathic pelvic pain that is often misdiagnosed and inappropriately treated. The Nantes criteria provide a basis for the diagnosis of pudendal neuralgia due to pudendal nerve entrapment. The 5 essential diagnostic criteria are pain situated in the anatomical territory of the pudendal nerve, worsened by sitting, the patient is not woken at night by the pain, and no objective sensory loss is detected on clinical examination. ⋯ In these atypical presentations, the diagnosis of pain due to pudendal nerve entrapment should be reconsidered and a radiological examination should be performed. The 2 cases described in this report (tumor compression of the pudendal nerve) illustrate the need to recognize atypical pudendal neuralgia and clarify the role of pelvic magnetic resonance imaging (MRI), as MRI provides very valuable information for the evaluation of diseases involving the ischiorectal fossa. The presence of red flags must be investigated in all cases of pudendal neuralgia to avoid missing pudendal neuralgia secondary to a mechanism other than nerve entrapment.
