Review Case Reports
The Best-Laid Plans of "Back Mice" and Men: A Case Report and Literature Review of Episacroiliac Lipoma.
Back mice, or episacroiliac lipoma, represent a potentially treatable cause of low back pain that may be under-recognized in clinical practice. Despite being well characterized based on clinical history and physical examination findings, implementation of appropriate treatment may be delayed or missed based on a lack of familiarity with the diagnosis. ⋯ Firm, rubbery, mobile nodules that are located in characteristic regions of the sacroiliac, posterior superior iliac, and the lumbar paraspinal regions may represent fatty tissue that has herniated through fascial layers. When painful, these back mice may be confused with other causes of low back pain. In particular, the presence of point tenderness may mimic myofascial pain, and reports of radicular pain may imitate herniated nucleus pulposus. However, back mice may be distinguished from other entities based on findings from the history and physical examination such as absence of neurological deficit. Treatment consisting of injection of local anesthetic into the nodule with or without corticosteroid followed by repeated, direct needling has been reported to relieve pain in many case reports. The one clinical trial comparing injection of local anesthetic to normal saline, which did not include repeated needling, found only mild and transient benefit in the treatment group.

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.

Review Meta Analysis Comparative Study
Epidural Injections for Lumbar Radiculopathy and Spinal Stenosis: A Comparative Systematic Review and Meta-Analysis.
The prevalence of chronic low back pain and related disability is rapidly increasing as are the myriad treatments, including epidural injections. Even though epidural injections are one of the most commonly performed procedures in managing low back and lower extremity pain, starting in 1901 with local anesthetic alone, conflicting recommendations have been provided, despite the extensive literature. Recently Chou et al performed a technology assessment review for Agency for Healthcare Research and Quality (AHRQ) part of which was published in Annals of Internal Medicine showing lack of effectiveness of epidural steroid injections in managing lumbar radiculopathy and spinal stenosis. In contrast, multiple other publications have supported the efficacy and use of epidural injections. ⋯ Epidural corticosteroid injections for radiculopathy or spinal stenosis with sodium chloride solution or bupivacaine were shown to be ineffective. Lidocaine alone or lidocaine in conjunction with steroids were significantly effective.

Review Case Reports
Thoracic Nerve Root Entrapment by Intrathecal Catheter Coiling: Case Report and Review of the Literature.
Intrathecal catheter placement has long-term therapeutic benefits in the management of chronic, intractable pain. Despite the diverse clinical applicability and rising prevalence of implantable drug delivery systems in pain medicine, the spectrum of complications associated with intrathecal catheterization remains largely understudied and underreported in the literature. ⋯ This case demonstrates that any existing loops in the intrathecal catheter during initial implantation should be immediately re-addressed, as they can precipitate nerve root entrapment and irritation. Reduction of the loop or extrication of the catheter should be attempted under continuous fluoroscopic guidance to prevent further neurosurgical morbidity.
