Coccygodynia is painful condition localized in the region of the coccyx. In most cases a traumatic etiology is present. In the idiopathic form other causes such as infections and tumor have to be excluded. ⋯ Treatment for patients with severe pain in the chronic phase consists of manual therapy and/or a local injection of local anesthetic and corticosteroid into the painful segment (2 C+). Other interventional treatments such as intradiscal injections, ganglion impar block, radiofrequency treatment and caudal block are advised only under study conditions (0). Coccygectomy is not recommended because of long-term moderate results and the chance of major complications.

An estimated 40% of chronic lumbosacral spinal pain is attributed to the discus intervertebralis. Degenerative changes following loss of hydration of the nucleus pulposus lead to circumferential or radial tears within the annulus fibrosus. Annular tears within the outer annulus stimulate the ingrowth of blood vessels and accompanying nociceptors into the outer and occasionally inner annulus. ⋯ There is currently insufficient proof to recommend intradiscal electrothermal therapy (2 B±) and intradiscal biacuplasty (0). It is advised that ozone discolysis, nucleoplasty, and targeted disc decompression should only be performed as part of a study protocol. Future studies should include more strict inclusion criteria.

Review Case Reports
Use of spinal cord stimulation in the treatment of phantom limb pain: case series and review of the literature.
Despite technical advances in spinal cord stimulation (SCS), there is a paucity of recent literature regarding SCS for phantom limb pain. ⋯ For selected patients who have not obtained adequate relief with medical management, SCS for phantom limb pain can prove an effective intervention.

Although the existence of a "facet syndrome" had long been questioned, it is now generally accepted as a clinical entity. Depending on the diagnostic criteria, the zygapophysial joints account for between 5% and 15% of cases of chronic, axial low back pain. Most commonly, facetogenic pain is the result of repetitive stress and/or cumulative low-level trauma, leading to inflammation and stretching of the joint capsule. ⋯ In patients with injection-confirmed zygapophysial joint pain, procedural interventions can be undertaken in the context of a multidisciplinary, multimodal treatment regimen that includes pharmacotherapy, physical therapy and regular exercise, and, if indicated, psychotherapy. Currently, the "gold standard" for treating facetogenic pain is radiofrequency treatment (1 B+). The evidence supporting intra-articular corticosteroids is limited; hence, this should be reserved for those individuals who do not respond to radiofrequency treatment (2 B±).

The sacroiliac joint accounts for approximately 16% to 30% of cases of chronic mechanical low back pain. Pain originating in the sacroiliac joint is predominantly perceived in the gluteal region, although pain is often referred into the lower and upper lumbar region, groin, abdomen, and/ or lower limb(s). Because sacroiliac joint pain is difficult to distinguish from other forms of low back pain based on history, different provocative maneuvers have been advocated. ⋯ Intra-articular sacroiliac joint infiltrations with local anesthetic and corticosteroids hold the highest evidence rating (1 B+). If the latter fail or produce only short-term effects, cooled radiofrequency treatment of the lateral branches of S1 to S3 (S4) is recommended (2 B+) if available. When this procedure cannot be used, (pulsed) radiofrequency procedures targeted at L5 dorsal ramus and lateral branches of S1 to S3 may be considered (2 C+).
