Transforaminal epidural steroid injection (TFESI) of corticosteroid is frequently employed to mitigate the painful and disabling symptoms of lumbar disc herniation. However, the treatment outcome of TFESI in patients with radicular pain and inflamed neural structures as assessed by contrast-enhanced magnetic resonance imaging (MRI) has not been forthcoming. ⋯ The improvement of NRS and ODI in the enhanced group was significantly greater than those of the non-enhanced group after TFESI. Radicular pain and functional impairment in the presence of gadolinium enhancing spinal neural structures and lumbar disc herniation may be more responsive to TFESI than patients without enhancing neural structures.

The obturator internus (OI) muscle is important in adult chronic noninfectious pelvic, perineal, gluteal, and retrotrochanteric pain syndromes. Evaluation and management of these patients' pain can be challenging because of the complex anatomy of this region, broad differential diagnosis, and lack of specific physical examination findings. Consequently, several clinicians have advocated the use of image guided injections to assist in the accurate diagnosis of OI-related symptoms and provide symptomatic relief to affected patients. ⋯ The second patient underwent a right intrapelvic OI muscle injection with bupivacaine 0.25% and 40 mg methylprednisolone. The average pre- and postprocedural visual analog scale scores were 8 out of 10 and 1 out of 10, respectively, with a self-reported 90% pain reduction. Larger scale studies should be undertaken to evaluate the therapeutic efficacy and generalized accuracy of this technique.

Spina bifida is a common birth defect affecting the central nervous system and represents a group of neural tube defects caused by congenital dysraphic malformations of the vertebral column and/or spinal cord. The anatomy in these patients is challenging and includes structural and vascular abnormalities including arteriovenous malformation or fistulae, and fatty substitution of paravertebral tissues. ⋯ Occult spinal dysraphism poses a clinical dilemma for interventional pain specialists managing those patients with lumbar radiculopathy. We report a case of occult spinal dysraphism discovered following the development of post-traumatic radicular symptoms.

Temporomandibular joint syndrome, or Costen syndrome, is a clinically diagnosed disorder whose most common symptoms include joint pain and clicking, difficulty opening the mouth, and temporomandibular joint discomfort. The temporomandibular joint (TMJ) is supplied by the auriculotemporal nerve, a collateral branch of the mandibular nerve (the V3 branch of the trigeminal nerve). ⋯ Patients affected with TMJ syndrome who do not respond to conservative treatments may find a solution in peripheral nerve stimulation, a simple technique with a relatively low level of complications.

The rapid increase in the prevalence of chronic pain and disability, and the explosion of interventional pain management associated health care costs are a major concern for our community. Further, the increasing utilization of numerous modalities of treatments in managing chronic pain, continue to escalate at a pace which may not be sustainable. There are multiple regulations in place to control the growth of health care expenditures which seem to have been largely ineffective. Among the various modalities utilized in managing chronic pain, interventional techniques have shown a significant increase in their utilization in the face of continued debate with respect to the accuracy of diagnostic interventions and the efficacy of therapeutic interventions. ⋯ This update once again shows a significant increase in interventional techniques in fee-for-service Medicare beneficiaries from 2000 through 2013 with an increase of 156% per 100,000 Medicare population with an annual average increase of 7.5%. During this period the Medicare population increased 31% with an annual average increase of 2.1%.
