Physician spending is complex related to national health care spending, government regulations, health care reform, private insurers, physician practice, and patient utilization patterns. In determining payment rates for each service on the fee schedule, the Centers for Medicare and Medicaid Services (CMS) considers the amount of work required to provide a service, expenses related to maintaining a practice, and liability insurance costs. The value of 3 types of resources are adjusted on a yearly basis of the combined total multiplied by a standard dollar amount, called the fee schedules conversion factor, which was $33.98 in 2011, to arrive at the payment amount. ⋯ S. health care system. A historic reform, which has been passed by Congress and signed into law whose survivability is not quite known yet, is affecting medicine drastically in the United States. Interventional pain management, like other evolving specialties will probably most likely suffer under the new affordable health care law and regulatory burden.

Lead migration (LM) is the most common complication after spinal cord stimulation (SCS). Although multiple reports of caudad LM have been described, cephalad LM has not been reported. Here we describe a case in which a stimulator lead migrates in the cephalad direction. ⋯ We provide the first case report of significant cephalad LM following SCS lead implantation. This migration can occur despite the use of current standard anchoring techniques. Additional investigation into the mechanism of such LM and lead-securing techniques is warranted.

Randomized Controlled Trial
Fluoroscopic epidural injections in cervical spinal stenosis: preliminary results of a randomized, double-blind, active control trial.
Cervical spinal stenosis is a common disease that results in considerable morbidity and disability. There are multiple modalities of treatments, including surgical interventions and multiple interventional techniques including epidural injections. The literature on the effectiveness of cervical epidural steroids is sporadic. Emerging evidence for cervical interlaminar epidurals for various conditions in the cervical spine is positive; however, the effect of fluoroscopic epidural injections in cervical spinal stenosis has not been studied. ⋯ NCT01071369.

Case Reports
Autologous adipose tissue-derived stem cells induce persistent bone-like tissue in osteonecrotic femoral heads.
Osteonecrosis, also known as avascular necrosis, of the femoral head is a debilitating disorder that commonly affects 30- to 50-year-old individuals. Currently, definitive treatment is limited to total hip replacement. However, recent studies have demonstrated bone regeneration in the femoral head after the infusion of bone marrow-derived mesenchymal stem cells. In addition, local injection of adipose tissue-derived stem cells has been shown to regenerate medullary bone-like tissue 3 months after treatment. However, there have been no long-term follow-up studies on humans treated with adipose tissue-derived stem cells for osteonecrosis. ⋯ These 2 cases demonstrate the presence of sustained, regenerated medullary bone-like tissue in 2 severely necrotic femoral heads and suggest that this rather simple, minimally invasive percutaneous procedure may hold great promise as a therapy for patients with femoral head osteonecrosis.

Facial pain is a complex disease with a number of possible etiologies. Trigeminal neuropathic pain (TNP) is defined as pain caused by a lesion or disease of the trigeminal branch of the peripheral nervous system resulting in chronic facial pain over the distribution of the injured nerve. First line treatment of TNP includes management with anticonvulsant medication (carbamazepine, phenytoin, gabapentin, etc.), baclofen, and analgesics. ⋯ The patients in this case series continue to have significant symptomatic relief, demonstrating PNS as an effective treatment option for intractable TNP. Though there are no randomized trials, peripheral neuromodulation has been shown to be an effective means of treating TNP refractory to medical management in a growing number of case series. PNS is a safe procedure that can be performed even on patients that are not optimal surgical candidates and should be considered for patients suffering from TNP that have failed medical management.
