Chronic pain is distressing for patients and a burden on healthcare systems and society. Recent research demonstrates different aspects of the negative impact of chronic pain and the positive impact of successful treatment, making an overview of the costs and consequences of chronic pain appropriate. ⋯ Strenuous efforts should be put into obtaining good levels of pain relief for people in chronic pain, including the opportunity for multiple drug switching, using reliable, validated, and relatively easily applied patient-centered outcomes. Detailed, thoughtful and informed decision analytic policy modeling would help understand the key elements in organizational change or service reengineering to plan the optimum pain management strategy to maximize pain relief and its stream of benefits against budgetary and other constraints. This paper contains the information on which such models can be based.

Patients who suffer from the condition known as failed back surgery syndrome (FBSS) present to the offices of physicians, surgeons, and pain specialists alike in overwhelming numbers. This condition has been defined as persistent back and/or leg pain despite having completed spinal surgery. As lumbar surgery continues to grow in prevalence, so will the number patients suffering from FBSS. ⋯ The most invasive treatment option, short of revision surgery, is spinal cord stimulation. This intervention has a number of studies demonstrating its efficacy and cost-effectiveness in this population. Finally, revision surgery may be used when indicated such as with progressive neurological impairment or with issues regarding previous surgical instrumentation.

Review Case Reports
Patients with a History of Spine Surgery or Spinal Injury may have a Higher Chance of Intrathecal Catheter Granuloma Formation.
Intrathecal drug delivery is an effective method to treat intractable pain. However, intrathecal catheter tip granuloma (ICTG) is a devastating complication of intrathecal drug delivery systems. It typically occurs in the thoracic region; particularly, in patients receiving high doses or high concentrations of intrathecal drug infusions. ⋯ Cerebrospinal fluid flow dynamics within the spinal canal along with the physical, chemical, and immunological properties of intrathecal medications have been suggested to be responsible for the growth of inflammatory mass lesions at the tips of intrathecal drug delivery catheters. Our literature review supports the possible role of certain factors, specifically previous spine surgery or spinal injury, in granuloma formation. The rate of development of ICTG appears to be higher in patients who have had previous spine surgery or spinal injury (68%) than in a general cohort of patients (48%), with an intrathecal pump. Therefore patients with a history of spine surgery or injury may be at increased risk of ICTG when receiving chronic intrathecal analgesia.

There is convincing evidence that inflammation plays a pivotal role in the pathophysiology of complex regional pain syndrome (CRPS). Besides inflammation, central sensitization is also an important phenomenon. ⋯ In the development of a more mechanism-based treatment, influencing the activity of mast cells might be important in the treatment of CRPS. We describe the rationale for using medication that counteracts the effects of mast cells in the treatment of CRPS.
