The positive effects of percutaneous epidural neuroplasty (PEN) likely result from elimination of fibrous tissue. However, a direct link between epidural adhesions and pain symptoms is debatable. We tested the hypothesis that epidurographic improvements correspond to improved patient outcome. ⋯ The epidurographic changes following PEN correlate with patient-assessed pain relief and satisfaction.

The increase in the number of interventions for the management of chronic pain and associated escalation of healthcare costs has captured the attention of health policymakers, in no small part due to the lack of documentation of efficacy, cost-effectiveness, or cost utility analysis. A recent cost utility analysis of caudal epidural injections in managing chronic low back pain of various pathologies showed a high cost utility with improvement in quality of life years, competitive with various other modalities of treatments. However, there are no analyses derived from high-quality controlled studies related to the cost utility of percutaneous adhesiolysis in the treatment of post-lumbar surgery syndrome or lumbar central spinal stenosis. ⋯ This cost utility analysis of percutaneous adhesiolysis in the treatment of post-lumbar surgery syndrome and lumbar central spinal stenosis shows the clinical effectiveness and cost utility of these procedures at USD $2,650 per one year of QALY when performed in an ambulatory surgery center.

Observational Study
Optimal Angle of Needle Insertion for Fluoroscopy-Guided Transforaminal Epidural Injection of L5.
Unlike other sites, there is difficulty in performing TFESI at the L5-S1 level because the iliac crest is an obstacle to needle placement. ⋯ When TFESI is performed at the L5 region in the prone position, placement of fluoroscopy at a cephalocaudal angle of 11.0° and an oblique angle of 25° in men and cephalocaudal angle of 13.9° and an oblique angle of 30° in women would be most reasonable.
