Retrodiscal transforaminal (RdTF) epidural steroid injection (ESI) is clinically comparable to conventional transforaminal ESI and can avoid catastrophic complications. However, it poses a risk of inadvertent intradiscal, intravascular, and intrathecal injections. Therefore, we aimed to evaluate the feasibility of percutaneous epidural adhesiolysis (PEA) using the contralateral (Contra)-RdTF approach. ⋯ Although applications of this study are limited by its retrospective design, the results suggest that PEA using the Contra-RdTF approach is feasible because it can achieve EPR and avoid unintended fluoroscopic findings.

Thalamocortical dysfunction is thought to underlie the pathophysiology of chronic pain revealed by electroencephalographic studies. The thalamus serves as a primary relay center to transmit sensory information and motor impulses via dense connections with the somatosensory and motor cortex. In this study, diffusion tensor imaging (DTI) (probabilistic tractography) and resting-state functional magnetic resonance imaging (functional connectivity) were used to characterize the anatomical and functional integrity of the thalamo-sensorimotor pathway in chronic low back pain (cLBP). ⋯ Moreover, there was significantly altered resting-state functional connectivity (rsFC) of bilateral thalamo-motor/somatosensory pathways in patients with cLBP as compared to healthy controls. We also detected a significant correlation between pain intensity during the MRI scan and rsFC of the right thalamo-somatosensory pathway in cLBP. Our findings highlight the involvement of the thalamo-sensorimotor circuit in the pathophysiology of cLBP.

The benefits of clinical practice guideline (CPG) adoption for the management of patients with back pain are well documented. However, the gap between knowledge creation and implementation remains wide with few studies documenting the iterative process of comprehensive implementation in clinical settings. The objective of this study was to improve adherent physical therapy care according to CPG's for low back pain and describe the knowledge to action (K2A) process used in a rural healthcare organization. ⋯ This study extends the literature of guideline implementation by describing the unique cycles required for promoting provider behaviour change within a rural healthcare system. Adherence and confidence results suggest increased provider CPG use which was supported by the process evaluation. This study demonstrates the importance of multiple site comparisons, long-term reporting and standardized frameworks for assessment of real-world CPG implementation.

Vertebral endplate lesion (EPL) caused by severe disc degeneration is associated with low back pain. However, there is no suitable animal model to elucidate the pathophysiology of EPL. This study aimed to develop a rat model of EPL and evaluate rat behavior and imaging and histological findings. ⋯ Our rat EPL model showed pain-related behavioral patterns and an increased expression of pain-related neuropeptide. This model could contribute to the study of the pathophysiology of EPL and will help in the treatment of low back pain in the future.
