Randomized Controlled Trial
Effect of High-Volume Injectate in Lumbar Transforaminal Epidural Steroid Injections: A Randomized, Active Control Trial.
There have been many studies proving the effectiveness of lumbar transforaminal epidural steroid injections (TFESIs) for the treatment of radicular pain. Dexamethasone has been suggested as an alternative to particulate steroids. However, no controlled trials have investigated the effect of different injected volumes for a same dose of dexamethasone. ⋯ Injectate at a volume of 8 mL was more effective than injectate at a volume of 3 mL for radicular pain in a lumbar transforaminal steroid injection, although both of the injectates contained the same dose of dexamethasone.

To determine candidate lesion-based criteria for a positive sacroiliac joint (SIJ) MRI based on bone marrow oedema (BMO) and/or erosion in non-radiographic axial spondyloarthritis (nr-axSpA); to compare the performance of lesion-based criteria with global evaluation by expert readers. ⋯ Lesion-based criteria for a positive SIJ MRI based on both BMO and/or erosion performed best for classification of axial SpA, reflecting the contextual information provided by T1SE and STIR sequences.

Observational Study
Anatomic Evaluation of the Sacroiliac Joint: A Radiographic Study with Implications for Procedures.
Sacroiliac joint (SI) pain is increasingly being recognized as a source of low back pain. Injections and percutaneous type procedures are performed to treat symptomatic joints. However, there are limited studies available assessing the anatomy of the SI joint in vivo among patients with pain. ⋯ Treatment of the SI joint by surgeons and interventionalists is hampered by the limited number of anatomic studies in the literature. Our study presents the SI joint as a 2-limbed structure, sitting from slightly above the level of the PSIS rostrally to slightly below the level of the ASIS caudally. Palpation of these landmarks may assist in directing physicians to the joint. To begin an interventional pain procedure, with a patient lying prone, this data supports tilting the x-ray image intensifier 10 degrees caudal past the vertical anteroposterior (AP) view for optimal approach of the SI joint's inferior limb. The needle entry should be about 44.1 mm (1.75 inches) caudal to the PSIS. The image intensifier should have a 12 degree left lateral oblique view for injection of the right SI joint, and a 12 degree right lateral oblique view for the left SI joint.

Epidural corticosteroid injections are commonly used to treat back and leg pain associated with lumbar spinal stenosis. However, little is known about which patient characteristics may predict favorable responses. ⋯ Among 21 baseline patient characteristics examined, none, including clinician-rated spinal stenosis severity, were consistent predictors of benefit from epidural injections of lidocaine+corticosteroid versus lidocaine only.
