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.

National surveys suggest that millions of adults in the United States use complementary health approaches such as acupuncture, chiropractic manipulation, and herbal medicines to manage painful conditions such as arthritis, back pain, and fibromyalgia. Yet, national and per person out-of-pocket (OOP) costs attributable to this condition-specific use are unknown. In the 2007 National Health Interview Survey, the use of complementary health approaches, the reasons for this use, and the associated OOP costs were captured in a nationally representative sample of 5,467 adults. Ordinary least square regression models that controlled for comorbid conditions were used to estimate aggregate and per person OOP costs associated with 14 painful health conditions. Individuals using complementary approaches spent a total of $14.9 billion (standard error [SE] = $.9 billion) on these approaches to manage these painful conditions. Total OOP expenditures by those using complementary approaches for their back pain ($8.7 billion, SE = $.8 billion) far outstripped OOP expenditures for any other condition; the majority of these costs ($4.7 billion, SE = $.4 billion) were for visits to complementary providers. Annual condition-specific per person OOP costs varied from a low of $568 (SE = $144) for regular headaches to a high of $895 (SE = $163) for fibromyalgia. ⋯ Adults in the United States spent $14.9 billion on complementary health approaches (eg, acupuncture, chiropractic manipulation, and herbal medicines) to manage painful conditions including back pain ($8.7 billion). This back pain estimate is almost one-third of the total conventional health care expenditure for back pain ($30.4 billion) and two-thirds higher than conventional OOP expenditures ($5.1 billion).

Clinical TrialProspective Clinical and Radiographic Results of Activ L Total Disk Replacement at 1- to 3-Year Follow-up.
A prospective clinical study. ⋯ The 1- to 3-year follow-up of this cohort of patients showed satisfactory clinical outcomes. The IDHs at index and adjacent segments were well maintained after the surgery. The ROM at the lower adjacent segment remained unchanged, but the ROM at the index and upper adjacent segments showed a slight increase. The long-term results of activ L TDR was to be investigated.
