Background: Preliminary definitions for SIJ lesions in the OMERACT Juvenile Idiopathic Arthritis Magnetic Resonance Imaging score has been reported 1 . Investigators identified need to revise JAMRIS-SIJ item definitions. Objectives: To update and scoring method. Methods: The JAMRI working group was convened discuss performance of a reliability exercise using 30 patients. Twenty investigators (1...

The sacroiliac joint (SIJ) was considered the primary source of low back pain in the early 20th century (1). It became overshadowed by the herniated nucleus pulposus after the hallmark 1934 article by Mixter and Barr (2). Mounting evidence on computed tomography (CT), magnetic resonance imaging (MRI), and scintography demonstrating destructive, inflammatory, and degenerative pathology (3-9) sug...

In this paper we prove a certain regularity property of configurations of immiscible fluids, filling a bounded container Ω and locally minimizing the interface energy ∑ i<j cij‖Sij‖, where Sij represents the interface between fluid i and fluid j, ‖ · ‖ stands for area or more general areatype functional, and cij is a positive coefficient. More precisely, we show that, under strict triangularity...

The objective of this study is to determine the three dimensional kinematics of the human pelvis including both sacroiliac joints following a simulated open book injury induced on cadavers by applying anterior-posterior compressive loads to the pelvis. An electromagnetic digitizing and motion tracking system was utilized to measure the morphology of the pelvis and the relative movements of its ...

BACKGROUND The anatomic characteristics of the sacroiliac joint (SIJ) make it difficult to achieve intraarticular injection without radiologic guidance. The classic C-arm guided SIJ intervention technique is difficult. Here we describe a new and simple method for SIJ intraarticular intervention. OBJECTIVE This study aims to introduce a new, simple approach for SIJ intraarticular intervention....

Numerous motion tests for diagnosing SIJ dysfunction have been described in the literature (van der Wurff et al 2000a & b). None is superior to another illustrating that physiotherapists should be suspicious with regard to the clinical relevance claimed by some authors. In general, motion tests of the SIJ can be reduced to 3 main directions: backward motion of the ilium (‘spine test’), forward ...

Background: Axial spondyloarthritis (axSpA) is clinically characterized by chronic inflammatory back pain and structural changes in the sacroiliac joint (SIJ) as assessed magnetic resonance imaging (MRI). Several studies have reported high rates of bone marrow edema (BME) suggestive SIJ up to 20% individuals general population &lt;45 years. An update definition a positive MRI axSpA for classifi...

The sacroiliac joint (SIJ) is an integral part of both the lumbar spine and the pelvic girdle. It is frequently the source of low back pain and pelvic girdle pain. Recent research has permitted a deeper understanding of its function and assessment. The mechanical assessment of the SIJ as a transmitter of load between trunk and lower limbs, and as a means to absorb torsion stresses of the pelvis...
