J Anat 2018 Dec 9. Epub 2018 Dec 9.

Fraunhofer Institute for Machine Tools and Forming Technology IWU, Dresden, Germany.

The sacroiliac joint (SIJ) is a well-known source of low back and pelvic pain, of increasing interest for both conservative and surgical treatment. Alterations in the kinematics of the pelvis have been hypothesized as a major cause of SIJ-related pain. However, definitions of both the range and the extent of physiological movement are controversial, and there are no clear baseline data for pathological alterations. Read More

A Randomized Controlled Trial of Fluoroscopically-Guided Sacroiliac Joint Injections: A Comparison of the Posteroanterior and Classical Oblique Techniques.

Neurospine 2018 Oct 7. Epub 2018 Oct 7.

Anesthesiology, Pain management, and Perioperative Medicine, Henry Ford Health System, Detroit, MI, USA.

Objective: The sacroiliac joint can be a primary source of pain or part of multifactorial syndromes. As there is no single historical, physical examination-based, or radiological feature that definitively establishes a diagnosis of sacroiliac joint pain, diagnostic blocks are regarded as the gold standard. The primary aim of this randomized trial was to compare the posteroanterior approach with the classic oblique approach for sacroiliac joint injection based on an assessment of procedure times and patient-reported pain outcomes in subjects scheduled for fluoroscopically-guided sacroiliac joint injections.

The Early Phases of Ankylosing Spondylitis: Emerging Insights From Clinical and Basic Science.

Front Immunol 2018 16;9:2668. Epub 2018 Nov 16.

Section of Musculoskeletal Disease, Leeds Institute of Molecular Medicine, University of Leeds, NIHR Leeds Musculoskeletal Biomedical Research Unit, Chapel Allerton Hospital, Leeds, United Kingdom.

In our paper, we discuss how the early phases of ankylosing spondylitis (AS) are linked to peri-firbocartilagenous osteitis in the sacroiliac joint and entheseal bone related anchoring sites. This skeletal proclivity is linked to an abnormal immunological response to skeletal biomechanical stress and associated microdamage. A key event in the early stages of AS appears to be the association with subclinical Crohn's-like colitis with this gut inflammation being pivotal to the osteitis reaction. Read More

Evolving concepts of new bone formation in axial spondyloarthritis: Insights from animal models and human studies.

Best Pract Res Clin Rheumatol 2017 12 20;31(6):877-886. Epub 2018 Sep 20.

Division of Rheumatology, Toronto Western Hospital, University of Toronto, Toronto, ON, Canada; Krembil Research Institute, University Health Network, University of Toronto, ON, Canada.

New bone formation potentially leading to ankylosis of the sacroiliac joints and the spine is the main type of structural damage to the skeleton that characterizes axial spondyloarthritis. New data from animal models, imaging, and patient cohort studies support the view that sustained suppression of inflammation by therapeutic interventions can slow down the ankylosing process, at least in a large proportion of the patients. Although specific growth factor molecular signaling pathways are the key to drive the progenitor cell differentiation process that leads to ankylosis, inflammation plays an important role, most likely in combination with biomechanical and environmental factors, in both the onset and progression of the disease.

[Differential diagnosis of axial spondyloarthritis-axSpA mimics].

Z Rheumatol 2018 Oct 30. Epub 2018 Oct 30.

Rheumazentrum Ruhrgebiet, Claudiusstr 45, 44649, Herne, Deutschland.

The classification of axial spondyloarthritis (axSpA) comprises the classical ankylosing spondylitis (AS), which is characterized by already existing structural changes in the sacroiliac joints, and the so-called non-radiographic axSpA (nr-axSpA), in which by definition such changes are not present. This distinction is based on the ASAS classification criteria for axSpA, which are however not suitable for a diagnosis. According to the current classification, spondyloarthritis (SpA) includes axSpA, which can be associated with psoriasis and/or chronic inflammatory bowel diseases (CED), such as Crohn's disease and ulcerative colitis, and peripheral SpA, which is further divided into SpA associated with psoriasis, partially synonymous with psoriatic arthritis (PsA), reactive SpA, partially synonymous with reactive arthritis (ReA) and SpA associated with CED, partially synonymous with arthritis associated with CED (e.

Department of Orthopedics, Shandong Provincial Hospital Affiliated to Shandong University, Jinan, Shandong 250021, P.R. China.

Effects of minimally invasive plate-screw internal fixation and sacroiliac joint screw fixation in the treatment of posterior pelvic ring fracture were compared. Continuous selection of 20 cases of unstable pelvic posterior ring fractures, according to indications of operation, were divided into a group of 13 cases of plate-screw internal fixation and a group of 7 cases of sacroiliac joint screw fixation, and the operation effect and complications were compared. The comparisons of operation time, amount of radiation exposure, intraoperative blood loss, length of incision, partial load and full load time, and complications between two groups were carried out, and there were no statistically significant differences (P>0.

Imaging of axial spondyloarthritis. New aspects and differential diagnoses.

Clin Exp Rheumatol 2018 Sep-Oct;36 Suppl 114(5):35-42. Epub 2018 Oct 1.

Rheumazentrum Ruhrgebiet, Herne, Germany.

Axial spondyloarthritis (axSpA) is a chronic rheumatic disease characterised by inflammatory back pain and several other disease manifestations and comorbidities. The 2009 ASAS classification criteria differentiate between the classical ankylosing spondylitis or radiographic axSpA and non-radiographic axSpA based on the presence or absence of definite radiographic changes in the sacroiliac joints. Importantly, back pain in patients with axSpA may well have reasons other than axial inflammation or new bone formation. Read More
