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

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.

Background: Pelvic floor myofascial pain is common, but physical examination methods to assess pelvic floor muscles are poorly defined. We hypothesized that a simple, transvaginal pelvic floor examination could be developed that would be highly reproducible among providers and adequately screen for the presence of pelvic floor myofascial pain.

Pelvic osteomyelitis may occur in a metaphyseal equivalent, defined as a portion of flat or irregular bone that is adjacent to cartilage. The pelvic bone is known to have several metaphyseal equivalents and of these, the sacroiliac joint is the most frequent site of involvement. However, a sacral neurocentral synchondrosis has not been recognized as a metaphyseal equivalent, and there have been no previous reports describing this as the site of origin of sacral osteomyelitis.

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

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.

Spondyloarthritis (SpA) is a group of chronic inflammatory conditions which severely impact quality of life. Several criteria have been developed in the past to aid the diagnosis of SpA based on symptoms and radiographic changes during the course of the disease. However, it takes several years before structural changes manifest on conventional radiographs, leading to a diagnostic delay of 6 to 10 years. Read More

Juvenile spondyloarthritis may be present in at least 3 subtypes of juvenile idiopathic arthritis according to the classification of the International League of Associations for Rheumatology. By contrast with spondyloarthritis in adults, juvenile spondyloarthritis starts with inflammation of peripheral joints and entheses in the majority of children, whereas sacroiliitis and spondylitis may develop many years after the disease onset. Peripheral joint involvement makes it difficult to differentiate juvenile spondyloarthritis from other juvenile idiopathic arthritis subtypes. Read More

The term spondyloarthritis (SpA) encompasses a broad clinical spectrum characterized by chronic inflammatory conditions affecting the sacroiliac joints, the spine but also peripheral joints and tendons and being additionally associated with the involvement of organs, such as bowel, eye and skin (1). Musculoskeletal pain is a key symptom in SpA. However, although low back pain and/or joint pain are characteristic for SpA, undifferentiated pain at different enthesial sites may also be a concomitant or even the first clinical presentation in some patients (2).

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.

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
