The radiographic modalities discussed in this article are useful adjunctive techniques in the evaluation of arthritic disease. None of these modalities should be considered for baseline study. Rather, they should be considered following plain film examination when further information is required. The one modality that may be considered for a screening examination is radionuclide imaging. It is most useful when early diagnostic information regarding the extent of pathology is required. A pattern of activity can provide important information to the clinician, enabling an accurate diagnosis. Arthrography is best reserved for the evaluation of articular cartilage of a particular joint. A double-contrast arthrogram should be performed in this case. The technique has little application in the evaluation of polyarticular disease. Tenography is most useful in differentiating tenosynovitis from stenosing tenosynovitis. The differentiation is important because a diagnosis of stenosing tenosynovitis usually necessitates surgical intervention. Spontaneous rupture can be evaluated with tenography, but is is probably best evaluated with MRI. CT may be used in the evaluation of both soft-tissue and articular pathology. It is perhaps best employed in the evaluation of articular pathology of the rearfoot. This technique should not be used as a screening examination for vague foot pain. MRI is the newest and most exciting imaging modality available. The excellent soft-tissue contrast provides an accurate means of evaluating the extraarticular manifestations of arthritic disease. MRI may aid in differentiating rheumatoid nodules from neuromas in rheumatoid patients with excessive forefoot disease. It is also useful in the evaluation of tendon pathology, particularly spontaneous ruptures. This technique is only in its infancy, but technologic advances are rapidly making it a major force in the field of diagnostic imaging.

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune inflammatory diseases, with a progressive etiology that results in serious complications and a higher chance of early death. Visfatin, an adipokine, is correlated with disease pathologic features and becomes a key biomarker and therapeutic target for RA. This study aimed to evaluate the anti-arthritic activity of metformin (an antidiabetic drug with anti-inflammatory activities) and methotrexate (the first choice for disease-modifying antirheumatic drugs in RA, with diverse adverse effects) in complete Freund's adjuvant (CFA)-induced arthritis in female rats.

Spondyloarthritis is a prevalent and persistent condition that significantly impacts the quality of life. Its intricate pathological mechanisms have led to a scarcity of animal models capable of replicating the disease progression in humans, making it a prominent area of research interest in the field. To delve into the pathological and physiological traits of spontaneous non-human primate spondyloarthritis, this study meticulously examined the disease features of this natural disease model through an array of techniques including X-ray imaging, MRI imaging, blood biochemistry, markers of bone metabolism, transcriptomics, proteomics, and metabolomics.

The excessive proliferation of fibroblast-like synoviocytes (FLS) leads to synovial hyperplasia, a key pathological hallmark of rheumatoid arthritis (RA). Eupalinolide B (EB), a sesquiterpene lactone of Eupatorium lindleyanum DC., has anti-inflammatory effects and anti-proliferative activity in tumor cells.

Background: The temporomandibular joint (TMJ) is a unique joint that enables mandibular movement. Temporomandibular diseases (TMDs) impair joint function, leading to more or less specific clinical signs.
Objectives: To compile and disseminate clinical data and research findings from existing publications on equine TMD.

Introduction: Osteoarthritis (OA) is a degenerative joint disease that can affect the many tissues of the joint. There are no officially recognized disease-modifying therapies for clinical use at this time probably due to a lack of complete comprehension of the pathogenesis of the disease. In recent years, emerging regenerative therapy and treatments with stem cells both undifferentiated and differentiated cells have gained much attention as they can efficiently promote tissue repair and regeneration.
