n. pl. di·ar·thro·ses (-sēz)
Any of several types of bone articulation permitting free motion in a joint, as that of the shoulder or hip.

[Greek diarthrōsis, from diarthroun, to articulate : dia-, between; see dia- + arthroun, to fasten by a joint (from arthron, joint; see ar- in Indo-European roots).]

Sacroiliac joint is a diarthrodial synovial joint and a source of low back pain and referred pain in the lower extremity.1 The sacroiliac joint has been shown to be a source of pain in 10% to 27% of suspected cases with chronic low back pain.2 Compressive forces across the pubic symphysis are increased by activation of the obliqus internal (IO) and adductor longus, whereas activation of the IO, transverses abdominus (TrA), gluteus maximus, latissimus dorsi, and lumbar erector spinae increase compressive forces across the SIJ.3 Mooney, Pozos, Vleeming, Gulick and Swenski have also used EMG to validate the relationship between gluteus maximus and latissimusdorsi on the SIJ.
The existence of hyaline cartilage and a ligamentous system joining the two pieces corroborates the existence of at least a diarthrodial articulation.
These diarthrodial joints are formed by the articular facets of both the cricoid and arytenoid cartilages apposed in a multiaxial form.
Lumbar vertebrae with accessory diarthrodial articular facets, herein referred to as the articulating neural arch, in comparison, have recently been noted in three adult males.
The basic postulate for biomechanical development of the dysplastic trochlea is the Delpech law, according to which the cartilage of diarthrodial joints transfers decreased pressure and the neighbouring growth cartilage is in reverse proportional hyperactivity.
Rheumatoid arthritis (RA) is an autoimmune chronic disease characterized, among others, by pain, inflammation, and destruction of diarthrodial joints, resulting in functional disability [1].
The main pathological feature of RA is inflammation of the synovial membranes (Synovitis),with infiltration of T cells, B cells, macrophages, neutrophils, and synovial fibroblasts into the synovial compartment [2], mainly of diarthrodial joints [3].
Articular cartilage is an elastic connective tissue that covers the ends of bones in diarthrodial joints.
Autoimmune diseases (AIDs) are systemic inflammatory diseases that generally involve most of the organs in the body, such as the synovium of the diarthrodial joints.
Computational models of diarthrodial joint function depend on accurate reproduction of bony and soft tissue characteristics.
