Intra-articular bodies in SOC typically have popcorn calcification, with a dense sclerotic border with radiolucent central region. This distinct radiographic appearance sets it apart from other causes of intra-articular bodies. Number and size of intra-articular bodies can prove helpful as well.
An articular cartilage defect that initially may be small still has the potential to have a physical and chemical "domino effect" on the surrounding "normal" articular cartilage. [2] Pitkin et al. (2014) discovered a potential etiology for articular cartilage damage. When the interarticular transmission of pressures is interrupted so that ...
Proton density weighted MRI of a knee with synovial chondromatosis. There are multiple intra-articular loose bodies located in the suprapatellar recess. [5]Diagnosis is by medical imaging; X-ray, CT scan and MRI. [1]
The causes of intra-articular snapping hip syndrome seem to be broadly similar to those of the extra-articular type, but often include an underlying mechanical problem in the lower extremity. The pain associated with the internal variety tends to be more intense and therefore more debilitating than with the external variety. [4]
True locking happens when the intra-articular structure (e.g. ligaments) [1] is damaged, or a loose body is present inside the joint, or there is a meniscal tear. The knee can be unlocked by rotating the leg and full movement can be restored. A person may feel the presence of a loose body in the suprapatellar region or lateral and medial gutter.
However, osteophytes on the spine can impinge on nerves that leave the spine for other parts of the body. This impingement can cause pain in both upper and lower limbs and a numbness or tingling sensations in the hands and feet because the nerves are supplying sensation to their dermatomes .
Femoroacetabular impingement (FAI) is a condition involving one or more anatomical abnormalities of the hip joint, which is a ball and socket joint. [1] It is a common cause of hip pain and discomfort in young and middle-aged adults. [2]
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
