Since the disc is an avascular structure, it is an ideal environment for the growth of anaerobic bacteria. Propionibacterium acnes bacteria secrete propionic acid, which can dissolve fatty bone marrow and bone. Therefore, it was hypothesized that diffusion of propionic acid from the disc into the vertebrae results in bone oedema, i.e. Modic ...
Symptoms commonly include prolonged, inflammatory pain in the lower back region, hips or buttocks. [1] [4] However, in more severe cases, pain can become more radicular and manifest itself in seemingly unrelated areas of the body including the legs, groin and feet. [citation needed] Symptoms are typically aggravated by: [citation needed]
These may be unrelated to any symptoms and are just bulges of the anulus fibrosus. Jensen and colleagues, in an MRI study of the lumbar spine in 98 asymptomatic adults, found that in more than half, there was a symmetrical extension of a disc (or discs) beyond the margins of the interspace (bulging). In 27 percent, there was a focal or ...
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.
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]
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
It should not be confused with sciatica, a condition describing hip and lower back pain much more common to adults than transient synovitis but with similar signs and symptoms. Transient synovitis usually affects children between three and ten years old (but it has been reported in a 3-month-old infant and in some adults [3]). It is the most ...
The articular disc (or disk) is a thin, oval plate of fibrocartilage present in several joints which separates synovial cavities. This separation of the cavity space ...
