Treatment is difficult, often requiring a joint replacement. [citation needed] Spontaneous improvement occasionally happens and some juxta-articular lesions do not progress to collapse. [citation needed] Other treatments include immobilization and osteotomy of the femur. [citation needed] Cancellous bone grafts are of little help. [citation needed]
A bone scan or MRI may be useful in making the diagnosis in those cases where X-rays are inconclusive. Usually, plain radiographic changes are delayed six weeks or more from clinical onset, so bone scintigraphy and MRI are done for early diagnosis. MRI results are more accurate, i.e. 97–99% against 88–93% in plain radiography.
Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high-dose steroids. [1] The condition may also occur without any clear reason. [1] The most commonly affected bone is the femur (thigh bone). [1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1]
The type of contrast injected into the joint depends on the subsequent imaging that is planned. For pneumoarthrography, gas is used, for CT or radiographs, a water-soluble radiopaque contrast, and for MRI, gadolinium. Double-contrast arthrography can be used for more anatomically complex cases, though its use is relatively infrequent.
A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis). [1]
The injury is caused by harsh contact, the type often associated with sports. It occurs at the iliac crest − the bone that sticks out of the side − of the hip. The injury often doesn't last ...
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. [5] [6] It is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. [7]
A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [3] It is an injury of the anterior glenoid labrum of the shoulder. [4] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
