“…Similar to other synovial joints, osteoarthritis of the atlanto-dental joint involves various changes, including narrowing of the joint space, marginal cortical thickening, ligamentous calcification, and vacuum phenomenon (1)(2)(3)(4), and these changes are displayed more clearly by CT than by a lateral cervical radiographic projection (5). At radiography or autopsy, 80-88% of atlanto-dental joints in adults aged >60 years old were degenerative, and osteoarthritis appeared after 30 years of age (6).…”

The Diagnostic Value of the Vacuum Phenomenon during Hip Arthroscopy

The diagnostic value of the vacuum phenomenon between the femoral head and the acetabulum, and time frame of its occurrence after application of traction is an important clinical question. The resulting arthrogram may outline the shape, location, and extent of cartilage lesions prior to arthroscopy of the hip joint. The presence, duration, and diagnostic information of the vacuum phenomenon were evaluated in 24 hips that underwent arthroscopy. The operative diagnosis was compared to the results of imaging studies and to findings obtained during a traction trial prior to arthroscopy. Indications for arthroscopy included avascular necrosis, labral tears, loose bodies, osteoarthrosis, and intractable hip pain. In 22 hips the vacuum phenomenon developed within 30 seconds after application of traction. The most important data obtained from the vacuum phenomenon was the location and extent of femoral head articular cartilage detachment and the presence of nonossified loose bodies. The vacuum phenomenon did not reveal labral or acetabular cartilage pathology in any of these patients. The vacuum phenomenon obtained during the trial of traction can add valuable information prior to hip arthroscopy. Femoral head articular cartilage detachment was best documented by this method. The hip arthroscopist should utilize this diagnostic window routinely prior to hip arthroscopy.

“…The presence of gas within a joint space was first described by Fick in 1910, and subsequently, it was reported in the intervertebral disc, pubic symphysis, peripheral synovial joints with open injury, with the traction of the joints as in hip, with infective spinal causes, non-open injury as in ankle and temporomandibular joint (TMJ), and mostly with degenerative changes in all the joints [2][3][4][5][6][7][8]. Although routine radiographs have been mainly used to demonstrate vacuum phenomenon, other modalities such as ultrasonography (USG), CT scan (CT), and MRI can better delineate the air shadow.…”

The Air Inside Joint: A Sign of Disease Pathology or a Benign Condition?

Vacuum phenomenon' or 'pneumoarthrosis' term is used when there is air within a joint space. It has been described commonly in the spine and occasionally in the peripheral articulations. It is usually seen following trauma, and sometimes spontaneously in joints showing degenerative changes. Although it has been mainly described with a conventional radiograph, other diagnostic modalities such as ultrasonography, CT scan, and MRI have also been used for its delineation. We present three cases of vacuum phenomenon observed in the shoulder joints and the hip joint. These radiolucent shadows were visible in the radiograph and vanished subsequently. The 'air inside the joint' may be a benign condition and does not necessitate further workup unless the patient is symptomatic.
