The V-Sign: A Simple Radiographic Sign of Shoulder Subluxation

“The Cliff Sign” - A New Radiographic Sign Of Hip Instability

Fallen lung sign: radiographic findings.

The term "fallen lung sign" refers to the collapsed lung in a dependent position, hanging on the hilum only by its vascular attachments. This is usually the result of the complete rupture of a bronchus. On chest radiograph, the diagnosis of bronchial tear is usually suspected with the persistence of a pneumothorax after chest tube insertion. An 8-year-old male patient had radiographic findings ...

Clinical evaluation of the shoulder shrug sign.

UNLABELLED The "shrug sign" (inability to lift the arm to 90 degrees abduction without elevating the whole scapula or shoulder girdle) has been associated with a diagnosis of rotator cuff disease. Based on our clinical experience, we hypothesized the shrug sign is not a specific diagnostic sign for this condition, but rather is associated with various shoulder conditions and shoulder weakness a...

A new physical sign in shoulder arthroscopy.

Arthroscopy is not as commonly performed at the shoulder as at the knee, but in both cases distension of thejoint by injection ofsaline is used to facilitate insertion of the arthroscope. At the knee the prominence of bony landmarks makes injection a simple procedure. The shoulder is deeply situated and more difficult to palpate, so that inadvertent injection of saline into the soft tissues aro...

Radiographic markers of acetabular retroversion: correlation of the cross-over sign, ischial spine sign and posterior wall sign.

Radiological diagnosis of acetabular retroversion is based on the presence of the cross-over sign (COS), the posterior wall sign (PWS), and prominence of the ischial spine (PRISS). The primary purpose of the study was to correlate the quantitative cross-over sign with the presence or absence of the PRISS and PWS signs. The hypothesis was that both, PRISS and PWS are associated with a higher cro...
