The standard x-ray views of the shoulder include a true anterior-posterior view, a lateral (Y or outlet) view, and an axillary view. [13] A Velpeau view can be done as an alternative to the axillary view if an examinee is unable to position the shoulder for an appropriate image.
The shoulder joint has a very loose joint capsule, which can sometimes predispose the shoulder to dislocate. [citation needed] The "U shaped" dependent portion of the axillary part of the capsule ,located between the anterior and posterior bands of inferior glenohumeral ligament, is called "axillary pouch". [3]
Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1] A shoulder dislocation often occurs as a result of a fall onto an outstretched arm or onto the shoulder. [3] Diagnosis is typically based on symptoms and confirmed by X-rays. [2]
X-ray at right shows same shoulder after reduction and internal rotation, revealing both a Bankart lesion and a Hill-Sachs lesion. Diagnosis can be suspected by history and physical examination which is usually followed by imaging. Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers.
The light bulb sign is best observed on an AP radiograph of the shoulder. [5] Key features include: Rounded humeral head: The humeral head appears symmetrically rounded, resembling a light bulb due to internal rotation. Loss of normal glenohumeral overlap: The humeral head is posteriorly displaced, disrupting the alignment with the glenoid cavity.
Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
