This is the gold standard view for the . The axial angle separates the distal clavicle from the acromion, allowing you to see subtle widening (separations) or arthritis that gets hidden on frontal views.
Standard axial views require the patient to lift their arm to nearly 90 degrees. When trauma prevents this, the following alternatives are used: Velpeau View:
Posterior shoulder dislocation | Radiology Reference Article
This view provides a bird’s-eye look at the coracoid. It is excellent for detecting coracoid fractures or identifying a type III coracoid that might be causing subcoracoid impingement. half axial view shoulder
The patient remains in a shoulder sling and leans back approximately 30 degrees while seated or standing. The X-ray beam passes vertically through the joint, providing an axial perspective without moving the injured limb. Modified Trauma Axial (MTA):
Patients with adhesive capsulitis have severe restriction in abduction and external rotation. The half axial view allows imaging without forcing the joint into a painful position.
It clearly demonstrates the "golf ball on a tee" relationship of the joint, ensuring the humeral head is properly centered. Positioning Techniques This is the gold standard view for the
The "half axial" or is a specialized shoulder X-ray projection used primarily to assess the relationship between the humeral head and the glenoid cavity when a patient cannot perform standard movements due to pain or injury . Key Helpful Features
The radiologist notes that the humeral head looks slightly symmetrical but the joint space on the AP view is intact. The patient, however, cannot externally rotate his arm.
, are essential in trauma settings to assess glenohumeral alignment. Radiopaedia Common "Half Axial" Variations When trauma prevents this, the following alternatives are
(fractures of the anterior-inferior glenoid rim). Displacement or angulation in proximal humeral fractures . Comparison to Other Axial Views
In many trauma cases, patients cannot lift their arms into a traditional axillary position due to intense pain or physical blockage from a dislocation. The half axial view is specifically designed for these scenarios. It allows radiologists to:
