Citation, DOI & article dataCitation: Murphy, A., Knipe, H. Shoulder (modified trauma axial view). Reference article, Radiopaedia.org. (accessed on 13 Sep 2022) https://doi.org/10.53347/rID-48955 The modified trauma axial view is a supplementary projection that replaces the ‘Y view’ of the two-view shoulder series. It is an orthogonal view of the AP projection of the glenohumeral joint and is often performed in the context of trauma. On this page:The modified trauma axial view is used to assess the articulations of the shoulder and the relationship of the humeral head with the glenoid. It is an optimal projection for possible scapulohumeral dislocations, glenoid fractures and Hill-Sachs defects 1, with a higher diagnostic yield than the lateral scapular shoulder view.
Slightly magnified (due to subject field distance). Clear visualization of the humeral head (with little to no superimposition) and its relationship with the glenoid of the scapula, in addition to the acromion and coracoid process This projection has been proven to be as diagnostically relevant as the lateral ‘Y’ view in trauma 2. Studies have shown that if it replaced the ‘Y’ view, no abnormalities would be overlooked. In trauma, this projection can be utilized on the supine patient with little to no effort on the patient's behalf, although it can get tricky with the subject-to-film distance and magnification. Remember to adjust your exposure in accordance with your angle; a steeper angle means the x-ray needs to penetrate through more tissue. The humeral head will be displaced superior to the glenoid if it is a posterior dislocation and inferior if it is anterior.

AP- Internal rotation.. Posterior oblique (Scapular Y) lateral.. Anterior oblique (Grashey method). What are the routine projections for a trauma shoulder?Routine radiographic projections for imaging of the acute shoulder include the AP with an additional projection; either a lateral of the scapula and proximal humerus (LS) or an axial projection of the shoulder. 2e4 The AP projection is a key component of the routine trauma shoulder series.
Where should the CR be located for an AP projection of the shoulder joint?Central ray: The central ray should be perpendicular to the image receptor directed to the glenoid fossa or 2 inches medial and 2 inches inferior to the superolateral border of the shoulder.
Which method and projection is used to demonstrate when chronic instability of shoulder is suspected?Radiography may show bone abnormalities associated to instability, including developmental and post-traumatic changes. CT is the best technique depicting and quantifying skeletal changes. MR-arthrography is the main tool in diagnosing the shoulder instability injuries.
