(accessed on 08 Sep 2022) https://doi.org/10.53347/rID-52966 The inferosuperior axial view also known as a Lawrence view of the shoulder is a modified axial projection best utilized with supine patients. It is an orthogonal projection to the AP view and replaces the lateral shoulder projection. On this page:It is an appropriate projection to assess suspected dislocations, proximal humerus pathology and effective in demonstrating the articular surfaces of the humeral head and glenoid 1-3 . Hill-Sachs lesions are well demonstrated on this projection along with the lesser tubercle of the humerus. This view is performed when the patient can only lie supine; thus making the superior-inferior axial view difficult to achieve. This view provides additional information for assessing dislocations and glenohumeral instability; particularly if these are not seen well on a standard AP view 4.
Clear visualization of the humeral head (with no superimposition) and its relationship with the glenoid of the scapula. In addition to the acromion and the coracoid process. The lesser tubercle should be seen projected anteriorly in profile. The coracoid process is pointing anteriorly This is an ideal projection when patients are unable to move from the supine position. It can cause patient pain when abducting but nowhere near as much as the standard axial projection. Be wary of your surroundings when moving the x-ray tube in position, there is a high potential of hitting the patients feet. Other projections suitable for supine patients that require an orthogonal view of the AP view include:

The inferosuperior axial projections (Lawrence and West Point methods) require the patient to be in a recumbent position with the arm abducted.
What is Inferosuperior projection?The inferosuperior axial view also known as a Lawrence view of the shoulder is a modified axial projection best utilized with supine patients. It is an orthogonal projection to the AP view and replaces the lateral shoulder projection.
What is the Lawrence method?The Lawrence1 method is used when trauma exists, and the arm cannot be rotated or abducted because of an injury. This projection shows the proximal humerus in a 90-degree projection from the AP projection and shows its relationship to the scapula and clavicle.
