Regional Blockade of the Shoulder: Approaches and Outcomes

Figure 9

Anatomic representation of the Price technique. The horizontal axis (H) lies at the level of the quadrilateral space, where the axillary nerve passes beneath the glenohumeral joint capsule. The interception of the vertical axis (V) with the horizontal axis (H) allows location of the axillary nerve as it crossing the posterior neck of the humerus (Price [3]). (Reprinted with permission.)
