**3.4 Articular branch of lateral pectoral nerve (LPN)**

The articular branch or LPN crosses the superomedial side of the coracoid process [6, 11]. The US probe is placed between the inferior border of the clavicle and the superior border of the coracoid process. Below the deltoid muscle, the acromial branch of the thoracoacromial artery and, along with it, the nerve can be found (**Figure 10**).
