Topographic variations of the four main nerves at the axilla were found to be numerous, the most frequent arrangement being seen in less than two-thirds of the patients. Four separate nerves were seen on static ultrasound imaging at this sectional level of the axilla in only 78% of the cases.

The GIPM was seen in the majority undergoing ultrasound-guided femoral nerve blockade, even when the lateral part of the femoral nerve was not visualised. Using the lateral segment of GIPM as a target for needle tip location in an in-plane lateral to medial approach of the femoral nerve deserves further investigation.

Anatomical knowledge is of major importance for US-guided regional anaesthesia. US scan offers a new approach to anatomical variations of the vasculonervous bundle at the junction of the axilla and the upper arm.
