Of these limbs, an aberrant origin of the suprascapular artery from the first part of the axillary artery (Figure 2) was detected in only one limb, constituting 3.6% of this sample. Both nerve and artery passed beneath the transverse scapular ligament anomalously (Figure 2) and thereafter the artery entered the supraspinous fossa where it irrigated the supraspinatus muscle and took part in the anastomosis around the scapula.
