 | | The suprascapular nerve arises from the lateral aspect of the upper trunk of the brachial plexus, runs across the posterior triangle of the neck together with the suprascapular artery and the omohyoid muscle, dips under the trapezius, and then passes through the suprascapular notch at the superior border of the scapula. |
 | | This almost 90-degree kink of the nerve often is exaggerated by a thickened ridge in the iliacus fascia as it attaches to the posterior aspect of the inguinal ligament. |
 | | To avoid kinking the nerve at both ends of the transposition, a block of the intermuscular septum is removed in the proximal end, and the aponeurosis and muscles fibers of the flexor carpi ulnaris are split longitudinally between the 2 heads. |
