2. Figure 1
Posterior interosseous nerve (arrows) in the proximal segment, from the last motor bundle to the proximal edge of the dorsal retinaculum (1), and in the middle segment inside the fourth extensor compartment (2). In the middle segment, the PIN is embedded in a fibro-fatty sheath. The artery (star) is anterior and ulnar in most cases.
