Upon the inner side of the wound is the tendon of the flexorlongus hallucis along with, posteriorly, the muscular fibres of the abductor hallucis, 158 (1) Ist luiubrical m. hallucis m Peroneus ^longus tendon. j (2)Abductor hallucis m.

After cutting through this muscle the artery will be found lyingdeep at the first interosseous space where it joins the dorsal is pedis artery. Theartery lies upon the interosseous mu
