Abstract

This study examined the anatomic location of the motor entry point (MEP) and branching point at the proximal and distal points of the tendon of the peroneal muscle by visual observation. Forty-three fresh legs of 25 adult bodies which had been donated to science were investigated in this study. The mean length of the reference line between the most proximal point of the head of the fibula (PHF) and the most distal point of the malleolus of the fibula (DMF) was 33.4 ± 2.5 cm. The MEPs of the peroneus longus (PL) and peroneus brevis (PB) gathered from 20 to 40% (7.0-13.0 cm) and 40 to 60%, respectively. The branching point where the nerve was divided to innervate the PL and PB was 10% and 28% from the PHF, respectively. These anatomic results suggest appropriate areas where to inject phenol or other agents for a MEP block in the case of a spastic lower extremity as well as guidelines for an electromyography conduction test.
