Illustration showing the anterolateral and the posterolateral approach. The anterolateral approach to the distal part of the humerus (solid line) is made through the space between the extensor carpi radialis longus (ECRL) and the extensor carpi radialis brevis (ECRB) anteriorly, and between the ECRL-brachioradialis (BR) and the triceps posteriorly. The posterolateral approach to the distal part of the humerus (dashed line) is made through the space between the anconeus muscle and the ECRB anteriorly, and between these same structures and the triceps posteriorly. ECU = extensor carpi ulnaris, and EDC = extensor digitorum communis.
