**3.6 Pronator teres (PT)**

The child should be supine or sitting as per convenience and cooperation with the forearm in supine. Take the midpoint of the elbow flexor crease and also mark the

lateral and medial points. Now, bisect the medial and mid-elbow crease points. Now, mark a point 1–2 cm distal to this point (medial one-fourth). Now place the index finger in the antecubital fossa, just medial to the index finger is pronator teres at the final mark point. Now, try to stabilize PT with the index finger and thumb, and confirm it by doing prono-supination. Now, insert the needle into it and again reconfirm the needle movement. If one is more medial and distal might inject into flexor carpi radialis, sometimes into flexor digitorum superficialis (**Figure 15**).
