forearm. However, with the arm pronated, it transverses the fore-

arm. L.I.-7lies on the dorso-lateral aspect of the radius and is

best located with the forearm in midposition and the elbow

flexed. Spreading hands technique: Place the little fingers on

➞L.I.-5and ➞L.I.-11and span the hands evenly so that the

thumbs join at the midpoint of the line. From there, measure

1 cun distally. ➞T.B.-8is located 4 cun proximal to the wrist

crease between the radius and the ulna in the centre of the dorsal

forearm or 1 cun distal to L.I.-7.
