Fig. 2.

A longitudinal image of the proximal dorsal forearm. There were multiple constrictions of the PIN at the level of the distal end of the supinator muscle. The constrictions were bordered by swelling of the PIN (arrowheads)

Fig. 3.

A transverse image at the level of the distal end of the supinator muscle. A 27-gauge needle tip was guided adjacent to the PIN nerve and approximately 5 mL of 0.1% lidocaine solution was injected around the nerve (arrowheads). Hyperechoic bands were detached from the nerve

Fig. 4.

A longitudinal image of the proximal dorsal forearm 15 weeks after the first hydrodissection. The PIN appears quite swollen (arrowheads), but the multiple constrictions are no more evident
