Histological Consequences of Needle-Nerve Contact following Nerve Stimulation in a Pig Model
Figure 2
(a) Needle tip to nerve contact following needle placement with low threshold current (0.2 mA). The needle tip is located adjacent to nerve epineurium. (b) Distant needle placement with high threshold current (1.0 mA). A needle tip to nerve proximity of 2 mm was measured. N, radial nerve.
