Table 1. Effect of Sham Procedure on Naive and Neuropathic Animals

Control experiments: Pain sensitivity assessment 1 week after the different procedures in naive and SNI animals and their respective sham-operated controls to prove the harmlessness of the block surgery technique without bupivacaine microspheres. No difference due to the sham procedure was observed in naive or SNI rats (n = 4 in each group).

SNI = spared nerve injury.
