Age at nerve lesion in years. Interval block 1 and lesion in months. Effects of the lidocaine or saline injection: 0) No effect; 1) Pain relief for several hours; 2) Pain relief for days or permanent pain relief; 3) Increase of pain for hours or days. Result of surgery: 0) no effect, 1) partial pain reduction, 2) (as good as) pain free, 3) temporary pain reduction, 4) increase of pain as compared to the pre-operative level.

* Permanent pain relieving effect as response to the block
