Repeated peroneal nerve blocks can remarkably control sciatica leg pains in most cases and avoid the necessity of surgery
It has been known for some time that peroneal block can also block sciatica:
It’s application required weekly use and this was accomplished in a large study published in an obscure journal and ignored by fact journal is not accessible ( I had to buy a copy of the article).

One technique is quite simple – go 2 – 2.5 cm below fibular head, go straight down 1 cm through skin onto fibula, wait for paresthesias and inject 5 mls local.
I grip fibula, go down 2-2.5 cm from fibular joint, inject transversely from side, 5 mls of 2% lidocaine.
- 210 cases of L5 or S1 Radiculitis
- 35/210 needed 2 blocks to show effect
- Pain decreased from 2.99/4 to 0.91/4 – painkiller use was down by 2nd week
- Straight leg raising went from average 32 degrees before to 60 degrees after
- They felt: “A large number of cases, which would otherwise need surgery, could be easily managed by the use of a simple common peroneal nerve block”
Comment – have used it and found it surprisingly helpful where lower leg pain was involved. In sciatica, this leg pain came be very intense and this can relieve it for 3-7 days – whereapon one re-injects. Got to admit this is a lot cheaper then enbrel shots for sciatic pain. I am not sure this would work for cases where pain just referred to buttock.
