The curved needle technique for accessing the L5/S1 disc space

Bending the guide needle has been suggested as an alternative technique that may improve the success rate for accessing the L5/S1 level on discography. We performed a prospective randomized study to compare this technique with the use of a conventional straight needle. There was a significantly lower failure rate using the curved needle (p < 0.05). The incidence of nerve root impingement was also lower.
