Placement of radio frequency-generated heat probes during a disc biacuplasty.

Disk biacuplasty is a medical procedure that applies heat to the annulus of disks that separate the vertebra of the back with the goal of ablating the neurons that generate pain sensations.[1] The procedure is designed to reduce chronic back pain caused by the intervertebral discs. The procedure is in the early stages of testing[2] with some evidence of efficacy.[3]

As possible advantages to conventional techniques, the developers of the procedure cite its ease of use and a lack of artificial concentric fissures. The procedure may destroy pain nerves without damaging nearby tissues, though evidence for this comes only from studies with cadavers.[1] Testing on pigs suggested it heats the desired area without damaging the dorsal root ganglia or spinal nerve roots, though the cells of the disc demonstrate histological changes.[4]
