Ultrasound Lancet-aided Translaminar Posterior Lumbar Approach to the Recesso-Foraminal Area: Technical Note.

Extrusion and sequestration of the nucleus pulposus involving the spinal canal or the foramina/recesses complicates up to 28% of the lumbar disc herniations. The transpars/translaminar anatomical approach is well described and its advantages when handling with a lateral, foraminal extruded disc herniation are appreciated and recognized. Nevertheless, this approach presents several pitfalls such as the risk of disconnecting the pars interarticularis, which may cause segmental instability. This particular eventuality is because of the particular anatomical conformation of the pars interarticularis. Although already part of the modern surgical armamentarium for general, orthopedic, cranial and spinal surgeons, the use of the ultrasonic scalpel technique for such approach has never been discussed to date, to the best of our knowledge. The purpose of the present paper is therefore to introduce and describe the stepwise technique along with an extensive discussion of the facilitating role of the ultrasonic scalpel in the translaminar/transpars approach in the management of extruded disc herniation of the lumbar spine.
