A practical laboratory study simulating the percutaneous lumbar transforaminal epidural injection: training model in fresh cadaveric sheep spine.

摘要

Laboratory training models are essential for developing and refining treatment skills before the clinical application of surgical and invasive procedures. A simple simulation model is needed for young trainees to learn how to handle instruments, and to perform safe lumbar transforaminal epidural injections. Our aim is to present a model of a fresh cadaveric sheep lumbar spine that simulates the lumbar transforaminal epidural injection. MATERIAL andThe material consists of a 2-year-old fresh cadaveric sheep spine. A 4-step approach was designed for lumbar transforaminal epidural injection under C-arm scopy. Results: For the lumbar transforaminal epidural injection, the fluoroscope was adjusted to get a proper oblique view while the material was stabilized in a prone position. The procedure then begin, using the C-arm guidance scopy.The model simulates well the steps of standard lumbar transforaminal epidural injections in the human spine. The cadaveric sheep spine represents a good method for training and it simulates fluoroscopic lumbar transforaminal epidural steroid injection procedures performed in the human spine.
