Laboratory training models are so essential to develop and refine surgical skills before spinal surgery’s clinical application. A simple simulation model for young residents can help you learn how to handle the instruments and perform safe posterior lumbar approaches. The researchers aimed to prepare a practical laboratory model using a fresh sheep lumbar spine that controls the pedicular screw fixation during spine surgery. The material was a fresh cadaveric spine taken from a 2-year-old sheep. A two-step approach was designed for posterior lumbar approaches, including placement of lumbar pedicular screws.

The model showed that the standard posterior lumbar pedicular screw fixation of the human spine could be under simulation. The cadaveric sheep spine represents a new-way method to accustom trainees of neurosurgery and spine surgery residents and stimulates posterior lumbar pedicular screw fixation performed in the human spine. The doctors and researchers are still looking for some more effective models that can easily simulate standard posterior lumbar pedicular screw fixation of the human spine. They take every document and data into consideration to find out some better outcomes from this pedicular screw fixation during spine surgery. That will bring a new dimension in this field.
