A practical laboratory study simulating the lumbar microdiscectomy: training model in fresh cadaveric sheep spine

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Surgical Education

Background:

• Surgical training models are crucial for developing proficiency in spinal surgery.
• Young residents require accessible simulation tools for mastering lumbar approaches and instrument handling.
• Existing models may not adequately replicate the nuances of human lumbar microdiscectomy.

Purpose of the Study:

• To introduce a cost-effective and practical laboratory model for simulating lumbar microdiscectomy.
• To utilize a fresh sheep lumbar spine for realistic surgical training.
• To facilitate the learning curve for residents performing posterior lumbar microdiscectomy.

Main Methods:

• A fresh cadaveric lumbar spine from a 2-year-old sheep was used.
• Surgical procedures mimicking human lumbar microdiscectomy were performed.
• Procedures were conducted under the magnification of an operating microscope.

Main Results:

• The sheep lumbar spine model allowed for the simulation of key surgical steps in lumbar microdiscectomy.
• The model provided a tangible platform for residents to practice instrument manipulation.
• The anatomical characteristics of the sheep spine proved suitable for replicating posterior lumbar approaches.

Conclusions:

• The fresh cadaveric sheep lumbar spine is a valuable and practical training model for posterior lumbar microdiscectomy.
• This simulation model aids in developing essential surgical skills for residents.
• It offers a reproducible method for training safe lumbar surgical techniques.
