UBE surgery: Pay attention to details when operating on nerve roots

Pay attention to this type of nerve   

L4/5 segments will have different positions and routes for L5 roots. Simply divided into:

The horizontal type has a great risk during UBE surgical dissection or nerve root pulling, and is prone to nerve damage such as foot drop and numbness. The angle is horizontal and the emanation position is low, and there is a lot of tension and little movement. Therefore, traction can be detected intraoperatively or dissected from areas of low tension at the proximal epidural edge.
