The minimally invasive pedicle nail placement technique (METRX Quadrant) allows precise access to the surgical area by creating an expandable working channel without extensive muscle and soft tissue dissection, and smoothly performs all the complex operations that previously could only be done with traditional open surgery. The posterior lumbar structures are preserved as much as possible, reducing the damage to the lumbar back muscles, with less bleeding and less surgical trauma, which helps the patient to recover the lumbar function as soon as possible after surgery. This technique has wide application and can be applied to the surgical treatment of all lumbar degenerative diseases (including lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis, traumatic spinal fracture, etc.).
