Figure 6: (a) Prone position for percutaneous endoscopic transforaminal discectomy under local anesthesia, (b) the entry point is marked along the horizontal line (c) and in lateral view, and vertical line. The guidewire then inserted through the spinal needle through the triangular working zone into the intervertebral disc with approximately a 45° angle (e). The tract is further sequentially dilated using dilators and then annulus is pierced once the tip of the trocar is confirmed at right space (f), (g) completeness of surgery is confirmed by flapping movement of the annulus (h) disc material
