18 Case Presentations and Surgical Technique: Percutaneous Endoscopic Lumbar Diskectomy: Central Transforaminal L2-L3 Protrusion
Clinical Findings
A patient presented with left lateral thigh and leg pain for 3 weeks.
VAS was 9/10 for left leg pain and 3 to 4/10 for back pain.
Sagittal and axial MRI and CT scan showed a soft central disk herniation at the L2-L3 level (Fig. 18.27).
Preoperative Plan
The skin entry point is selected by drawing various lines as shown in the axial MRI scan, and the distance from midline is ~10 cm (Fig. 18.28). This point is more lateral from the midline than in the case of a paramedian disk herniation of L2-L3.
