Patient Presentation and Clinical Evaluation The procedure was carried out using an advanced endoscopic technique, allowing precise decompression of neural elements and stabilization of the affected spinal segment while preserving surrounding musculature. The surgical approach required only a small skin incision of approximately 1–2 cm, resulting in minimal muscle disruption, reduced blood loss, and decreased postoperative pain compared to conventional open surgery. Minimally invasive spine surgery. Postoperatively, the patient demonstrated a remarkable improvement in both pain levels and functional capacity. She experienced early mobilization and a faster recovery, enabling her to resume daily activities with significantly reduced discomfort. The overall surgical outcome was highly satisfactory, highlighting the effectiveness and advantages of endoscopic TLIF as a minimally invasive treatment option for L4–L5 spondylolisthesis.
