Introduction: Successful percutaneous endoscopic lumbar discectomy (PELD) requires an appropriate working trajectory. Due to the complexity of spinal anatomy, this is difficult to verify with conventional 2-dimensional fluoroscopy.

Aim: Here we assessed the feasibility and utility of the O-arm for establishing the working trajectory for PELD.

Material and methods: We retrospectively reviewed the records of 89 patients with lumbar disc herniation who underwent PELD using the O-arm. The working trajectory was evaluated with standard fluoroscopic images or 3-dimensional, volumetric computed tomography scan. Based on the detail provided by the multiplanar view, we confirmed the ideal working trajectory and adjusted the surgical approach accordingly.

Results: At the 12-month follow-up, based on MacNab’s criteria, 85.9% of patients showed an excellent or good outcome. There were no major complications.

Conclusions: The O-arm provides detailed multiplanar intraoperative high-quality imaging for PELD, and enables the surgeon to ascertain the surgical anatomy, determine the optimal working trajectory, and improve the accuracy of surgery.
