🔍 Key Findings
- Integrated endoscopic mini-hemilaminectomy and lateral corpectomy was feasible at all targeted sites from T11–12 through L3–4.
- Target corpectomy dimensions were achieved or exceeded at every included intervertebral disc space.
- Median corpectomy dimensions were ~23% vertebral body length, ~47% body height, and ~74% vertebral canal diameter.
- Thoracic sites required a steeper learning curve, with early failures related to cannula positioning rather than drilling limitations.
- Angled positioning (30°–60° away from the surgeon) subjectively improved drill trajectory and facilitated horizontal corpectomy access.
- No rib head resection or rhizotomy was required to achieve target dimensions using the endoscopic system.
- Excellent visualization of nerve roots and spinal cord was achieved through the 23-mm endoscopic cannula.
- Incorrect intervertebral disc localization was the most common technical error, highlighting the value of intraoperative fluoroscopy.
