Investigators found comparable implant failure and reoperation rates up to 2-year follow-up for minimally invasive corpectomy with percutaneously instrumented non-fused segments compared with open instrumented fusion.
Researchers identified 53 patients who underwent posterior thoracic corpectomies with cage reconstruction. Thirty-two patients underwent open corpectomy with instrumented fusion above and below the corpectomy site and 21 patients underwent mini-open corpectomy with percutaneous instrumentation without fusion. Overall, the mean follow-up was 29.2 months. Investigators found the overall perioperative complication rate was 15.1%. Although patients who underwent open corpectomy had higher complication raters vs. patients who underwent a mini-open corpectomy, this difference was not statistically significant. Investigators noted the mean length of hospital stay was 10.5 days. Patients who underwent an open corpectomy had a significantly longer hospital stay compared with patients who underwent a mini-open corpectomy. At 6 months, 1 year and 2 years, the overall implant failure rates necessitating reoperation were 1.9%, 9.1% and 14.7%, respectively. The reoperation rates were not significantly different between the two groups. – by Monica Jaramillo
