Whereas standard anterior approaches for thoracolumbar corpectomies have commonly been used, the transpedicular technique is increasingly used to perform corpectomies from a posterior approach. The authors conducted a study to analyze whether there was a difference in outcomes by comparing transpedicular corpectomies to standard anterior thoracolumbar corpectomies.


The senior author performed thoracolumbar corpectomies in 80 patients between 2004 and 2008. The authors reviewed medical records and follow-up data, consisting of clinic visits, radiographs, or telephone interviews. Neurological outcome, complications, operative times, revision surgery rates, and estimated blood loss (EBL) were evaluated.


Thirty-four patients underwent transpedicular corpectomies, and 46 patients underwent anterior thoracolumbar approaches. Single-level transpedicular corpectomies appear to be comparable to anterior-only corpectomies in terms of EBL, operative time, and complication rates. There was a higher complication rate, increased EBL, and longer operative time with anterior-posterior corpectomies compared with transpedicular corpectomies. Patients undergoing transpedicular corpectomies had a greater recovery of neurological function than those in whom anterior-approach corpectomies were performed.


The transpedicular corpectomy appears to have a comparable morbidity rate to anterior-only corpectomies, but its morbidity rate is lower than that of anterior-posterior corpectomies.
