Samartzis and colleagues describe a unique 1-stage technique for total spondylectomy of a lumbar GCT with short segment reconstruction. Although the results are impressive, the short segment instrumentation with pedicle reconstruction seems controversial. Because there is no immediate anterior fixation, exactly what is the benefit biomechanically of pedicle reconstruction both before and after the arthrodesis of the anterior graft? The importance of precise pedicle screw placement and the patient having good bone quality is obvious.

Samartzis and colleagues describe a unique 1-stage
technique for total spondylectomy of a lumbar GCT with
short segment reconstruction. Although the results are
impressive, the short segment instrumentation with pedicle
reconstruction seems controversial. Because there is no
immediate anterior fixation, exactly what is the benefit
biomechanically of pedicle reconstruction both before and
after the arthrodesis of the anterior graft? The importance of
precise pedicle screw placement and the patient having good
bone quality is obvious.
