Total anterior load transfer with a cortico-pedicular posterior fixation (CPPF) device, pedicle screw system (PSS), and intact spine. Anterior loading between PSS and CPPF is reported across four instrumented spinal levels from three separate finite element analysis models including single-level lateral lumbar interbody fusion (LLIF) with PSS or CPPF (1 level), two-level LLIF with PSS or CPPF (2 levels), and single-level anterior lumbar interbody fusion (ALIF) with PSS or CPPF (1 level)
