The purpose of this study is to investigate the change in biomechanical milieu following removal of pedicle screws in instrumented single level lumbar arthrodesis. Using a validated finite element (FE) model of the intact lumbar spine (L2–5), two scenarios of L3–4 lumbar fusion were simulated: posterolateral fusion (PLF) at L3–4 using pedicle screws (PLF with pedicle screws; WiP) and L3–4 lumbar posterolateral fusion state after removal of pedicle screws (PLF without pedicle screws; WoP).
