Study Design. Anatomic studies have demonstrated that nerves and blood vessels have
excursion with extremity range of motion. We have measured femoral nerve excursion with
the lateral lumbar transpsoas interbody fusion (LLIF) procedure with changes in table flexion
and ipsilateral hip flexion on both sides of 5 cadavers. Objective. To determine the effect of
hip range of motion on femoral nerve strain near the L4–L5 disc space because it pertains to
the LLIF procedure. Summary of Background Data. Postoperative thigh symptoms are …
