Overview
abstract
BACKGROUND CONTEXT: The XLP plate is an anterolateral instrumentation system developed as a part of the eXtreme Lateral Interbody Fusion (XLIF) system for lateral transpsoas interbody fusion, an alternative to anterior interbody fusion. PURPOSE: To report two cases of atraumatic coronal plane vertebral body fractures in the early postoperative period after interbody fusion using XLIF cages, lateral plating using the XLP plate, and unilateral posterior pedicle screw instrumentation. STUDY DESIGN: Case report. METHODS/SUMMARIES: Both patients were septuagenarian women with normal body mass indices and osteoporosis. The patients underwent L4-L5 XLIF with anterolateral instrumentation followed by posterior decompression and fusion using unilateral pedicle screws. In the early postoperative period (
