ABSTRACT
BACKGROUND AND OBJECTIVES:
The ability to maximize corpectomy cage endcap size and vertebral endplate coverage after corpectomy for lumbar burst fractures (L1-L5) is limited by the presence of lumbar nerve roots and the larger cross-sectional area of the lumbar endplates relative to the restrictive corridor for cage insertion. This work aims to provide details and clinical examples of a novel operative technique for 3-column reconstruction and stabilization of comminuted lumbar burst fractures.METHODS:
Through a standard posterior midline approach and following posterior instrumentation and lateral extracavitary corpectomy, an in-situ assembly of a modular corpectomy cage that respects adjacent neural structures, restores segmental alignment, and maximizes endplate coverage across a lordotic segment is completed.RESULTS:
Radiographic evidence of anatomic spinal reconstruction and stabilization with complete or near-complete endplate coverage without incurrence of new clinical deficit after this novel treatment of lumbar burst fractures.CONCLUSION:
The fixation approach described in this report may be a valuable modification to a long-standing technique used for treating comminuted lumbar burst fractures (L1-L5) from a posterior-only approach without incurring additional neurological deficits and by improving endplate and apophyseal ring coverage.
