Objective:
Revision surgery for the removal of a migrated interbody fusion cage is challenging due to scar tissue formation in the surgical area. This study introduces a unilateral biportal endoscopic (UBE) technique for the removal of a migrated fusion cage and reports the patient's clinical outcomes.
Methods:
A unilateral lumbar interbody fusion (ULIF) was performed via a trans-facet approach to extract the posterior lumbar interbody cage, thereby bypassing scar tissue from prior surgeries.
Results:
The patient's clinical symptoms improved significantly postoperatively, with no complications such as nerve injury or cerebrospinal fluid leakage. At the six-month postoperative follow-up, the patient's lumbar and leg VAS scores showed significant improvement, with no obvious signs of cage loosening observed.
Conclusion:
UBE revision surgery may represent a safe and effective alternative for the removal of migrated posterior lumbar interbody cages.
