Transforaminal Endoscopic Decompression for Foot Drop 12 Years After Lumbar Total Disk Replacement

Abstract

Lumbar total disk replacement is considered for the treatment of lumbar degenerative disk disease with the hope that by preserving motion, the long-term fusion complication of adjacent segment disease can be avoided. The complications of lumbar total disk replacement can be divided into approach-related and long-term complications. Little has been described about the complications and treatment for complications >10 years after the device has been implanted. Here we describe a transforaminal endoscopic diskectomy procedure for a patient presenting with foot drop 12 years after a L5-S1 total disk replacement.
