Clinical Implications of Vertebral Endplate Disruptions After Lumbar Discectomy: 3-Year Results from a Randomized Trial of a Bone-Anchored Annular Closure Device.

ABSTRACT:

Objective

Vertebral endplate disruptions (VEPD) are common findings on imaging after lumbar surgery. The objective of this study was to explore the clinical implications of VEPD development following lumbar discectomy with or without implant with a bone-anchored annular closure device (ACD).

Methods

This was a multicenter randomized controlled trial of patients with large postsurgical annular defects after limited lumbar discectomy who were randomized to additionally receive an ACD or no additional treatment. VEPD were identified on computed tomography and confirmed by an imaging core laboratory. Clinical outcomes included recurrent herniation, reoperation, Oswestry Disability Index, leg pain, and back pain. Patient follow-up in this study was 3 years.
