In May, Spine published an article from the Texas Back Institute (Plano TX) on a large consecutive clinical case series that demonstrated a 1.26% removal/revision rate with 2,141 lumbar total disc replacement (TDR) patients since the year 2000. This retrospective study includes multiple different lumbar TDR devices and represents more long-term clinical evidence that supports the efficacy of the lumbar TDR procedure.
Please share the link to the study abstract with surgeon customers interested in learning more about long term lumbar TDR outcomes. This may be especially useful for surgeons concerned about lumbar TDR safety and durability over time, and the potential need for device removal or revision.
Key Takeaways from the Published Study:
- In a large consecutive series of 2141 patients who underwent lumbar total disk replacement during a 20-year period, the rate of device removal or revision surgery was 1.26%.
- There was no indication of an increasing rate of removals/revisions with increasing follow-up duration.
- This data supports the safety and durability of lumbar total disk replacement implants.
- The low rate of removal/revision over a 20-year period provides reassurance in the safety of lumbar arthroplasty in appropriately selected patients.
ARTICLE DETAILS
Title:
Lumbar Total Disk Replacement Device Removals and Revisions Performed During a 20-Year Experience with 2141 Patients.
Authors:
Richard Guyer, MD, Scott Blumenthal, MD, Jessica Shellock, MD, Jack Zigler, MD, Donna Ohnmeiss, PhD.
Study Design:
Retrospective study with prospective patient contact attempted to collect current data.
Study Objective:
To investigate the incidence and reasons for lumbar total disk replacement (TDR) removal/revision in a large consecutive series of patients during a 20-year period at a single institution.
Background:
A concern regarding lumbar TDR was safety and durability over time, particularly the need for device removal or revision. This may be particularly important considering removal/ revision requires repeat anterior exposure with an increased risk of vascular injury.
Methods:
Data were collected for 2141 lumbar TDR patients, beginning with the first case in 2000. The mean follow-up was 78.6 months. For each case of device removal/revision, the reason, duration, and procedure performed were recorded.
