Summary
Lessons from extremity joint replacement can help anticipate challenges with new lumbar disc arthroplasty. Studying past experiences may accelerate the learning curve for this motion-preserving spinal device.
Area of Science:
- Spine surgery
- Arthroplasty
- Biomedical engineering
Background:
- Emerging disc arthroplasty designs generate clinical anticipation.
- Adoption of new spinal technologies presents inevitable challenges.
- Extremity arthroplasty experience may offer insights into motion-preserving spinal devices.
Purpose of the Study:
- Review extremity total joint literature for transferable lessons.
- Anticipate predictable problems with lumbar disc arthroplasty.
- Apply lessons from extremity arthroplasty to spinal applications.
Main Methods:
- Literature review of extremity total joint arthroplasty.
- Conjectural analysis of anterior lumbar interbody fusion (ALIF) device experience.
- Application of lessons learned to lumbar disc arthroplasty.
Main Results:
- Limited data currently exist for disc arthroplasty.
- Controversies and uncertainties surround disc arthroplasty.
- Ongoing Investigational Device Exemption (IDE) clinical trials will provide further insight.
Conclusions:
- Complications are expected in disc arthroplasty.
- Complications may be related to surgical approach, device design, or patient selection.
- Extremity joint arthroplasty experience can accelerate the learning curve for lumbar disc arthroplasty.
