Summary
This review examines clinical and biomechanical goals for disc arthroplasty, including pain relief and motion preservation. It assesses current devices against these criteria for nucleus and total disc replacement.
Area of Science:
- Spine surgery
- Biomedical engineering
- Orthopedics
Background:
- Spinal fusion is a common treatment for degenerative disc disease.
- Disc arthroplasty aims to provide an alternative with improved outcomes.
- Evaluating disc arthroplasty requires clear clinical and biomechanical criteria.
Purpose of the Study:
- To review the clinical and biomechanical objectives of disc arthroplasty.
- To assess available literature on nucleus and total disc replacement against these criteria.
- To report on current devices based on established criteria.
Main Methods:
- Literature review of clinical and biomechanical criteria for disc arthroplasty.
- Analysis of criteria for nucleus and total disc replacement.
- Evaluation of existing disc arthroplasty devices.
Main Results:
- Clinical criteria include pain relief, functional recovery, lower morbidity, shorter recuperation, and ease of implantation/revision.
- Biomechanical criteria include motion preservation, shock absorption, stress relief, stability, and alignment.
- The paper reviews devices in light of these comprehensive criteria.
Conclusions:
- Disc arthroplasty has defined clinical and biomechanical goals.
- Meeting these criteria is crucial for successful device development and patient outcomes.
- Further evaluation of devices against these benchmarks is warranted.
