Cervical disc arthroplasty (CDA) utilization in Australia remained stable from 2019-2024, with most procedures performed on patients aged 35-54. This analysis provides insights into current adoption trends for this motion-preserving spinal surgery.
Area of Science:
- Spine surgery
- Orthopedics
- Neurosurgery
Background:
- Cervical disc arthroplasty (CDA) offers motion preservation and may reduce adjacent segment disease compared to fusion.
- Limited data exists on the clinical practice uptake of CDA.
Purpose of the Study:
- To analyze Australian population trends in CDA utilization over a 6-year period (2019-2024).
Main Methods:
- Analysis of the Medicare Benefits Schedule (MBS) database for CDA procedures in adult patients.
- Data stratified by sex and year, with population adjustments.
Main Results:
- 4216 CDA procedures were performed between 2019 and 2024.
- Procedure volumes were stable from 2019-2021, then declined.
- The 35-54 age group accounted for the majority of procedures (62.28%).
Conclusions:
- CDA utilization in Australia has remained stable, with highest uptake in young to middle-aged adults.
- Further research into factors influencing CDA adoption is warranted.
