Purpose:
To provide an updated analysis of perioperative complications, patient demographics, and surgical techniques in spinal surgeries across Japan and examine their impact on risk management.
Methods:
Data were collected prospectively from 739 of 1,106 registered facilities across Japan using the JSSR database. All spinal surgeries conducted in November 2021 were included, capturing complications within 1 month post-surgery. Data analyzed included patient demographics, disease classification, surgical techniques, site, approach, and complications. Descriptive statistics determined complication rates and trends.
Results:
The survey included 11,559 surgeries (average patient age: 67.0 years). Degenerative diseases comprised 71.0% of cases. Posterior surgical approaches were predominant (87.9%), and minimally invasive techniques were widely adopted. The overall complication rate was 8.8%, with dural tears (2.4%) being the most common. Minimally invasive techniques improved outcomes but posed technical challenges, highlighting the need for advanced training and equipment.
Conclusion:
Japan's aging surgical population and the adoption of minimally invasive techniques are evident. While complication rates remain stable, specific complications such as dural tears require targeted management. These findings underscore tailored surgical strategies for older patients and innovation in techniques, providing critical evidence for improving outcomes and informing healthcare policy in Japan.
