| アブストラクト | PURPOSE: This study investigates Japanese trends in Open Reduction and Internal Fixation (ORIF) surgeries for acetabular and pelvic fractures, focusing on age, gender, regional disparities, and how orthopedic surgeon distribution affects surgical volumes, aiming to identify factors contributing to geographic variations. METHODS: Surgical volumes for acetabular (K124-2) and pelvic (K125) fractures were categorized by age, gender, and prefecture in the National Database of Health Insurance Claims and Specific Health Checkups of Japan (2016-2022). Correlation analyses assessed relationships between surgical volumes, aging populations, and orthopedic surgeon availability. RESULTS: Surgical volumes of the elderly increased among individuals over 65, with a notable rise in female pelvic fractures. Acetabular fractures were more prevalent in younger males. Urban areas with more orthopedic surgeons showed higher surgical volumes (p < 0.0001), while aging population rates correlated negatively (p < 0.0001). CONCLUSION: ORIF for acetabular and pelvic fractures is increasing in Japan's aging population. Surgeon distribution influences surgical volumes, highlighting the need for treatment guidelines in primary care and telemedicine-based strategies. |
