Establishing Minimal Important Change After Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures

Key Points

• The aim is to determine the minimal important change in back pain and disability after vertebroplasty in patients with osteoporotic vertebral compression fractures (OVCF).
• Measured VAS back pain and ODI scores pre- and post-intervention
• Compared changes in scores with EQ-5D metrics
• Examined patient outcomes in the context of improvement thresholds
• VAS back pain and ODI effectively distinguished between improved and unchanged patients compared to EQ-5D
• Patients required larger changes in pain and disability scores to signify improvement than those in other spinal surgery groups.
