- The study investigates the biomechanical impact of varying paraspinal muscle mass on cervical spine stability after Anterior Cervical Discectomy and Fusion (ACDF).
- Three models were created to simulate different postoperative states of the multifidus muscle: muscle training (120% quality), muscle atrophy (80% quality), and control (100% quality).
- Results showed that muscle atrophy increased adjacent segment disc pressure, implant stress, capsular ligament stress, and range of motion (ROM), raising risks of degeneration and implant failure.
- Conversely, the muscle training model demonstrated superior biomechanical stability compared to the control model.
- The study concludes that paraspinal muscle quality significantly affects postoperative stability, advocating for preoperative muscle evaluation and postoperative strength training to improve surgical outcomes.
