O-arm Navigation-Assisted Minimally Invasive Spine Surgery

With the advancement of modern minimally invasive spine surgery techniques—particularly the integration of 3D computer-assisted navigation, image fusion, and intraoperative guidance—surgical precision has significantly improved. These technologies help minimize the risk of neural and musculoskeletal injury, as well as reduce the incidence of postoperative complications.

1. Preoperative Planning and Intraoperative Image-Guided Navigation：These tools enable surgeons to execute procedures with greater precision.

2. Reduction of Intraoperative Risks and Complications：The use of navigation technologies effectively decreases the likelihood of neural injury, intraoperative bleeding, and operative time.

3. Minimized Soft Tissue Disruption：Minimally invasive techniques help preserve soft tissue integrity, leading to reduced postoperative pain.

4. Faster Postoperative Recovery：Accurate screw placement and optimal positioning of spinal fusion implants contribute to effective symptom relief and facilitate a quicker recovery for patients.
