Recently, with the assistance of the new "Holosight intelligent visualization system" robot, the team of Lin Haodong, director of the Trauma clinical medical center of Shanghai General Hospital, and Wang Jiandong, chief physician, successfully treated a complex pelvic fracture and a femoral neck fracture using closed reduction and minimally invasive fixation techniques. To be noted, this is the first appearance of Holosight robot in Shanghai.

Mr. Xu, 68, was sent to Shanghai General Hospital for emergency treatment after falling from a height.

Upon comprehensive examinations, Mr. Xu was diagnosed as type C2 pelvis fracture, which was displaced and extremely unstable. He also suffered from type II diabetes, hypertension, coronary heart disease and other basic diseases. Since there are many vessels, nerves and important organs around the pelvis, the traditional open operation is extraordinarily difficult and dangerous.

After multidisciplinary consultation to stabilize vital signs and comprehensive communication with the patient, the trauma clinical medicine center team chose to implement the minimally invasive surgery (closed reduction and cannulated screw internal fixation of pelvic fracture)" for Mr. Xu with the assistance of the new "Holosight intelligent visualization system" robot.

Reportedly, traditional minimally invasive surgery for pelvic fractures requires surgeons to perform the operation with limited vision. Proficiency on regional anatomy, extensive surgical experiences, and repeated fluoroscopy are needed to complete the operation. Regional vessels and nerves are highly vulnerable due to the complex anatomy of the hip and pelvis. Moreover, both patients and surgeons would be exposed to a large dose of fluoroscopy radiation.

The "holosight intelligent visualization system" robot can realize the intelligent and accurate matching of bone model and spatial tracking data and complete real-time 3D modeling through intelligent feature recognition and automatic registration algorithm with the support of optical positioning technology. 3D model of fracture could be directly observed on the screen, which greatly simplified the whole procedure, including fracture reduction, intelligent planning and minimally invasive fixation.

During surgery, the trauma center team placed a locator at the iliac crest and installed R-type and L-type trackers. The holosight robot can track the patient's bones with high accuracy and display the real-time spatial structure without a giant incision to expose the fracture .

The fracture morphology of the patient is presented on the screen in the form of 3D animation model, enabling the surgeons to observe in real time from multiple views and any perspective. The minimally invasive internal fixation was completed with only a few 1-cm small incisions, which effectively fixed the fracture and avoided the risks of massive hemorrhage, vascular and nerve injury, etc.

In addition, the trauma center team also precisely implanted a femoral neck system (FNS) for the treatment of a patient with femoral neck fracture under the holosight robot navigation, and completed the minimally invasive operation with only a 3-cm incision.

According to reports, holosight trauma robot can provide accurate and visual treatment solutions for closed reduction and internal fixation of a variety of fractures.

The trauma center of Shanghai General Hospital practiced the concept of "accelerated rehabilitation surgery (ERAS)" and provided patients with efficient and high-quality diagnosis and treatment services through minimally invasive surgery, embedded postoperative rehabilitation and other measures.
