Orthopedic surgery robotic navigation system assists in complex thoracolumbar compression fracture surgery

257 Views

Recently, Director Wang Boyao and his team at the Second Affiliated Hospital of Nanjing Medical University successfully completed a complex percutaneous vertebroplasty for thoracolumbar compression fracture with the assistance of the PAI Medical orthopedic surgery robotic navigation system. Feedback from Director Wang:

1. The use of the robot effectively shortened the operation time: this was a complex double vertebral fracture operation, which took at least twice as long to perform with bare hands, but with the assistance of the orthopedic surgery robotic navigation system, the operation was completed within one hour.

2. Robotic one-time puncture with high success rate: The orthopedic surgery robotic navigation system is the superior choice for this kind of complex surgery. Because this kind of complex surgery is time-consuming and labor-intensive with high risk, the orthopedic surgery robotic navigation system can complete the puncture at one time after positioning, which saves time and effort, while the accurate positioning improves the safety of the surgery.

3. Robot-assisted vertebroplasty is effective: for simple surgery, many doctors may feel that the robot is too big and unnecessary, but in fact, injecting bone cement with the assistance of the orthopedic surgery robotic navigation system, which has better diffusion effect, will bring better recovery.

Preoperative profile and examination

Patient’s age: 60 years old

Patient’s gender: female

Patient condition: trauma causing low back pain for 1 day

Preoperative examination: compression fracture of thoracic 12 and lumbar 4 vertebrae

▲ Preoperative images

Difficulties of this operation:

❖ The diseased vertebrae are far apart, with a total spacing of 5 vertebrae from T12-L4.

The patient had degenerative changes of the lumbar spine, scoliosis and rotation of the vertebrae, significant spinal deformity, and the angle of the pedicle completely deviated from the normal anatomical position.

Advantages of using the surgical robot for positioning:

Director Wang and his team studied the patient’s medical history and imaging findings several times and concluded that percutaneous vertebroplasty is difficult to perform unassisted, time-consuming and labor-intensive, with significant intraoperative patient discomfort and poor cooperation, and decided to perform percutaneous vertebroplasty with the assistance of the orthopedic surgery robot navigation system on the patient to shorten bedtime and reduce complications in order to better alleviate the patient’s pain.

Robot-assisted thoracolumbar compression fracture surgery

Based on the 3D images of the thoracic and lumbar spine lesions collected by the 3D C-arm of Puai Medical, path planning was performed on the interface of the orthopedic surgery robotic navigation system to automatically guide into the location and needle entry direction of the set lesions.

Robot planning image

The lesions that originally required repeated fluoroscopic comparison and positioning can be accurately targeted for entry at once through the intelligent algorithm of the orthopedic surgery robotic navigation system. After all the guide pins are implanted, the arch and vertebral body are placed along the direction of the guide pins, a channel is established, bone cement is injected along the channel to restore the height of the vertebral body, and its diffusion is observed, and the injection of bone cement is stopped after satisfactory results are achieved.

Intraoperative images

The operation was completed successfully with small incision and less bleeding, reducing the damage to the muscles of the low back and effectively reducing the postoperative pain level, traumatic stress and the incidence of chronic pain in the low back in the long term. the number of X-ray exposures was also significantly reduced, taking care of the health of doctors and patients.

Post-operative images

Low surgical trauma

Post-operative review screw implantation was accurate, vertebral body height recovered well, and sensory movement of lower limbs was good. The patient was able to turn over on his own under the guidance of medical care on the second day after surgery, and moved down to the ground earlier under the protection of the lumbar circumference, and the pain level was significantly reduced and the activity was significantly improved compared with that before surgery.
