Shoulder traction device for enhanced conventional fluoroscopy during cervical spine operations

Area of Science:

• Orthopedics
• Neurosurgery
• Medical Imaging

Background:

• Biplanar fluoroscopic imaging is standard in cervical spinal surgery.
• Shoulder superimposition frequently obstructs clear visualization of the cervical spine during these procedures.

Purpose of the Study:

• To design and evaluate an intraoperative traction device to overcome limitations in cervical spine fluoroscopy.
• To improve the quality of intraoperative fluoroscopic images during cervical spinal surgery.

Main Methods:

• Development of a novel intraoperative traction device with a traction band for applying force during fluoroscopy.
• Preoperative fitting of the device to patients for intraoperative use.
• Comparison of fluoroscopic image quality with and without the traction device.

Main Results:

• The intraoperative traction device effectively prevented shoulder superimposition on cervical fluoroscopic images.
• Fluoroscopic images obtained using the device were demonstrably superior to those without it.
• The device was found to be safe and easy to use by surgical operators.

Conclusions:

• The developed intraoperative traction device significantly enhances the quality of cervical spine fluoroscopic imaging.
• This device is particularly beneficial for improving visualization of the lower cervical spine in challenging surgical cases.
• The device offers a practical and effective solution for a common imaging challenge in cervical spinal surgery.
