Abstract:

BACKGROUND: Some scholars used three-dimensional printing technology to design and manufacture percutaneous guide templates to assist pedicle puncture, which reduces the times of fluoroscopy and operation time and increases the safety in percutaneous vertebroplasty (kyphosis). However, such guide templates are all “surface-contact guide templates”, and the guide templates need to be completely adhere to the skin during application. The change of the patient’s body position often causes the guide templates and the skin to not completely fit, and needs to be adjusted so many times or even loses the purpose of guiding. There were few studies on three-dimensional printing point-contact guide templates for percutaneous pedicle positioning.

OBJECTIVE: To explore the clinical effect of three-dimensional printing point-contact guide template in the treatment of thoracolumbar osteoporotic vertebral compression fractures with percutaneous vertebroplasty.
METHODS: Forty patients with single-segment osteoporotic vertebral compression fractures in Affiliated Huai’an Hospital of Xuzhou Medical University from January 2017 to April 2018 were enrolled, and were randomly divided into control and trial groups (n=20 per group). The control group underwent traditional percutaneous vertebroplasty, and the trial group received percutaneous vertebroplasty with the aid of three-dimensional printing point-contact guide templates. The times of fluoroscopy and the time before the surgical needle reached the ideal puncture position, the total times of intraoperative fluoroscopy, the operation time, and the Visual Analog Scale scores at baseline and 1 day postoperatively were recorded.
RESULTS AND CONCLUSION: Both groups of patients successfully completed the operation. The times of fluoroscopy and the time before the surgical needle reached the ideal puncture position, the total times of intraoperative fluoroscopy, and the operation time in the trial group were significantly lower than those in the control group (P < 0.05). The postoperative Visual Analog Scale scores in both groups were significantly lower than those at baseline (P < 0.05). These results indicate that the three-dimensional printing point-contact guide templates assisting the thoracolumbar osteoporotic vertebral compression fracture with percutaneous vertebroplasty, can facilitate the accurate placement of the needle, reduce the times of fluoroscopy and shorten the operation time.
