Clinical research about the improved PVP method in treatment of acute osteoporotic vertebral compression fractures

The traditional percutaneous vertebroplasty (PVP) could induce massive radiation and side injuries to the tissues around the fractured centrum. This study was designed to reduce the radiation and damage and improve the treatment efficiency of PVP.

Forty four patients who diagnosed to be acute osteoporotic single vertebral compression fractures were collected and randomly divided into traditional group and improved group, and these two groups were separately treated by the traditional and improved PVP which assisted by the preoperative digital design. The treatment outcome between these two groups was compared and analyzed by Students' t test and χ² test.

Compared with the traditional PVP, the improved PVP could significantly reduce the X-ray fluoroscopy times for determining puncture point (14.41 ± 4.00 vs. 6.82 ± 2.15, p < 0.001) and puncture route (22.73 ± 3.89 vs. 13.36 ± 3.39, p < 0.001), the X-ray fluoroscopy times during the operation (76.59 ± 12.4 vs. 34.82 ± 6.74, p < 0.001), operation duration (28.64 ± 7.43 min vs. 15.23 ± 4.4 min, p < 0.001), and total radiological dose (588.85 ± 53.86 cGycm² vs. 276.5 ± 58.17 cGycm², p < 0.001). The improved PVP could also significantly decrease the visual analog score at intra-operation (7.68 ± 0.78 vs. 4.50 ± 0.67, p < 0.001) and 1 day after the operation (2.45 ± 0.51 vs. 2.16 ± 0.36, p < 0.05). Besides, the improved PVP could not significantly affect the Oswestry disability index after operation (p > 0.05).

The improved PVP operation could significantly reduce the total radiological dose and X-ray fluoroscopy times, protect the patients and medical staff, and reduce the pain caused by the operation.

This trial was registered in China clinical trial registration center and the registration number was ChiCTR-INR-17011557.
