Research Article: Efficacy analysis of robot-assisted percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fractures

Date Published: 2026-06-22

Abstract:
This study retrospectively evaluates the effectiveness of robot-assisted percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCF). Between October 2022 and October 2023, a total of 92 hospitalized OVCF patients at Shaanxi Provincial People's Hospital were divided into two groups: the traditional group ( n =?45, PKP) and the robot-assisted group ( n =?47, robot-assisted PKP). Both groups were followed up for one year after surgery. The study compared surgical outcomes, VAS scores, vertebral body height, Cobb angle, ODI scores, and the rate of cement leakage between the two groups. Compared to the traditional group, the robot-assisted group had fewer fluoroscopy frequency (11.25?±?2.27 vs. 14.58?±?3.63), fewer puncture needle adjustments (2.03?±?0.25 vs. 5.51?±?1.14), and a shorter operative time (36.53?±?3.74?min vs. 42.25?±?2.59?min, P <?0.05). However, the robot-assisted group needed longer preparation time (40.16?±?2.57?min) than the traditional group (8.18?±?1.03?min) ( P <?0.05). VAS scores in both groups were reduced at 1 day, 3 months, 6 months and 12 months compared to preoperative levels. At 6 months postoperatively, both groups had higher vertebral body midline height and lower Cobb angle ( P <?0.05). However, we found no significant differences between the two groups ( P >?0.05). Notably, the incidence of cement leakage was significantly lower in the robot-assisted group ( P <?0.05). Robot-assisted PKP can reduce fluoroscopy exposure and bone cement leakage, and have a shorter surgery time.
