Abstract:
Objective To evaluate the precise percutaneous sacroplasty (PSP) assisted by a Renaissance robot for sacral insufficiency fractures (SIF).Methods The clinical data of 12 SIF patients were retrospectively analyzed who had been treated from March 2016 to March 2018 at Department of Spinal Surgery,Honghui Hospital.They were 5 males and 7 females,aged from 55 to 76 years (average,67.5 years).They all received PSP assisted by a Renaissance robot.Their operation time,hospital stay and intraoperative radiation were recorded.The clinical efficacy was evaluated by comparing their visual analogue scale (VAS) and Oswestry disability index (ODI) before surgery,1 day,3 and 12 months after surgery.Results All the 12 patients underwent surgery successfully with no complications like cement leakage.Their operation time ranged from 32 to 47 minutes (mean,36.8 minutes),their hospital stay from 12 to 25 hours (mean 17.5 hours) and their intraoperative exposure to radiation from 0.87 to 1.53 mSv (mean,1.27 mSv).All the patients were followed up for 12 to 18 months (mean,15.8 months).Their VAS (1.7 ± 0.7) and ODI (22.8 ± 4.1) one day after surgery were significantly decreased than the preoperative values (7.6 ±0.9 and 43.7 ±4.6) (P ＜ 0.05).At 3 and 12 months after surgery,their VAS scores were 2.0 ± 0.8 and 2.4 ±0.8 and their ODI scores 21.5 ±4.3 and 23.0 ±4.6,respectively,showing no significant differences from the values at 1 day after surgery (P ＞ 0.05).Conclusion The PSP assisted by a Renaissance robot is safe and leads to satisfactory clinical efficacy for SIF as bone cement can be accurately injected into the target area of the fracture.
