Percutaneous vertebroplasty has been known to rapidly relieve pain, permit early ambulation, and enhance the quality of life of patients and for osteoporotic vertebral compression fractures treatment. In this retrospective study, vertebral cancellous bone infiltration anaesthesia was feasible in considerably relieving patient pain than traditional local anaesthesia alone. The occurrence of intraoperative or postoperative issues did not increase, and effective clinical results following surgery obtained.

This study assessed the pain-relieving effectiveness of vertebral cancellous bone infiltration anaesthesia throughout the use of percutaneous vertebroplasty (PVP) procedure.

Total 112 patients were divided into 2 groups: Intervention group with 59 patients treated with vertebral cancellous bone infiltration anaesthesia and; control group with 53 patients with local anaesthesia alone.

A comparison of VAS, visual analogue scale score prior the surgery, during the establishment of the puncture channel, through pressure variations in the vertebral body, during bone cement injection, instantly after the surgery, and at 2 h and 1-day post-surgery was made between the groups. Patient’s satisfaction with the operation was noted and evaluated between groups.

No change in the VAS score amongst the groups prior to the surgery or during set up of the intraoperative puncture channel was found. During pressure variations in the vertebral body and bone cement injection, the intervention group had significantly lower VAS score as compared to the control group. Pain in the intervention group also significantly lowered as compared to control group instantly after the surgery and at 2 hours post-surgery, nonetheless, there was no noteworthy difference amongst the groups at 24 hours after the surgery (Table 1).

The patient satisfaction rate was 88% and 67% in the intervention group and the control group, respectively.

Vertebral infiltration anaesthesia of the cancellous bone may efficiently ease intraoperative pain. It may also improve the surgical experience of patient exclusive of hampering its clinical efficacy.
