Conditions

Osteoporotic Fracture

Keywords

Percutaneous kyphoplasty（PKP）, nerve block, posterior branch of spinal nerve

Brief summary

The purpose of this study was to block the posterior branch of lumbar spinal nerve during PKP operation and compare it with the patients without spinal nerve block, so as to verify the effect of posterior branch block of spinal nerve in relieving short-term and long-term residual low back pain after operation.

Detailed description

Patients older than 60 years old who underwent Percutaneous kyphosis(PKP) surgery for osteoporotic fractures were randomly divided into two groups. The lumbar spinal nerve branch was blocked with betamethasone and ropivacaine in the experimental group during PKP operation, while the lumbar spinal nerve branch block was not performed in the control group during PKP operation. The low back pain was evaluated at 1 week, 2 weeks, 1 month, 3 months and 6 months after operation using Visual analogue pain score(VAS)scale.So as to compare the effect of lumbar spinal nerve block on residual pain after PKP.

Design outcomes

Primary

Measure	Time frame	Description
Residual low back pain after operation	6 months after operation	Residual low back pain after operation using Visual analogue pain score(VAS) scale, VAS scores range from 0 to 10, more higher score means more severe pain, and residual back pain was defined as a VAS score greater than or equal to 4.
