Abstract
Background
Osteoporotic compression fractures (OVCFs) commonly occur in aged people, and as much
as one-third of these fractures progress to chronic pain. Kyphoplasty (KP) is proved
to be efficacious for pain relief and vertebral height restoration in chronic OVCFs,
but there is still no data available about the clinical and radiographical outcomes
compared by unipedicular and bipedicular KP in treating chronic painful OVCFs.
Purpose
To assess the clinical and radiographical outcomes in treating chronic painful OVCFs
compared by unipedicular and bipedicular KP.
Methods
Fifty-eight patients with a total of sixty-six chronic painful OVCFs were enroled
in our study. They were randomly allocated into two groups: group I (n = 33) was treated with unipedicular KP and group II (n = 25) with bipedicular KP. The operation times for each group were recorded and compared.
Preoperative and postoperative of visual analogue scores (VAS) and oswestry disability
index (ODI) scores were compared 2 weeks after surgery within each group and between
groups. The radiographic outcomes were evaluated by the restoration rate (RR) in the
most compressed point of the vertebral bodies.
Results
Significant improvement on the VAS, ODI scores and RR was noted in each group (p < 0.001), and there is no significant difference existing in clinical outcomes between
the two groups. The mean operation time for each vertebra in group I was significantly
shorter than in group II (p < 0.001). But the RR in group II was higher than in group I (p = 0.041).
Conclusion
Both unipedicular kyphoplasty and bipedicular kyphoplasty can achieve satisfactory
clinical and radiographic outcomes in treating the chronic painful OVCFs and the operation
time is shorter in unipedicular kyphoplasty. However, the bipedicular kyphoplasty
is more efficacious in height restoration.
