Objective:
The objective of this study is to investigate the
effects of cement distribution index on refracture of adjacent
segments after percutaneous vertebroplasty.
Methods:
A retrospective analysis was adopted to
complete the research. 143 patients received percutaneous
vertebroplasty for osteoporotic vertebral compression
fracture from April 2011 to March 2014 were covered in
this study. All patients were followed up for 1 year. Cases
developed adjacent segment fracture (re-fracture group).
The other cases were not observed new fracture (control
group). After operations, X-rays were taken from all patients.
Index I to V was used to describe the position and shape
of cement in vertebrae, and volume-cubage index was
computed based on the cement volume and vertebral
cubage. Age, gender, bone mineral density, distribution
index, volume-cubage index, cement leakage was evaluated
in the 2 groups. Then the significant indictors were used to
be in variables in Logistic regression analysis.
Results:
134 cases were followed up for 1 year at last. 18
cases (13.4%) developed adjacent vertebral fractures. BMD
in re-fracture groups was lower than that of control group
(P<0.05). While the rates of cement leakage of re-fracture
group were higher than that of control group (P<0.05). There
was significant difference in distribution index between
refracture and control groups (P<0.05). While the differences
in age, gender, cement volume and volume-cubage index
were not significant between the 2 groups (P>0.05). Bone
mineral density, cement leakage and distribution index
affected on adjacent fractures by Logistic regression analysis.
Conclusion:
Low bone mineral density, cement leakage
and poor distribution of cement in vertebrae might be
the risk factor affecting adjacent vertebral fracture after
percutaneous vertebroplasty.
