[Assessment of percutaneous vertebroplasty and percutaneous kyphoplasty for treatment of senile osteoporotic vertebral compression fractures].
OBJECTIVE
To investigate the clinical effects and safety of vertebroplasty and kyphoplasty for the senile osteoporotic vertebral compression fractures.


METHODS
From December 2004 to June 2008, 28 patients (40 vertebrae) with osteoporotic vertebral compression fractures were treated with percutaneous vertebroplasty (PVP group), there were 11 males (14 vertebrae) and 17 females (26 vertebrae), with an average age of 72 years (ranged, 70 to 91 years). The fracture site of vertebral body was from T5 to L5. Other 31 patients (43 vertebrae) were treated with percutaneous kyphoplasty (PKP group), there were 13 males (18 vertebrae) and 18 females (25 vertebrae), with an average age of 74 years (ranged, 70 to 92 years). The fracture site of vertebral body was from T4 to L5. Theapeutic effects of all the patients were observed after operation, the item included visual analog scale (VAS), Oswestry score, Cobb angle, the height of anterior and middle column vertebra, and the incidence of cement leakage.


RESULTS
There was significant decrease in VAS score and Oswestry score after operation in both groups, there was significant difference between preoperative and postoperative (P < 0.01). There was no significant difference in VAS score and Oswestry score between two groups (P > 0.05). There was no significant difference in Cobb angles and the height of anterior and middle column vertebra between two groups before and after operation (P > 0.05). Among them, there were 3 vertebrae cement leakage in PVP group (7.5%) and 2 in PKP group (4.7%), but no clinical sympton occurred. There was no significant difference in the incidence of cement leakage between two groups (P > 0.05).


CONCLUSIONS
Vertebroplasty and kyphoplasty are safe and effective methods in treating senile osteoporotic vertebral compression fractures, which can restore the height of fractured vertebra, relieve pain and improve function as well as minimize the incidence of cement leakage.
