To evaluate the middle-long-term clinical effects of unilateral and bilateral percutaneous kyphoplasty(PKP) for vertebral fragility fracture in the elderly. ⋯ Middle-long-term clinical effects of unilateral and bilateral percutaneous kyphoplasty for vertebral fragility fracture are safe and satisfactory, and may be extended as a minimally invasive method. Unilateral approach for PKP has advantages of short operation time, relative less trauma, thus is a more ideal method.

To observe different bone cement dispersion types of PVP, PKP and manipulative reduction PVP and their effects in the treatment of senile osteoporotic vertebral compression fractures and the bone cement leakage rate. ⋯ Bone cement dispersion type is different in PVP, PKP and manipulative reduction PVP operation. The bone cement dispersion of mass type and mixed type to recovery of compressed vertebral body is better than diffusion type, and there is no obvious difference in clinical effect in different bone cement dispersion type early and middle term.
