Abstract
Polymethylmethacrylate can significantly enhance the stability of different injectable pedicle screws in osteoporotic lumbar vertebrae, and screw stability is significantly correlated with the distribution pattern and the injected volume of PMMA. The closer the PMMA to the pedicle and the greater the quantity of injected PMMA, the greater is the pedicle screw stability. Injection of 2.0âmL of PMMA through screws with four lateral 180° holes or of 1.0âmL of PMMA through screws with six lateral 180° holes increases the stability of pedicle screws.
