Properties of PMMA Bone Cement Modified with Nano-hydroxyapatite and Acetone

ARCHive-SR, 2019
Fracture in the adjacent levels is one of the consequences to the use of commercial poly methylmethacrylate (PMMA) bone cement. Modified PMMA with a reduced Young’s modulus was found to be safer for cancellous bone augmentation procedures.
