Abstract:
Pedicle screw instrumentation has become the standard stabilization of the posterior lumbar spine.Loosening due to osteoporosis is the common reason for failure.Bone cement augmentation is regarded as an efficient way to enhance screw strength in osteoporotic bones.In this review,a brief introduction to the recent advances in researches on the biomechanics of the bone-screw interface,the pedicle screw augmentation technique and the materials of bone cement is presented.The paper emphasizes the significance of studies on the augmentation indications,vicariousness activity in osteoporosis sclerotin and the strength.
