Implication

Narrative review evaluates fixation techniques and screw designs in osteoporotic vertebrae, highlighting strategies to enhance implant pullout strength.

Key Points

To provide an overview of current and proposed pedicle screw designs and surgical techniques aimed at enhancing pullout strength in osteoporotic bone.
Reviewed mechanical considerations and clinical trade-offs of pedicle screw fixation methods in compromised bone quality.
Evaluated axial pullout strength assessments across modifications including thread design alterations, pilot hole optimization, altered trajectories, and bone cement augmentation.
Optimizing screw thread design and pilot hole dimensions for non-self-tapping screws improves bone-implant interface purchase in low-density bone.
Modifying implant trajectories and applying bone cement augmentation notably enhance mechanical resistance to axial pullout forces.
