Screw instrumentation

An understanding of fundamental biomechanical principles of the spine and fixation strategies is essential to avoid unnecessary subsequent failures.

Several implant devices are used for this purpose. The use of pedicle screws in spinal stabilization has gradually and dramatically increased 1) 2).

With improved fixation techniques, surgeons have attempted to limit the use of extra autogenous bone graft to avoid making a separate incision over the iliac crest. Allograft and synthetic bone have been used with pedicle-screw-based constructs, with greater or lesser success depending on the pathology and the host-related variables 3) 4).
