Revision Strategies in Spinal Deformity With Hardware Failure: A Biomechanical Study

Failure of the posterior rods in long thoracolumbar deformity correction cases often requires revision surgery to treat the pseudoarthrosis and prevent loss of correction. While the entire rod can be replaced, this involves opening the entire incision which can lead to increased morbidity. Other clinically advantageous options include minimally invasive surgical approaches such as percutaneous insertion of connectors and additional rods.
