Stabilisation of a pelvic discontinuity with a posterior column plate with or without an associated acetabular cage sometimes results in persistent micromotion across the discontinuity with late fatigue failure and component loosening.

We believe that these chronic discontinuities are really chronic fracture non-unions incapable of healing.
