Event or Problem Description
It was reported that patient's right hip was revised due to shell migration.On explantation of the shell and two screws, a minimal amount of bone ongrowth was observed on the shell.Surgeon's original intention was to revise only the shell and liner to competitor devices.Intra-operatively, surgeon decided to change patient's version as the competitor shell left the patient's limb length suboptimal with the existing stryker stem and head.A stryker shell with 2 screws, liner, head, and stem were revised to a competitor shell and liner with a stryker head and stem.Rep provided a pre-revision x-ray and reported that additional x-rays, medical records, and further information would not be released by the hospital or surgeon.
