The device, used in treatment, was not returned for evaluation but the images were reviewed, and the heterotopic ossification was confirmed.The clinical/medical investigation concluded that, based on the limited information provided, the clinical root cause of the first revision (b)(4) could not be concluded.The 2nd revision was reportedly due to pain and heterotopic ossification, which is supported by the x-ray image (b)(4).The patient impact beyond the reported pain, ossification and two revisions, could not be determined.No further medical assessment could be rendered at this time.Should clinically relevant documentation/information become available, the clinical/medical task may be re-evaluated.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Factors and/or some potential probable causes that could contribute to the reported event have been identified as overuse or excessive pressure on the joint, injury, and/or patient condition.Based on this investigation, the need for corrective action is not indicated.Without the return of the actual product involved, our investigation could not proceed.Should the device or additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
