Event or Problem Description
It was reported by legal initial left total hip arthroplasty on an unknown date with unknown components.An orif was performed for a distal femoral fracture.1st revision was three years post implantation for mechanical loosening of unknown products with zb components placed.Subsequently, two years from the first revision, a 2nd revision was performed due to limb length discrepancy with custom spacer device.During the procedure noted necrotic synovial tissue, could not decouple the body from the stem due to stripping of the thread, and thin femoral bones.The head and liner were exchanged, and all other implants remained in place.
Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional and/or corrected information.Proposed component code: mechanical (g04): stem.Medical records/radiographs were provided and reviewed by a health care professional.A review of the available records identified findings of the reported issues.During a hip revision, the surgeon removed the locking screw but could not decouple the arcos proximal body (11-301323) from the arcos stem (11-301622) because the threads in the proximal body stripped and the taper disengagement tool could not be/remain assembled to the proximal body.This revision surgery was aimed at implanting a custom arcos adapter and new standard line implants to address the leg length discrepancy of the patient.See attached email conversation.A definitive root cause cannot be determined.The event was confirmed via medical records.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
