The reported devices are used for treatment.Review of the primary operative surgical notes for procedure performed on (b)(6) 2011 determined that excellent positioning and stability of the construct was confirmed.No complications were indicated.Review of the revision operative surgical notes for procedure performed on (b)(6) 2011 determined that the acetabulum was stable.The removal of ceramic femoral head verified this was without scoring, and no evidence of cobalt/chromium toxicity, eburnation, metal filings or hyper proliferative response of the joint was noted.A likely cause for the reported issue as noted by the surgeon in the postoperative notes is that the external rotators were detached and the patient appeared to have an anterior impingement as the source of his anterior hip pain.
