MEDICAL RECORDS PERTAINING TO THE IMPLANTATION WERE PROVIDED AND REVIEWED BY A HEALTHCARE PROFESSIONAL AND IDENTIFIED NO INTRAOPERATIVE COMPLICATIONS. MICROBIOLOGICAL TESTS REVEALED NO GROWTH. MEDICAL RECORDS PERTAINING TO THE REVISION SURGERY WERE PROVIDED AND REVEALED BY A HEALTHCARE PROFESSIONAL, IDENTIFYING THAT EARLY IMAGING SHOWED SLIGHT ACETABULAR CHANGES, WHILE A CONSULTATION REPORTED SEVERE RIGHT HIP AND LEG PAIN BUT NO RADIOGRAPHIC LOOSENING, LIKELY DUE TO A LUMBAR LIGAMENT INJURY. AN UNDATED THERAPY DISCHARGE NOTE INDICATED GOOD RECOVERY AND FULL WEIGHT-BEARING. AFTER THIS, CHROMIUM AND COBALT LEVELS WERE MARKEDLY ELEVATED, WHICH PERSISTED THE NEXT YEAR DESPITE X-RAYS SHOWING NO OSTEOLYSIS OR LOOSENING.

PATHOLOGY LATER, CONFIRMED CHRONIC SYNOVITIS WITH SIGNIFICANT METAL ABRASION, WITHOUT INFECTION OR MALIGNANCY. POSTOPERATIVE IMAGING SHOWED STABLE POSITIONING, THOUGH COBALT LEVELS REMAINED HIGHLY ELEVATED (116.3 G/L) IN (B)(6) 2015, WITH CHROMIUM AT 66.2 G/L. FINALLY, FOLLOW-UP TESTING DEMONSTRATED NORMALIZATION OF METAL ION LEVELS. BASED ON THE AVAILABLE INFORMATION, THE REPORTED EVENT CAN BE CONFIRMED.
