Event Description

It was reported that an initial left total shoulder arthroplasty was performed approximately 3 years ago.Subsequently, the patient reported to her surgeon that she had been doing fine until she reached down to grab something and felt a pain in her left shoulder.Follow up radiology confirmed fracture of the central screw with subsequent loosening and osteolysis from debris generation.The patient reports she has since had pain, difficulty with activities of daily living, and limited range of motion.The patient was revised to a reverse total shoulder approximately a year and a half ago due to glenoid implant fracture.During the revision, evidence of metallosis and wear were found as well as cystic defects and significant scar tissue.All components were removed and replaced with unknown product except for specifying implantation of a biomet base plate.No further information is available at this time and the study is now complete.
