    Description of Event or Problem · 1

    THIS REPORT IS BEING FILED AFTER THE SUBSEQUENT REVIEW OF THE FOLLOWING JOURNAL ARTICLE: SCHLIEMANN, B. ET AL. (2012). COMPLEX FRACTURES OF THE PROXIMAL HUMERUS IN THE ELDERLY-OUTCOME AND COMPLICATIONS AFTER LOCKING PLATE FIXATION. MUSCULOSKELET SURG SUPPL 1, 96, S3-S11. THE AUTHORS CONDUCTED A RETROSPECTIVE STUDY TO EVALUATE FUNCTIONAL AND RADIOLOGICAL OUTCOMES AND PATIENT SATISFACTION AFTER LOCKING PLATE FIXATION OF THREE AND FOUR PART PROXIMAL HUMERUS FRACTURES WITH SYNTHES DEVICE, PROXIMAL HUMERAL INTERNAL LOCKING SYSTEM (PHILOS) PLATE. BETWEEN JANUARY 2004 AND DECEMBER 2008, 48 PATIENTS OLDER THAN 65 YEARS WERE TREATED; AVERAGE FOLLOW-UP WAS 44 MONTHS. OF 48 PATIENTS, 27 WERE SUBSEQUENTLY AVAILABLE FOR FOLLOW-UP. MEAN PATIENT AGE WAS 71 YEARS (RANGE: 65-85 YEARS); SEVEN PATIENTS WERE MEN AND 20 PATIENTS WERE WOMEN. PERCENTAGE INCIDENCES OF COMPLICATIONS WERE AS FOLLOWS: SCREW PERFORATION (22.2) ASSOCIATED WITH LOSS OF REDUCTION (44.4), IMPINGEMENT (18.5), IMPLANT FAILURE (3.7), AVASCULAR NECROSIS (29.6) AND PSEUDARTHROSIS (3.7). REVISIONS WERE REPORTED FOR SCREW PERFORATION (TWO), IMPINGEMENT (THREE), IMPLANT FAILURE (ONE), AVASCULAR NECROSIS (ONE) AND PSEUDARTHROSIS (ONE). THE AUTHORS NOTED THAT COMPLICATIONS MAY HAVE OCCURRED IN THE SAME PATIENT. THE AUTHORS CONCLUDED THAT, DESPITE A HIGH COMPLICATION RATE, THE RESULTS OF THE LOCKING PLATE FIXATION OF COMPLEX DISPLACED PROXIMAL HUMERUS FRACTURES IN THE ELDERLY ARE SATISFYING AND COMPARABLE TO THOSE OF PRIMARY ARTHROPLASTY AND MINIMALLY INVASIVE TREATMENTS. THIS IS A REPORTABLE MALFUNCTION REPORT INDICATING PERCENTAGE INCIDENCES OF COMPLICATIONS: SCREW PERFORATION (22.2). THE AUTHORS NOTED THAT COMPLICATIONS MAY HAVE OCCURRED IN THE SAME PATIENT. THIS REPORT IS FOR AN UNKNOWN PHILOS SCREW. THIS REPORT IS 2 OF 5 FOR COMPLAINT (B)(4).
