    THIS REPORT IS BEING FILED AFTER THE REVIEW OF THE FOLLOWING JOURNAL ARTICLE: XIONG, J. ET AL (2018), TREATMENT OF UNSTABLE DISTAL CLAVICLE FRACTURES (NEER TYPE II): A COMPARISON OF THREE INTERNAL FIXATION METHODS, JOURNAL OF INTERNATIONAL MEDICAL RESEARCH, VOL. 46(11), PAGES 1-6 (CHINA). THE PURPOSE OF THIS RETROSPECTIVE STUDY IS TO COMPARE THE CLINICAL EFFICACY OF THREE INTERNAL FIXATION METHODS FOR DISTAL CLAVICLE FRACTURES (NEER TYPE II): CLAVICULAR HOOK PLATE (GROUP A), ANATOMICAL PLATE (GROUP B), AND ARTHROSCOPIC ENDOBUTTON (GROUP C). BETWEEN 2001 AND 2014, A TOTAL OF 58 PATIENTS (34 MALE AND 24 FEMALE) WERE INCLUDED IN THE STUDY. THESE PATIENTS WERE DIVIDED INTO 3 GROUPS BASED ON THE FIXATION METHOD: PATIENTS IN GROUP A (AO HOOK PLATE; SYNTHES SOLOTHURN, SWITZERLAND) CONSISTED OF 25 PATIENTS WITH A MEAN AGE OF 46.5±15.8 YEARS, THOSE IN GROUP B (AO DISTAL CLAVICLE ANATOMIC LOCKING PLATE; SYNTHES) CONSISTED OF 5 PATIENTS WITH A MEAN AGE OF 38.0±14.7 YEARS AND THOSE IN GROUP C (COMPETITOR¿S DEVICE) CONSISTED OF 28 PATIENTS WITH A MEAN AGE OF 41.9±13.5 YEARS. ALL PATIENTS WERE FOLLOWED-UP AND RADIOGRAPHS WERE TAKEN TO EVALUATE FRACTURE HEALING. THE AVERAGE FOLLOW-UP PERIOD WAS 57 MONTHS (RANGE, 7-160 MONTHS). THE FOLLOWING COMPLICATIONS WERE REPORTED AS FOLLOW UNDER GROUP A: 8 PATIENTS OF WHICH THE CORACOCLAVICULAR LIGAMENTS WITH SUTURES WHICH COMPLETELY RUPTURED WERE REPAIRED. 15 PATIENTS OF WHICH THE HOOK PLATES WERE REMOVED AT AN AVERAGE OF 18.8 MONTHS AFTER SURGERY. 1 PATIENT THE HOOK PLATE COULD NOT BE REMOVED BECAUSE OF TOTAL LOCKING BETWEEN THE SCREW AND PLATE. IN THIS PATIENT, SHOULDER DISCOMFORT PERSISTED UNTIL THE LAST FOLLOW-UP. UNKNOWN PATIENTS COMPLAINED OF FOREIGN BODY AND/OR IMPINGEMENT SENSATIONS FROM THE IMPLANTS; THESE SENSATIONS RESOLVED IN 14 PATIENTS AFTER REMOVAL OF THE HOOK PLATES. 2 PATIENTS DEVELOPED FRACTURES PROXIMAL TO THE IMPLANT AT 10 DAYS AND 4 WEEKS POSTOPERATIVELY, RESPECTIVELY. BOTH FRACTURES HEALED AFTER FIXATION WITH ANATOMIC AND RECONSTRUCTIVE PLATES. THE FOLLOWING COMPLICATIONS WERE REPORTED AS FOLLOW UNDER GROUP B: 5 PATIENTS WHICH THE CORACOCLAVICULAR LIGAMENTS WITH SUTURES WHICH COMPLETELY RUPTURED WERE REPAIRED. THIS REPORT CAPTURES THE REPORTED 1 PATIENT IN WHICH THE HOOK PLATE COULD NOT BE REMOVED BECAUSE OF THE TOTAL LOCKING BETWEEN THE SCREW AND PLATE. SHOULDER DISCOMFORT IN THIS PATIENT PERSISTED UNTIL THE LAST FOLLOW-UP. THIS REPORT IS FOR AN UNKNOWN SYNTHES SCREWS. THIS IS REPORT 4 OF 4 FOR (B)(4).
