    Description of Event or Problem · 1

    THIS REPORT IS BEING FILED AFTER THE SUBSEQUENT REVIEW OF THE FOLLOWING LITERATURE ARTICLE, LI S.L., LU Y., WANG M.Y.(2015). IS CROSS-SCREW FIXATION SUPERIOR TO PLATE FOR RADIAL NECK FRACTURES? BONE JOINT J 2015;97-B:830-5. THIS STUDY COMPARES THE OUTCOMES OF TWO METHODS OF FIXATION OF DISPLACED FRACTURES OF THE RADIAL NECK. THE 58 PATIENTS WITH A MEAN AGE OF 38.5 YEARS (18 TO 56), WERE TREATED IN A NONRANDOMISED STUDY WITH SCREWS (N = 29) OR A PLATE AND SCREWS (N = 29) ACCORDING TO THE SURGEON'S PREFERENCE. THE PATIENTS WERE REVIEWED AT ONE YEAR. RADIOGRAPHS AND FUNCTIONAL EVALUATIONS WERE CARRIED OUT UP TO ONE YEAR POST-OPERATIVELY, USING THE BROBERG AND MORREY FUNCTIONAL EVALUATION SCORE, RANGE OF MOVEMENT, AND ASSESSMENT OF COMPLICATIONS. RESULTS: ALL FRACTURES HEALED WITHIN FOUR MONTHS OF SURGERY. THERE WERE NO WOUND INFECTIONS, NERVE INJURIES, LOSS OF REDUCTION, OR FAILURES OF FIXATION IN ANY PATIENTS. FOUR PATIENTS DEVELOPED HETEROTOPIC OSSIFICATION AT THREE TO FOUR MONTHS POSTOPERATIVELY, OF WHICH ONE (3.4%) WAS IN THE SCREW GROUP AND THREE (10.3%) WERE IN THE PLATE GROUP (FISHER'S EXACT TEST, P = 0.61). THIS IS REPORT #1 OF 2 FOR (B)(4). THIS REPORT IS FOR UNKNOWN HEADLESS CANNULATED SCREWS AND REFERS TO THE HETEROTOPIC OSSIFICATION AT THREE TO FOUR MONTHS POSTOPERATIVELY.
