title: Treating Eyres type IV and V coracoid fracture using the acromion osteotomy approach.
abstract: OBJECTIVE
  To introduce a surgical method of treating Eyres type IV and V coracoid fracture using the acromion osteotomy approach and to further analyse the clinical effectiveness of this surgical procedure.
  
  
  METHODS
  Nine patients were included in this study with a mean follow-up time of 23.3 months (range, 14.0-34.0 months). Patients were evaluated with use of the Constant score, the Simple Shoulder Test (SST) score and a visual analogue scale (VAS) pain score. Moreover, the shoulder range of motion was also observed.
  
  
  RESULTS
  The mean operation time was 91.6 min with a blood loss volume ranging from 310 to 530 ml. The fractures of eight patients had recovered between 10 and 12 weeks post operation with no signs of infection, screw loosening, plate breaking or other internal fixation failures, while one case had non-union at 34 months' follow-up. The mean Constant score increased from 75.6 points preoperatively to 91.0 points at follow-up. The mean VAS score decreased from 5.3 preoperatively to 1.0 at follow-up, while the average SST score increased from 7.1 points preoperatively to 10.0 points at follow-up. The mean abduction, forward flexion, external rotation, internal rotation and backward extension angles were 162°, 159° 50°, 55° and 47°. Five cases were classified as excellent, three cases were marked as good and one case was classified as fair.
  
  
  CONCLUSIONS
  Treating coracoid fracture through the approach of acromion osteotomy could be an effective treatment option with minimise damages.
