title: [Effectiveness of open reduction and internal fixation for Bosworth fracture].
abstract: OBJECTIVE
  To explore the operative methods and effectiveness of open reduction and internal fixation for Bosworth fracture.
  
  
  METHODS
  Between January 2005 and January 2012, 6 patients with Bosworth fractures caused by sprain were treated. There were 4 males and 2 females with an average age of 45.8 years (range, 24-73 years). The time from injury to operation was 1-5 days (mean, 1.8 days). They were all closed fractures. According to Lauge-Hansen classification, 6 cases were classified as supination-external rotation type. The surgical treatments included open reduction and internal fixation by plate and screws.
  
  
  RESULTS
  Infection occurred in 1 case and was cured after dressing changing; primary healing of incision was obtained in the other 5 cases. Six patients were followed up 15 months on average (range, 12-24 months). The X-ray films showed fracture healing in all cases, with an average healing time of 9.5 weeks (range, 8-13 weeks). No loosening or breaking of internal fixator was observed during follow-up. The average full load-walking time was 12 weeks (range, 10-17 weeks). According to the ankle and hindfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS), the average score was 89.5 (range, 81-94).
  
  
  CONCLUSIONS
  For Bosworth fractures, good results can be achieved by early diagnosis, open reduction and internal fixation.
