Objective Objective to evaluate the clinical significance of lateral malleolar’s anatomical hook-plate in treating ankle fracture including distal fibular fracture. Methods Twenty-eight patients of ankle fracture including distal fibular fracture were treated from January 2006 to January 2009. There are 12 males and 7 females with an average age of 36 years (ranged from 18 to 72 years). The fractures were classified by Danis-Weber system. A type in 8 cases. B type in 11 cases. The average time of post injury was 6 days (ranged from 6 hours- 16 days).The distal fibular fracture were treated with lateral malleolar’s anatomical hook-plate. Medial malleolus was fixed with cancellous bone screw. The posterior malleolus was fixed with screw or plate according to the form of fracture.Results The mean follow-up period was 18.8 months with a range from 6 to 32 months. According to Mazur ankle joint scoring scale system, the final result was scored from 67 to 92 (average 86.3). excellent in 12 cases, good in 4 cases, fair in 2 cases. dissatisfactory in 1 cases. The total rate of good results was 84.2%. Conclusion The lateral malleolar’s anatomical hook-plate represents a definite biomechanical superiority in treating fracture of external malleolar, with advantage of restoring anatomic structure, joint activity effectively and firm fixation.
