Abstract：Objective To evaluate the effectiveness of the arthroscopy-assisted reduction and internal fixa-tion by hollow screw for treatment of the ankle with posterior malleolus fracture .Methods The clinical data of 16 patients[11 males and 5 females ranged from 19-65 (average,26) years] with posterior malleolus fracture from Jan. 2009 to Dec.2012 was retrospectively analyzed .According to Lauge-Hansen classification ,there were 3 supinationev-ersion stageⅢfractures,10 supination-eversion stage Ⅳfractures,and 3 pronation-eversion stage Ⅳfractures.Ac-cording to AO/OTA classification,there were 4 case of 43-B2,10 cases of 43-B3,and 2 cases of 43-C3.All the pa-tients were treated with arthroscopy-assisted reduction and internal fixation by hollow screw .The clinical effects were evaluated according to AOFAS scores and VAS scores .Results All the patients were followed up from 12 to 32 months(average 19 months).The bone healing was obtained from 10 to 16 weeks (average 12.8 weeks).At the final review,the AOFAS score was from 83 to 100(average 93.4),the VAS score was from 0 to 3(average1.2).No trau-matic arthritis was observed . Conclusion Arthroscopy-assisted reduction and internal fixation by hollow screw for the treatment of acute ankle fractures is not only helpful for anatomical reduction of the articular surface ,but also can improve the clinical results with effective diagnosis and treatment of combined intra-articular disorders .
