Abstract:

Objective　To investigate the clinical effect of treating volar marginal rim fractures with arthroscopy-assisted combined variable angle lcp volar rim distal radius plates.　Methods　From January 2016 to November 2016, 19 patients who suffered from extreme distal radial fractures were treated in Department of Orthopedics. The assessments included fracture healing time,function of wrist according to DASH scores and Mayo scoresplate.　Results　All of the 19 cases were followed up for 6~16 mouths,with average of 12.1 months．All fractures healed and no loss of reduction occurred in 9~13weeks，with anaverage of 11.2 weeks.The Mayo score was 86 to 95 points(average 92.8 points). the DASH score was from 6 to 11points(average 9.7 points).    Conclusions    Arthroscopy-assisted combined variable locking compression plate may be an effective way to treat extreme distal radial fractures with compound internal fixation on the basis of morphological feature of fractures and the situation of soft tissue because of  easiness of the fixation,early functional training and excellent wrist joint function, it is worth clinical promotion.
