Abstract：Objective To investigate the differences in the clinical effects between an open limited contact compression plate ( AOLCP) and external fixation combined with kirschner wire for distal radius intra-articular frac-ture.Methods The clinical data of 135 cases of distal radius intra-articular fracture in our hospital from Jan.2012 to Jun.2013 was analyzed.The cases were divided into AOLCP group(72 cases) and kirschner wire group(63 ca-ses) .The fracture healing, the range of motion in wrist joints and the difference in functional evaluation of distal radius fracture after treatment between two groups were compared.Results There was no significant difference in the average healing time between AOLCP group(6.2 ±1.3 weeks) and kirschner wire group(6.6 ±1.2 weeks;t=1.848,P=0.062).They were all healed and excluded with delayed healing and malunion.In the 6th and 12th months after treatment,the range of motion in wrist joints in two groups was measured.The results showed that the palmar flexion range of motion,dorsiflexion,pronation,supination,radial deviation,ulnar deviation in AOLCP group were significantly different from those in kirschner wire group and the mobility range of wrist joints of AOLCP group was superior to kirschner wire group(P<0.05).In the 12th month after treatment,the Dienst score of wrist joints function in AOLCP group was significantly higher than that in the kirschner wire group(P<0.05).The excellent rate in AOLCP group was 84.72%, significantly higher than that in kirschner wire group ( 69.84%, P<0.05 ) . Conclusion The treatment for distal radius fracture by AOLCP can get better long-term effects and is beneficial to the function recovery of wrist joints.
