Objective To discuss and analyze the clinical effect of double locking plate internal fixation combined with early activity of elbow under potent analgesia for treatment of distal humerus C type fractures. Methods 73 patients with distal humerus C type fractures in our hospital from January 2007 to December 2012 were selected, in which, 23 patients with double locking plate internal fixation combined with early activity of elbow under potent analgesia were set as the observation group, and other 50 patients with treatments of reconstruction of titanium plate/pipe type titanium plate internal fixation were set as the control group. All patients were followed-up for 5~16 months, and the recovery of elbow function and pain scores after surgery of two groups were compared. Results The excellent and good rate of recovery of elbow function after surgery of observation group was 91.3%, significantly higher than 66.0%of control group (P<0.05). There was no significant difference between two groups in pain scores before surgery (P >0.05), but after surgery, the pain score of observation group was (1.81±0.39), significantly lower than (4.08±0.84) of control group (P<0.05). Conclusions Double locking plate internal fixation combined with early activity of elbow under potent analgesia for the treatment of distal humerus C type fractures is good for postoperative analgesia and recovery of elbow function, so it has good clinical effect.%目的：探讨双锁定钢板内固定联合强效镇痛下早期活动肘关节治疗肱骨远端C型骨折的方法与临床效果。方法选取我院自2007年1月至2012年12月收治的23例肱骨远端C型骨折患者作为观察组，采用双锁定钢板内固定联合强效镇痛下早期活动肘关节治疗方法。另取对照组50例，采用重建钛板/管型钛板内固定治疗。术后随访5~16个月，比较两组患者的术后肘关节功能恢复和疼痛评分情况。结果观察组术后肘关节功能恢复优良率为91.3%，对照组为66.0%，观察组明显高于对照组，差异具有统计学意义(P<0.05)；两组患者术前疼痛评分比较无显著差异(P>0.05)，术后观察组(1.81±0.39)明显低于对照组(4.08±0.84)，差异具有统计学意义(P<0.05)。结论双锁定钢板内固定联合强效镇痛下早期活动肘关节治疗肱骨远端C型骨折有利于术后镇痛和肘关节功能的恢复，具有较好的临床效果。
