【目的】探讨采用解剖型锁定钢板（ALCP）治疗尺骨鹰嘴 Mayo Ⅱ型骨折患者的临床疗效。【方法】回顾性分析本院骨科2013年1月至2015年1月收治的尺骨鹰嘴 Mayo Ⅱ型骨折患者113例，其中64例患者采用切开复位 ALCP 内固定治疗（ALCP 组），49例患者采用克氏针张力带进行治疗（克氏针组），比较两组围术期指标和预后。【结果】ALCP 组和克氏针组患者的手术时间、出血量、功能锻炼时间、骨折愈合时间比较差异均无统计学意义（P ＞0．05）；术后2个月、6个月，ALCP 组的术后疼痛、运动功能、肘关节稳定性、日常活动评分均显著高于克氏针组患者，其差异均具有统计学意义（P ＜0．05）；术后6个月，ALCP 组肘关节功能优良率90．63％显著高于克氏针组的75．51％（P ＜0．05）。【结论】ALCP 治疗尺骨鹰嘴 Mayo Ⅱ型骨折患者较克氏针固定术后肘关节功能恢复更好，疗效满意，值得临床推广应用。“,”Objective]To investigate the clinical effect of anatomic locking plate (ALCP) in treatment of olecranon Mayo Ⅱ fractures .[Methods]A retrospective analysis of 113 cases of patients with olecranon MayoⅡ fractures in the Department of orthopedics of our hospital from January 2013 to January 2015 was conduc‐ted .Among them ,64 patients were treated by open reduction and internal fixation with ALCP (ALCP group) ,49 patients were treated with Kirschner wire tension band (Kirschner group) ,Perioperative indicators and prognosis were compared between the two groups .[Results]There was no significant difference in the op‐eration time ,amount of bleeding ,functional exercise time and fracture healing time between the ALCP group and the Kirschner group ( P > 0 .05) ;2 months and 6 months after surgery ,the postoperative pain ,motor function ,elbow stability and daily activity score of the ALCP group were significantly higher than those in the Kirschner group ,the difference was statistically significant ( P < 0 .05) ;At 6th month after operation ,the ex‐cellent and good rate of elbow joint function in the ALCP group was 90 .63% ,which was significantly higher than that in the Kirschner group 75 .51% ( P < 0 .05) .[Conclusion]Compared with Kirschner fixation ,the AL‐CP treatment of olecranon Mayo Ⅱ fractures has a better postoperative elbow function recovery with satisfied efficacy .It is worthy of clinical application .
