目的：研究双钢板治疗肱骨远端C 型骨折的疗效，并探讨影响预后的相关因素。方法：选取2009 年1 月至2013 年8 月86 例我院收治的肱骨远端C 型骨折患者，按知情同意原则随机分为双钢板固定组（43 例）及Y型钢板固定组（43 例），2 组患者均给予经尺骨鹰嘴截骨入路切开复位内固定术后再分别行双钢板及Y型钢板固定，记录两组患者的改良cassebaum 肘关节评分、骨折愈合时间及并发症情况，并分析影响患者预后的相关因素。结果：双钢板固定组治疗的优良率高于Y 型钢板固定组（P<0.05），骨折愈合时间及并发症发生率均低于Y型钢板固定组，差异均有统计学意义（P<0.05）；骨折类型、合并损伤、内固定方法、术后功能锻炼是影响预后的因素（P<0.05）。结论：双钢板的经尺骨鹰嘴截骨入路切开复位内固定术在治疗肱骨远端C型骨折患者时有良好的疗效，合并伤、内固定方法、骨折类型、术后锻炼是影响预后的因素，应针对性地采取措施。

英文摘要:

Objective:To study the efficacy of dual plate in treating the C-type distal humerus fracture and to explore the influencing factors of the prognosis.Methods:86 cases of C-type distal humerus fracture patients who were treated in our hospital from January 2009 to August 2013 were collected and devided into dual plate group (43 cases) and type-Y plate group (43 cases) randomly according to the principle of informed consent. Open reduction and internal fixation of olecranonosteotomy were given to both groups, the dual plate and Y plate immobilization were given to corresponding group, improved cassebaum elbow score, incidence of complications and fracture healing time of both groups were recorded, and the influencing factors of prognosis were analysed.Results:The rate of excellent and good of dual plate group was higher than that of the type-Y plate group, the fracture healing time and incidence of complications of dual plate group were lower than those of the type-Y plate group and the differences were all statistically significant (P<0.05); The fracture type, combined injury, internal fixation methods and function exercises were the factors affecting the prognosis.Conclusion:Open reduction and internal fixation of olecranonosteotomy of dual plate presents effectiveness in treating C-type distal humerus fracture, and the fracture type, combined injury, internal fixation methods and function exercises are the factors affecting the prognosis, according to which measures should be taken appropriately.
