This is a retrospective cohort study of type C distal humeral fractures (AO classification system) aimed at evaluating the effectiveness of current operative treatment options.
Thirty-seven patients with type C distal humeral fractures, treated operatively from January 2002 to September 2016, were retrospectively studied. Thirty-two were eligible for inclusion. Patients were treated by open reduction using the posterior approach, olecranon osteotomy and parallel-plate two-column internal fixation. Patients were evaluated for fracture healing, functional outcomes and complications (infection, ulnar neuropathy, heterotopic ossification and need for implant removal). Restoration of the normal anatomy was defined by measuring carrying angle, posterior angulation and intercondylar distance of distal humerus.
The mean follow-up time was 8.7 years [range 2-15.5 years, standard deviation (SD) = 3.96]. Mean time to fracture union was 8 weeks for 29 patients (90.6%) (range, 6-10 weeks). In nine cases, there was malunion of varied importance (28.1%). There was one case with postoperative ulnar neuropathy and one case with deep infection. The mean Disabilities of the Arm, Shoulder and Hand (DASH) score and mean Mayo Elbow Performance Score (MEPS) were 20 (range 0-49) and 83.3 (range 25-100), respectively.
In complex distal humerus fractures, the posterior approach with olecranon osteotomy and parallel plating of two columns, after anatomic reconstruction of the articular segment, is a prerequisite for successful elbow function.

这是一项针对C型肱骨远端骨折（AO分类系统）的回顾性队列研究，旨在评估当前手术治疗方案的有效性。
回顾性研究了2002年1月至2016年9月期间接受手术治疗的37例C型肱骨远端骨折患者。其中32例符合纳入标准。患者采用后入路切开复位、尺骨鹰嘴截骨及双钢板双柱内固定治疗。对患者进行骨折愈合、功能结果及并发症（感染、尺神经损伤、异位骨化及内固定取出需求）评估。通过测量肱骨远端的提携角、后倾角及髁间距离来定义正常解剖结构的恢复情况。
平均随访时间为8.7年[范围2 - 15.5年，标准差（SD）= 3.96]。29例患者（90.6%）骨折愈合的平均时间为8周（范围6 - 10周）。9例存在不同程度的畸形愈合（28.1%）。有1例术后发生尺神经损伤，1例发生深部感染。手臂、肩部和手部功能障碍（DASH）评分及梅奥肘关节功能评分（MEPS）的平均值分别为20（范围0 - 49）和83.3（范围25 - 100）。
在复杂的肱骨远端骨折中，采用后入路、尺骨鹰嘴截骨及双柱平行钢板固定，并对关节面进行解剖重建，是肘关节功能成功恢复的前提条件。
