Objective To study the efficacy of complex distal humeral fractures in adults with the parallel-plate technique. Methods 16 patients with complex distal humeral fractures were treated by open reduction and internal fixation using parallel plating. The function of elbow was assessed according to Mayo elbow performance score (MEPS) and plain X-ray films. Results 16 patients had been followed up for 3~18 months (mean, 9.5 months). The mean fracture healing time was 6~16 weeks (mean, 10.5 weeks), with no nonunion, delayed union, displacement, avascular necrosis of implant failure. The range of motion of the elbow joint averaged 113.2°and the mean MEPS was 83.9. The overall excellent to good rate was 87.5%. Conclusion The parallel-plate technique can obtain stable internal fixation, early postoperative rehabilitation and satisfactory clinical effect in the treatment of complex distal humeral fractures in adults.%目的 观察平板双钢板内固定治疗成人肱骨远端复杂骨折的临床效果.方法 采用平板双钢板内固定方法治疗16例成人肱骨远端复杂骨折患者,按照Mayo肘关节功能评分(MEPS)标准及X线平片结果评估疗效.结果 本组16例患者骨折均一期愈合,时间为6～16周,平均10.5周,无一例内固定松动及骨折移位发生.术后均随访3～18个月,平均10个月,患侧肘关节MEPS评分为46～100分(平均83.9分),疗效评定:优8例(50％),良6例(37.5％),可2例(12.5％),差0例,优良率为87.5％.结论 平板双钢板内固定治疗成人肱骨远端复杂骨折,固定强度和抗疲劳作用强,利于肘关节早期功能锻炼,效果满意.
