目的:观察采用髌骨针治疗老年人髌骨粉碎性骨折的疗效及安全性。方法:选取山西省煤炭中心医院2016年5月至2018年5月收治的老年髌骨粉碎性骨折患者124例为研究对象，根据治疗方法的不同分为两组，各62例。对照组采用克氏针张力带钢丝固定术，观察组采用髌骨针联合钢丝内固定术。观察并比较两组手术情况、临床疗效、并发症及膝关节功能。结果:观察组手术时间[(55.5±12.5)min]明显短于对照组[(62.4±13.8)min]，差异有统计学意义(n t＝2.918，n P0.05)；观察组与对照组显效(51例比41例)、有效(10例比17例)比较差异有统计学意义(n Z＝2.107，n P<0.05)；观察组患者膝关节功能评分为(159.5±12.4)分，对照组膝关节评分为(135.1±14.0)分，观察组明显优于对照组，差异有统计学意义(n t＝10.273，n P<0.05)。观察组与对照组并发症发生率(4.84%比16.13%)比较，差异有统计学意义(χn 2＝4.211，n P<0.05)。n 结论:采用髌骨针治疗老年人髌骨粉碎性骨折疗效显著，可明显改善膝关节功能，且并发症少。“,”Objective:To explore the effect and safety of patella pin in the treatment of comminuted fracture of patella.Methods:From May 2016 to May 2018, 124 elderly patients with comminuted patellar fracture in Coal Central Hospital of Shanxi Province were selected.They were divided into two groups according to different treatment methods, with 62 cases in each group.In the control group, Kirschner wire tension band fixation was used, and in the observation group, patella pin combined with wire internal fixation was used.The operation condition, clinical effect, complications and knee joint function between the two groups were observed and compared.Results:The operation time of the observation group [(55.5±12.5)min] was significantly shorter than that of the control group [(62.4±13.8)min], the difference was statistically significant (n t=2.918, n P0.05). The therapeutic effect of the observation group was significantly better than that of the control group (n Z=2.107, n P<0.05). The score of knee joint function in the observation group was (159.5±12.4)points, which in the control group was (135.1±14.0)points, the difference was statistically significant (n t=10.273, n P<0.05). The incidence of complications in the observation group (4.84%) was significantly lower than that in the control group (16.13%) (χn 2=4.211, n P<0.05).n Conclusion:Patella pin has good effect on comminuted fracture of patella in the elderly, it can significantly improve the function of knee joint, and has less complications.
