双半圆克氏针钢丝张力带内固定治疗髌骨骨折的临床研究

Treatment of patellar fracture by internal fixation using double semicircle Kirschner wire

目的:介绍自行设计的双半圆克氏针钢丝张力带内固定治疗髌骨骨折,评价其疗效。方法:48例髌骨骨折按Rockwood分型,Ⅱ型14例,Ⅴ型34例。男38例,女10例。年龄13～69岁,平均32岁。开放性骨折22例,闭合性骨折26例。全部采用双半圆克氏针钢丝张力带内固定方法治疗。结果:48例均随访5～37个月,平均8个月,疗效评定根据Bostman评分标准,优47例,良1例。结论:该张力带内固定符合生物力学原理,采用这种新的克氏针钢丝张力带内固定治疗髌骨骨折,疗效好、并发症少,值得推广应用。

Objective：To introduce evaluate a new tension band fixation for the treatment of pateUar fracture. Methods：Among 48 patients ,38 patients were male and 10 patients were female, with an average age of 32 years ranging from 13 to 69 years. According to Rockwood classification, 14 patients were Type Ⅱ fracture and 34 patients were Type Ⅴ fracture. Open fracture occurred in 22 patients and close fracture in 26 patients. All the patients with patellar fracture were treated with intermal fixation by use of double semicircle Kirschner wire. Results：All the patients were followed up from 5 to 37 months ,with an average of 8 months. According to Bostman evaluation standard, 47 patients obtained exeellet results and 1 good. Conclusion：The new tension band fixation meets to biomeehanies principle with minimal complication and can achieve good therapeutic effects for treating patellar fracture. The therapeutic method is worthy of applying.
