带线锚钉与克氏针张力带治疗髌骨骨折对比研究

Case control study on suture anchors and Kirschner wires with tension band for the treatment of patellar fracture

目的比较带线锚钉与克氏针张力带治疗髌骨骨折的临床疗效。方法回顾性分析大同市第五人民医院骨科2009年1月至2012年3月采用带线锚钉及克氏针张力带治疗髌骨骨折62例，其中锚钉固定组34例，克氏针张力带组28例，观察比较两组的骨折愈合时间、膝关节屈曲角度、术后并发症及再次手术率。结果所有患者均获随访，两组骨折均愈合，骨折愈合时间比较差异未见统计学意义（P〉0．05）。膝关节屈曲角度锚钉固定组优于克氏针张力带组（P〈0．05）。术后并发症及二次手术率克氏针张力带组多于锚钉固定组，差异有统计学意义（P〈0．05）。结论带线锚钉治疗髌骨骨折膝关节功能恢复快，能够有效减少术后并发症。

Objective To compare the clinical efficiency of suture anchor and Kirschner wires with tension band on patellar fracture. Methods The clinical data of 62 patients with patella fracture from January 2009 to March 2012 were treated with suture anchors and Kirschner wires with tension band, with 34 cases in the suture anchors group and 28 cases in the Kirschner wires with tension band group. The knee joint range of motion, the bone healing time and the complications of the two groups from the surgery were compared. Results All patients were followed up. The fractures healed well. There was significant difference in terms of the knee joint range of motion and the com- plications from the surgery （ P 〈 0.05 ） , while no difference in the bone healing time （ P 〉 0.05 ）. Conclusions This suture anchors resulted in satisfactory outcomes for patella fractures without any obvious complications.
