髌骨爪与克氏针张力带治疗髌骨骨折效果的比较

Comparison of patella concentrator and Kirschner wire in the treatment of patellar fracture

目的比较克氏针张力带和髌骨爪治疗髌骨骨折(PF)患者的效果。方法 89例PF患者,实施克氏针张力带治疗的44例纳入对照组,实施髌骨爪治疗的45例纳入观察组,比较两组的治疗效果。结果观察组的手术时间和骨折愈合时间均短于对照组(P<0.01或0.05)。两组的治疗效果差异无统计学意义(Hc=0.501,P>0.05),但观察组膝关节功能障碍、内固定失败并发症的发生率低于对照组(P<0.05),关节功能的恢复情况优于对照组(Hc=7.123,P<0.01)。结论对PF患者而言,髌骨爪固定的稳定性更佳,在保障治疗效果的同时可缩短手术时间和骨折愈合时间,降低术后并发症的发生率,促进患者术后关节功能的恢复。

Objective To compare the clinical efficacy of patella concentrator and Kirschner wire in the treatment of patellar fracture(PF). Methods A total of 89 PF patients were selected and divided into two groups. The Control Group(n=44) was treated with Kirschner wire while the Observation Group(n=45) was treated with patella concentrator. The therapeutic effect of two groups was compared. Results The operation time and fracture healing time of the Observation Group were shorter than those of the Control Group(P<0.01 or 0.05). There was no significant difference in the therapeutic effect between the two groups(Hc=0.501, P>0.05). The incidence of knee dysfunction and the complications of internal fixation failure in the Observation Group was lower than that in the Control Group(P<0.05), and the recovery of joint function in the Observation Group was better than that in the Control Group(Hc=7.123, P<0.01). Conclusion The patella concentrator has better stability for PF patients, which can shorten the operation time and healing time, reduce the incidence of postoperative complications and promote the joint function recovery while ensuring the therapeutic effect.
