摘要:

背景:切开复位克氏针张力带内固定是修复髌骨横行骨折的传统方法,但存在克氏针滑脱、钢丝断裂等并发症。Cable-Pin系统是一种新型内固定装置,作者利用微创方式将其应用于髌骨横行骨折,取得了良好的修复效果。
目的:对比观察Cable-Pin系统微创技术与切开复位克氏针张力带内固定修复髌骨横行骨折的效果及并发症发生情况。
方法:纳入80例影像学确诊为髌骨横行移位的患者,随机分为两组,微创组40例接受Cable-Pin系统微创内固定治疗,40例接受切开复位克氏针内固定治疗。随访时间点分别为治疗后1,3,6,12和24个月,随访内容包括疼痛目测类比疼痛评分、膝关节活动度以及Bostman膝关节功能评分。
结果与结论:微创组疼痛缓解情况在治疗后1,3个月要优于对照组(P < 0.05),此种优势在治疗后6个月即消失。治疗后3-24个月,微创组膝关节屈曲训练更快,屈曲角度更大,显著优于对照组(P < 0.05)。此外微创组患者内固定不适引起并发症发生率要低于传统组(P < 0.05)。提示患者接受Cable-Pin系统微创内固定后疼痛缓解更明显,患膝活动度更大,膝关节功能恢复更好,并发症发生率降低,其修复效果优于传统克氏针内固定治疗。

Abstract:

BACKGROUND: Open reduction and Kirschner wire tension band technique has been a traditional surgical method for the treatment of patella fracture. However, there still exist some complications such as Kirschner wire slippage and breakage. Cable-Pin system is a new fixation device. A series of good clinical results has been achieved in patients with patella fracture using this fixation device through a minimally invasive way.
OBJECTIVE: To compare and investigate the clinical results of minimally invasive fixation with Cable-Pin system and Kirschner wire tension band technique for patella fracture and the complications.
METHODS: Eighty patients with radiology-confirmed transverse displacement of patella participated in this trial, and were randomly divided into two groups. Forty patients underwent a minimally invasive technique and the others had conventional open surgery using Kirschner wire. At postoperative intervals of 1, 3, 6, 12, and 24 months, pain was measured by Visual Analogue Scale scores, range of motion was measured by goniometry, and knee function was evaluated using the Bostman clinical grading scale.
RESULTS AND CONCLUSION: Easement of pain was better in the minimally invasive surgery group than in the control group at 1 and 3 months after treatment (P < 0.05). Above dominance disappeared at 6 months after treatment. At 3-24 months, the knee flexion training was faster and flexion angle was greater in the minimally invasive surgery group, and results were significantly better than in the control group (P < 0.05). The incidence of discomfort fixation-induced complications was lower in the minimally invasive surgery group than in the conventional open surgery group (P < 0.05). These data confirm that after minimally invasive fixation with Cable-Pin system, pain was noticeably lessened, range of motion of affected knee was great, the recovery of knee function was better, the incidence of complications was reduced, and the repair effect was better than the conventional Kirschner wire fixation.
