目的 探讨直切口细克氏针加改良张力带治疗髌骨粉碎性骨折的疗效。方法 采用直切口细克氏针加改良张力带治疗65例髌骨粉碎性骨折患者。术后观察骨折愈合时间、X线片关节面平整程度、膝关节功能恢复情况。结果 骨折愈合时间平均为85.5 d，X线片示关节面平整度良好，术后关节功能优良率93.8 %。结论 该术式手术适应证较广、创伤小、固定牢固、疗效确切，是治疗髌骨粉碎性骨折的有效方法。

Objective To study the curative effect on comminuted patella fracture using vertical incision by internal fixation of fine Kirchner wires plus improved tensile band with steel wires. Methods 65 cases of comminuted patella fracture using vertical incision were treated by internal fixation of fine kirchner wires plus modified tensile band with steel wires, followed by the observation of postoperative time of fracture union, smoothness digree of joint surface on X-rays and restoration of knee joint function. Results The average time of fracture union was 85.5 days, and smoothness digree of joint surface on X-rays was fine. The excellent rate of joint function accounted for 93.8%. Conclusions It is an effective method in the treatment of comminuted patella fracture because of its wide indications, minimal invasion, firm fixation and satisfactory results.
