目的探讨空心螺钉钢丝张力带治疗髌骨骨折的临床效果. 方法 2006年1月至2007年4月,运用空心螺钉钢丝张力带技术治疗髌骨骨折36例.根据AO分型:A型6例,C型30例.其中女23例,男13例,年龄45～86岁,平均58岁.所有患者均为闭合性损伤,直接暴力12例,间接暴力24例.切开复位后屈曲膝关节,二根1mm导针经髌骨上极或下极平行钻入,然后选择4.0mm半螺纹自攻空心螺钉沿导针拧入,最后经空心钉以"8"字的方式穿入钢丝并拧紧完成张力带结构. 结果 36例患者均获平均8个月的随访,平均愈合时间6周.所有患者无伤口感染、内固定松动、软组织激惹等并发症.采用Bostman髌骨骨折疗效评分标准于术后6周进行功能评定:优32例,良4例,优良率100%. 结论空心拉力螺钉结合钢丝张力带技术治疗髌骨骨折固定可靠,软组织激惹和复位丢失率低,是一种值得推荐的治疗手段.

Objective To investigate the clinical effects of stabilizing patellar fractures with can-nulated lag screws and tension band wires. Methods From January 2006 to April 2007, 36 cases of patellar fractures were treated with cannulated lag screws and tension band wires. They were 23 females and 13males, and their ages ranged from 45 to 86 (average, 58) years old. Fractures were caused by direct force in 12 cases and by indirect force in 24 cases. After open reduction, the knees were placed in flexion, the fractures were first fixed with 2 parallel K-wires from the proximal pole or distal pole, and then four-millimeter cannulated lag screws followed K-wires across the fracture site. A wire was then threaded through the cannulated screws to create a figure-of-eight pattern tension band across the anterior surface of the patella. Results All the 36 cases were followed up for a mean of 8 months. All fractures healed without complications, such as in-cision infection, loosening of fixation, or irritation to soft tissue. Restoration of the knee joint motion was exeellent in 32 cases and good in 4 cases according to Bostman score system after 6 weeks postopera-tively. Conclusions Because stabilization of patellar fractures with tension band wires and cannulated lag screws can acquire reliable fixation, low rate of irritation and reduction loss, it is a recommendable method.
