目的：目的：评价髌骨横形骨折固定的临床效果，采用平行空心螺钉固定张力前8字形钢丝。设计：前瞻性，临床。患者：10例髌骨横形骨折移位患者采用标准化康复方案，早期采用持续被动膝关节运动。结果：临床和影像学愈合时间、特殊外科医院膝关节评分以及与文献队列研究的比较。术后平均8周出现临床愈合，平均13周出现影像学愈合。尽管大多数患者是老年人且骨质疏松，但早期在受限区域内持续被动活动并不影响骨折复位的质量。主观和功能的结果，使用医院的特殊外科膝关节评分与以前发表的报告，70%达到优秀或良好outcome.Conclusions：所描述的髌骨骨折的固定技术的临床结果相当于髌骨骨折固定与修改张力带钢丝的报告。优点包括低切迹结构，对局部软组织结构造成的植入物刺激程度较低，与早期限制活动的使用兼容，并提供了一种方法来挽救3例传统张力带钢丝未能保持骨质疏松骨解剖复位的病例。
Objective: To evaluate the clinical results of transverse patella fracture fixation with a tensioned anterior figure-eight wire placed through parallel cannulated screws.Design: Prospective, clinical.Patients: Ten patients with displaced transverse patella fractures were managed with a standardized rehabilitation protocol that employed early continuous passive knee motion.Outcome Measures: Time to clinical and radiographic union, Hospital for Special Surgery Knee Scores, and comparisons with literature cohort studies.Results: Clinical union occurred at an of average eight weeks and radiographic union at a mean of thirteen weeks postoperatively. Early continuous passive motion over a restricted are did not compromise the quality of fracture reduction, even though the majority of patients were elderly and had osteopenic bone. Subjective and functional results using Hospital for Special Surgery Knee Scores were comparable to previously published reports, with 70 percent achieving an excellent or good outcome.Conclusions: The described fixation technique for transverse patella fractures had clinical results equivalent to reports of patella fractures fixed with modified tension band wiring. Advantages included a low-profile construct that caused lesser degrees of implant irritation to local soft tissue structures, was compatible with the use of early restricted motion, and afforded a method to salvage three cases in which traditional tension band wiring failed to maintain an anatomic reduction in oteoporotic bone.
