摘要
目的:观察应用镍钛聚髌器治疗髌骨骨不连的临床疗效。方法:回顾性分析2002-01/2008-12解放军第二军医大学附属长海医院骨科收治的髌骨骨不连患者8例,男5例,女3例;年龄18～65岁,平均41.5岁;髌骨骨折距本次手术时间5～28个月。均采用以镍钛聚髌器为主要内固定方式,适当结合自体髂骨植骨,术后早期进行功能锻炼。观察骨愈合时间、伤口愈合情况,膝关节恢复情况及并发症。结果:8例患者均获得随访,时间6个月至7.5年。术后3～12周,平均8.6周膝关节屈伸水平与健侧相仿,无骨块移位、植入物松动、断裂等并发症发生。按张春才疗效评定标准:优6例,良1例,可1例,优良率88%。结论:伴有膝关节功能障碍的髌骨骨不连,通过手术重建关节面的平整性,有效固定并早期进行术后功能锻炼是挽救膝关节功能的有效方法。
OBJECTIVE： To observe the clinical effect of Ni-Ti patella concentrator in the treatment of nonunion of patella. METHODS： The 8 patients with patellar nonunion that had been admitted to Department of Orthopedics, Changhai Hospital of Second Military Medical University form January 2002 to December 2008 were retrospectively analyzed, including 5 males and 3 females aged 41.5 years （range 18-65 years）. Duration between initial fracture and the treatment was 5 to 28 months. All patients were mainly given internal fixation with Ni-Ti patella concentrator combined with bone implantation with iliac crest. Postoperative early exercises were performed. Time of bone union, healing of wound and function of knee were observed. RESULTS： Eight patients were followed up with duration of 6 months to 7.5 years. The function of injured knee were healed nearly as good as the uninjured side at an average of 8.6 weeks （range 3 to 12 weeks）. No bone block displacement, loosening or breakage of internal fixation happened. According to Zhang＇s scores, the results were excellent in 6 cases, good in 1 and fair in 1. The excellent and good rate was 88% CONCLUSION： Operative reconstruction of smooth joint surface, rigid internal fixation and early functional exercise are effective remedies for refractory nonunion of patella combined with handicapped joint function.
