儿童髌骨下极撕脱骨折7例诊治分析

Diagnosis and treatment of 7 cases of lacerated fractures of the inferior patella in children

目的分析儿童髌骨下极撕脱骨折的诊治。方法1989年以来共有7例髌骨下极撕脱骨折儿童行手术治疗,年龄8～15岁,伤后就诊时间1h～6d。3例采用克氏针钢丝张力带固定,4例用可吸收线“8”字缝合,按膝关节疗效标准进行疗效评价。结果术后摄片复查骨折完全愈合,随访1～4年,疗效均达到优。结论在缺乏磁共振(MR)检查时,根据病史、症状、体征及髌骨位置测量a-b/b、d值、c线位置综合分析,经手术检查证实,可以确诊髌骨下极撕脱骨折。tmentof7casesoflaceratedfracrtmentofOrthopaedics,PeoplesHoObjectiveToanalyzethediagnoTotally7childrenwithlacerateagesrangedfrom8to15yearsold,wireandtensionbelt,and4sutureeffectswasdoneaccordingtotherom1to4years.Theradiogramsallpatientswereexcellent.

Objective To analyze the diagnosis and treatment of lacerated fractures of the inferior patella in children. Methods Totally 7 children with lacerated fractures of the inferior patella have been treated by surgery since 1989. Their ages ranged from 8 to 15 years old, and symptom duration from 1 hour to 6 days. 3 of them were fixed by Kirschner wire and tension belt, and 4 sutured with absorbable suture line in the shape of “8”. The evaluation of treatment effects was done according to the relevant knee joint scoring system. Results Postoperative follow ups ranged from 1 to 4 years. The radiograms after operation showed that the fractures united completely. The joint functions of all patients were excellent. Conclusion In the absence of MR (magnetic resonance), the lacerated fractures of the inferior patella can be diagnosed by analyzing the case history, symptoms, physical signs and the results of patella position measurements, before definite confirmation by surgical check-up.
