摘要:

背景:Hoffa骨折属于关节内骨折,临床少见,临床及X射线片诊断较困难,容易漏诊,治疗困难,如治疗不当可出现骨折不愈合、膝关节功能障碍等并发症。
目的:观察空心拉力螺钉治疗 Hoffa骨折临床疗效。
方法:2007年5月至2012年4月采用空心拉力螺钉治疗Hoffa骨折患者7例,男5例,女2例;年龄23-57岁,平均37岁。均行膝关节正、侧位 X射线检查及 CT、MRI 检查。治疗后随访观察骨折愈合、并发症发生情况及患肢功能恢复情况。
结果与结论:所有患者均获得随访,随访18-36个月,平均24个月。骨折均获得愈合,无内固定松动及骨折再移位等并发症发生,患者膝关节活动范围均大于110°,按膝关节 Letenneur评分标准评定疗效,优6例、良1例,按照美国特种外科医院膝关节评分(HSS评分)均为优。结果可见采用空心拉力螺钉治疗Hoffa骨折,具有固定牢靠、并发症少、可早期进行功能锻炼、疗效好等优点。

Abstract:

BACKGROUND: Hoffa fracture belongs to intraarticular fracture, and is rare in the clinic. It is difficult to be diagnosed in clinic and radiographs. Missed diagnosis easily occurs, so it is hard to be cured. Improper therapy would induce disunion of fracture or knee dysfunction.
OBJECTIVE: To observe the clinical efficacy of Hoffa fracture treated with cannulated lag screws.
METHODS: From May 2007 to April 2012, seven patients with Hoffa fracture were treated with cannulated lag screws, including 5 males and 2 females, aged from 23 to 57 years old, averagely 37 years old. They accepted the X-ray, CT and MRI examinations of anteroposterior and lateral knee joints. After surgery, facture healing, the incidence of complications and recovery of limb function were observed during follow-up.
RESULTS AND CONCLUSION: All patients were followed up for 18-36 months, averagely 24 months. Fractures were healed. Complications did not occur such as loosing fixation and fracture re-displacement. The range of motion of knee joint was greater than 110°. According to the knee Letenneur assessment criteria, there were excellent in six cases and good in one case. According to the U.S. Hospital for Special Surgery knee score, the efficacy was excellent. Results suggested that cannulated lag screws for Hoffa fracture were characterized by stable fixation, few complications, early functional exercises and good efficacy.
