【摘要】 目的探讨不等距无头加压螺纹钉治疗Hoffa骨折的效果。方法 2010年6月~2012年12月,我院共收治Hoffa骨折5例,其中外髁骨折3例,内髁骨折1例,双髁骨折1例。患者均为男性;年龄17~54岁,平均年龄35.8岁。5例行前正中切口切开复位,不等距无头加压螺纹钉内固定治疗,术后第2d拔管,开始主动和被动活动锻炼,术后2个月逐渐下地负重行走。结果 5例均获随访,随访时间4~30个月,平均15个月。骨折均获骨性愈合,功能恢复参照Letenneur方法进行评估,优良4例,可1例。本组无深部感染、内固定松动和关节僵直发生。结论临床上Hoffa骨折比较少见,股骨外髁发生率高于股骨内髁,双髁骨折更少见。不等距无头加压螺纹钉把持力强,无头结构适合股骨髁部骨折,可以达到骨折端解剖复位、坚强稳定的内固定及早期功能锻炼,术后临床效果良好。更多还原

【Abstract】 Objective To investigate the effect of headless compression screw in treating Hoffa’s fracture.Methods Five patients with Hoffa’s fracture were treated form Jun. 2010 to Dec. 2012,including 3 cases of external condyle fractures,1 case of medial condyle fractures and 1 case of bicondylar fracture. All patients aged from 17 to54 years with an average of 35. 8 years old. All cases received open reduction via a median incision and underwent fixation with headless compression screws. Patients were extubated at 2 days after operation and then began active and passive exercise. Weight-bearing walking began at 2 months after operation. Results All patients were followed up for 4-30 months with an average of 15 months. All fractures got bone union. Knee joint function was rated based on Letenneur evaluation system and showed excellent and good in 4 cases,fair in 1 case. There was no deep infection,implant failure or joint stiffness. Conclusion Hoffa’s fracture is rare. Headless compression screw has enough strength,which can achieve anatomical reduction,rigid internal fixation and early knee joint functional exercise. Headless compression screw fixation is a good treatment method for fracture of femoral condyle.更多还原
