【摘要】 目的总结骨小梁金属重建棒植入治疗早期成人股骨头缺血性坏死(avascular necrosis of the femoral head, AVN)的手术方法及临床疗效。方法 2005年3月—2007年1月,采用骨小梁金属重建棒植入治疗28例AVN患者。男18例,女10例;年龄18～56岁,平均30.6岁。创伤性7例(所有内固定均已取出),激素性10例,酒精性5...
Key Points: € BME on MRI in AVN of femoral head indicates a subchondral fracture. € BME in AVN of the femoral head represents ARCO stage 3/4 disease. € CT identifies subchondral fractures and femoral head collapse better than MR imaging. € This knowledge helps to avoid understaging and...
【Key words】Osteonecrosis of the Femoral Head; Joint Preservation Surgery; AVN CAGE; Surgical Technique; Efficacy; Survival Rate 前言 股骨头坏死(osteonecrosis of the femoral head, ONFH)是致残率极高的进展性疾病。晚期ONFH可通过全髋...
Stage I: In this stage, X-ray is normal but in MRI, dead bone can be detected. Stage II: X-ray can reveal bone damage changes related to AVN. At this stage, the collapse of bone of femoral head has not taken place. Stage III: X-ray shows sign of bone collapse (crescent sign)....

中早期诊断股骨头无菌性坏死可使医生能尽可能保留关节而不是手术切除。所谓早期诊断,一是指前放射线期(preradiologic stage),即在普通X线片甚至CT扫描均无阳性性表现前诊断;二是指股骨头塌陷前得以诊断。前者在核磁共振(magnetic resonance imaging,MRI)应用前,非侵入法难以确诊,后者诊断较易。本文综述中早期诊断方法...
【Abstract 】Objective:To investigate the surgical technique,short-term clinical results and complications of a novel joint preserving procedure involving a 3D printed porous titanium cage (A VN CAGE)in treatment of early stage osteonecrosis of the femoral head (ONFH),to explore the optimal ...
MRIAvascular necrosis of the femoral head is one of the most common skeletal complicationsamong renal allograft recipients complaining of hip pain. While bilateral avascularnecrosis is more frequent than the unilateral type, we report a case of unilateralavascular necrosis of the hip occurring post ...
