【摘要】 目的:观测股骨头静脉回流障碍与骨髓水肿、关节积液量和临床症状的关系,探讨静脉回流障碍在股骨头坏死(ONFH)中的临床意义。方法:分析经病理证实的20例25髋成人ONFH患者的临床资料,全部患者行股骨头骨髓造影和1.5T MR配对检查。结果:25髋ONFH骨髓造影显示16髋股骨头静脉回流障碍,MRI显示17髋有骨髓水肿征象,两者经Kappa检验出现率明显一致(P<0.01);15髋有关节积液征象,股骨头静脉回流障碍与髋关节积液的发生率有密切相关(Spearman=0.949);13例出现临床症状,显示股骨头静脉回流障碍患者的临床症状出现率明显高于静脉回流正常患者(P<0.05)。结论:临床有症状患者均有股骨头静脉回流障碍、骨髓水肿及髋关节积液,股骨头静脉回流障碍可能是引起骨髓水肿及髋关节积液的主要原因,骨髓造影对观察股骨头坏死病情演变具有重要的临床意义。更多还原

【Abstract】 Objective:To evaluate the correlation of venous return disturbance(VRD),bone marrow edema(BME) and the amount of joint fluid with clinical symptoms in osteonecrosis of the femoral head(ONFH).Methods: Twenty patients (25 hips) with ONFH proved by pathology were parallelly examined by 1.5 T MR and medullograph.Results: In total 25 hips VRD was observed in 16 hips with medullograph and 13 hips with the clinical symptoms (P<0.05). BME was found in 17 with MRI (P<0.01),and the was found in 15 hips with MRI (Spearman=0.949). VRD were found in 16 hydrarthrus. Conclusions: ONFH patients with clinical symptoms have VRD,BME and the hydrarthrus. The medullograph is of value in monitoring the development of ONFH.更多还原
