双侧髋关节缺血性坏死

介绍
在两个髋关节的运动过程中，由于疼痛而导致的运动范围减小。

患者资料
年龄：20岁
性别：男

X射线

正位


正位

双侧股骨头重塑，部分塌陷，显示硬化和不规则区域。

案例讨论

其特征与两股骨骺长期缺血性坏死伴继发性退行性变一致。

髋关节缺血性坏死比其他部位更常见，可能是由于站立时血液供应不稳定和高负荷的综合作用。

临床表现

最常见的症状是髋关节、大腿、腹股沟和臀部疼痛。虽然很少有病人直到晚期才有症状。

病理

通常影响上关节面（10-2点钟之间），从髋关节最前面开始。

病因学

它可以被认为是创伤性的（继发于股骨颈骨折）或非创伤性的。在非创伤性病例中，40%为双侧。
