Anterior dislocation of the native hip joint is an uncommon presentation accounting for around 15% of all hip dislocations. It is usually the result of a high-energy impact in circumstances such as a motor vehicle accident or a fall from a significant height. A delay in relocation of more than 6 h has been associated with a high risk of avascular necrosis of the femoral head. We report the case of a 75-year-old man who suffered an anterior dislocation of his native hip following a fall from a standing height, associated with an acute cerebrovascular stroke. There was significant delay in the recognition of the dislocation due to the coexistent signs of the stroke. This case illustrates that hip dislocation can occur following a low-energy mechanism of injury with the possibility of serious long-term consequences if it is not promptly recognised and treated.
原发性髋关节前脱位是一种不常见的表现，约占所有髋关节脱位的15%。它通常是在诸如机动车事故或从高处坠落等情况下受到高能量撞击的结果。复位延迟超过6小时与股骨头缺血性坏死的高风险相关。我们报告一例75岁男性病例，该患者从站立高度跌倒后发生原发性髋关节前脱位，并伴有急性脑血管中风。由于中风的并存症状，脱位的识别存在显著延迟。该病例表明，低能量损伤机制也可导致髋关节脱位，如果不能及时识别和治疗，可能会产生严重的长期后果。
