The occurrence of pain after total hip arthroplasty emphasizes the covert nature of acute stress fractures. In a 46-year-old woman, the lesion was not apparent on initial radiograms; cultures as well as gram stain of the joint fluid were also negative, and the initial ESR and white blood count were normal, effectively ruling out infection. An arthrogram, performed to demonstrate possible loosening, revealed stress fracture of the superior pubic ramus. Without evidence of active infection, it may therefore prove wise to postpone revision surgery for several weeks or until diagnosis of an occult fracture becomes radiologically apparent.
全髋关节置换术后疼痛的出现凸显了急性应力性骨折的隐匿性。在一名46岁女性中，最初的X线片上病变并不明显；关节液培养及革兰氏染色结果也均为阴性，且最初的血沉和白细胞计数正常，有效排除了感染。为了显示可能的松动而进行的关节造影显示耻骨上支应力性骨折。在没有活动性感染证据的情况下，因此推迟数周进行翻修手术或直到隐匿性骨折在影像学上变得明显后再手术可能是明智的。
