Osteolysis is a significant long-term problem in hip arthroplasty. Plain radiographs are the routine investigation of choice for monitoring hip arthroplasty patients; however, the recognition of clinically significant osteolysis can be challenging. We present two case reports of arthroplasty patients with ballooning and expansion of the superior pubic ramus with loss of the normal concavity of the ilio-pectineal line. Both patients subsequently displayed massive pubic osteolysis at the time of revision surgery. We suggest that the presence of convexity of the ilio-pectineal line/superior pubic ramus indicates established pelvic osteolysis.
骨溶解是髋关节置换术的一个重大长期问题。平片是髋关节置换术后监测的常规首选检查方法;然而,识别临床上显著的骨溶解可能具有挑战性。我们报告了两例髋关节置换患者的病例,这些患者的耻骨上支出现球囊样扩张和膨胀,导致耻骨联合线的正常凹陷消失。这两例患者在翻修手术时都出现了大量耻骨骨溶解。我们认为,耻骨联合线/耻骨上支的凸度表明已经存在骨盆骨溶解。
