Three cases of acute acetabular fracture around uncemented porous-coated acetabular components associated with osteolytic lesions of the pelvis are reported. In each case, the fracture occurred through an area of severe osteolysis that contributed to the structural failure of the pelvis. None of the fractures were associated with significant trauma, and none of the implants demonstrated evidence of loosening before the fracture. When marked pelvic osteolysis develops around the acetabular component of a total hip arthroplasty, the possibility of pelvic fracture must be considered. Total hip arthroplasty patients with osteolysis should be followed with radiographs at regular and frequent intervals. When osteolysis progresses, early intervention should be strongly considered because appropriate treatment may prevent fracture occurrence.
报告了3例与骨盆骨溶解病变相关的非骨水泥多孔涂层髋臼假体周围急性髋臼骨折病例。在每例病例中，骨折均发生在严重骨溶解区域，该区域导致了骨盆的结构破坏。所有骨折均与严重创伤无关，且在骨折前所有植入物均未显示松动迹象。当全髋关节置换术的髋臼假体周围出现明显的骨盆骨溶解时，必须考虑骨盆骨折的可能性。骨溶解的全髋关节置换术患者应定期进行X线检查随访。当骨溶解进展时，应强烈考虑早期干预，因为适当的治疗可能预防骨折的发生。
