Distinctive vertical insufficiency fractures of the pelvis were found in nine osteopenic patients. Each patient had subacute pelvic pain without antecedent trauma. The sacral fractures healed fairly quickly, but the pubic fractures often had a protracted course. Eight patients had combined sacral and pubic fractures; one had only sacral alar fractures. In three patients the sacral fractures preceded the pubic fractures by 3-4 months. All nine patients had skeletal demineralization due to metabolic bone disease, radiation therapy, or multiple myeloma. Recognition of the association between pubic and sacral insufficiency fractures should aid in recognizing the diffuse nature of the skeletal disease so that unnecessary biopsy of the fracture sites can be avoided.
在9例骨质减少患者中发现了独特的骨盆垂直不全骨折。每位患者均有亚急性骨盆疼痛，且无前驱外伤史。骶骨骨折愈合较快，但耻骨骨折病程往往迁延。8例患者同时有骶骨和耻骨骨折；1例仅有骶骨翼骨折。3例患者骶骨骨折比耻骨骨折早3 - 4个月。所有9例患者均因代谢性骨病、放射治疗或多发性骨髓瘤导致骨骼脱矿质。认识耻骨和骶骨不全骨折之间的关联有助于认识骨骼疾病的弥漫性，从而避免对骨折部位进行不必要的活检。
