每天朗读一段医学影像学英语文章

Insufficiency fractures commonly involve the sacral ala, pubic rami, femoral necks and supra-acetabular regions.  The ilium may be involved with a linear pattern similar to the more common sacral fractures.  These fractures are often seen in elderly, osteoporotic females but may also occur related to radiation therapy.  Fractures may be unilateral, as in this case, or bilateral.

Radiographs may be normal or demonstrate areas of bone sclerosis or condensation.  The fracture line may be identified, especially when the pubic rami rare involved.  Bone scan and CT features are well known.

【Sacral and iliac insufficiency fractures 骶椎、髂骨不完全骨折】

不完全骨折常累及骶骨翼、耻骨支、股骨颈和髋臼上区。髂骨可能会出现线样骨折,类似骶骨骨折。常见于老年人,骨质疏松女性,也可见于放疗患者。可单侧受累,如本病例,也可是双侧受累。
       平片可表现为正常,或有骨的硬化或压缩。可见骨折线,特别是耻骨支受累时。骨扫描和CT可更好的显示病变。
