截瘫患者髋臼皮质双边征的观察

Double cortical line image in the acetabulum in paraplegia

本文报告了对６０名截瘫病人骨盆平片的观察结果，发现有３５例可在两侧髋臼顶部观察到皮质双线征。作者认为，皮质双线征系脊髓损伤后所发生的废用性骨质疏松的Ｘ线征象，并对其形成的原因及影响因素进行讨论。

The pelvic radiographs of 60 patients with paraplegia and quadriplegia were reviewed and double cortical line in both sides of the acetabular roofs was found in 35 patients. It was concluded that the double cortical line was a radiologic sign of disuse osteoporosis after spinal cord injury. The etiology of double cortical line sign and related factors were discussed.
