绝经后脊柱原发性骨质疏松椎体压缩的CT表现

目的:分析绝经后脊柱原发性骨质疏松椎体压缩的CT表现。方法:对X线诊断、临床证实的30例绝经后脊柱原发性骨质疏松患者椎体压缩的CT表现进行回顾性分析。结果:81个椎体表现为压缩变形,其中凹陷形48个,楔形27个,扁平形5个,椎体内骨折线不明显,骨密度均匀减低,骨皮质变薄,骨小梁稀疏。结论:绝经后脊柱原发性骨质疏松椎体压缩是一种退行性改变,仅形态改变,椎体内未见骨折线。CT检查对椎体压缩改变的鉴别有一定的价值。

CT Appearances of Vertebral Compression with Primary Spinal Osteoporosis of Patients with Postmenopausal

Objective To analyze the CT appearance of centrum compression in postmenopausal patients with primary spinal osteoporosis.Methods 30 postmenopausal cases with primary spinal osteoporosis and centrum compression,which confirmed by X-ray film and clinical data,were enrolled in this study.CT appearance of centrum compression was retrospectively analyzed.Results We totally found 81 collapsed centrums,including concave type(n=48).wedge type(n=27)and tabular type(n=5).All the compressed centrums depicted even lower attenuation with papery cortical bone and notable sparse trabeculae;Where as,the fracture line was not found in all compressed centrums.Conclusion Primary spinal osteoporosis in postmenopausal patients is a degenerative disease.Centrum compression associated with it only has morphologic abnormalities,which do not demonstrate fracture line.CT exam has certain values in differentiating various centrum compressions.
