骶尾骨正常变异的影像学分析

Image analysis of normal anatomical variations in sacrum and coccyx

目的:观察骶尾骨在X线片上的各种表现形态,以期对正常解剖变异有所了解。方法:对120例无骶尾部损伤患者拍摄骶尾骨X线片,由有读片经验的骨科和放射科医师观片,分析其不同的形态变化。结果:骶尾骨有4种不同的形态变异,分别为均匀弯曲型、骶骨成角型、尾骨成角型、尾骨脱位型。结论:正常骶尾骨在X线片上形态有不同变异,在临床上对骶尾骨骨折脱位的患者诊断时,应注意区分是正常变异还是骨折脱位。

Objective: To observe sacrum and coccyx's anatomical variation in X-ray, and to understand normal anatomy variation. Method :Took X-ray of 120 cases un-injury patients and read the image by experience doctor. Result: Four anatomical variation were showed : well-curved type, sacrum angulation type, coccyx angulation type, coccyx dislocation type. Conclusion: Sacrum and coccyx have various anatomical variation in X-ray image, the ceinicians should pay more attention to differentiate the normal anatomical variation from fracture and dislocation.
