【摘要】：目的研究骶骨第1椎弓根倾斜角与骶骨耳状面解剖形态的相关性,为骶髂关节骨折脱位经皮骶髂螺钉固定提供解剖学依据。方法 42块干燥成人骶骨,在大体标本和X线影像上分别测量耳状面和第1椎弓根的相关参数,并分析他们之间的相关性。结果耳状面上、下半长轴长比值R1为0.86±0.15,根据其大小可将耳状面分为L型(R11)和f型(R11)。第1椎弓根倾斜角θ为(25.72±6.69)°,R1与θ呈负相关。结论当第1椎弓根倾斜角较小时,其耳状面多为L型,建议手术螺钉的进钉点偏下、小角度向内上;当第1椎弓根倾斜角较大时,其耳状面多为f型,建议手术螺钉的进针点偏上、大角度向内上。
[Abstract]:Objective to study the relationship between the angle of the first pedicle of sacrum and the anatomic morphology of the sacral auricular surface, and to provide anatomic basis for percutaneous sacroiliac screw fixation of sacroiliac joint fracture and dislocation. Methods 42 dry adult sacrum were measured on the gross specimens and X-ray images, and the correlation between them was analyzed. Results on the ear plane, the ratio of the length of the lower half axis is 0.86 卤0.15. According to its size, the auricular surface can be divided into L type (R11) and f type (R11). The tilting angle of the first pedicle 胃 was 25.72 卤6.69 掳R _ 1 and had a negative correlation with 胃. Conclusion when the tilting angle of the first pedicle is small, the auricular surface of the first pedicle is mostly L-shaped. It is suggested that the screw should be tilted inward at a small angle, and if the angle of the first pedicle is large, the auricular surface of the first pedicle is mostly of type f. It is suggested that the entry point of the operative screw is higher and the large angle is upward.
