经椎弓根-肋骨结构单元途径置入螺钉安全角度的应用解剖学测量
Applied Anatomy Measurement of Safe Screw Placement Angle from the Pedicle of Vertebral Arch-Frame Structure Unit Way
摘要
Abstract
Objective To provide the anatomical basis for clinical safe screw placement by measuring the safe screw placement angle from T1 - T10 thoracic pedicle-frame structure unit way in adult body specimen. Methods 15 cases of normal adult body specimens, including 9 cases of male, and 6 cases of female, aged 18 ～ 60 years old, average age was 40. The T1 - T10 thoracic vertebras of the body specimen were transected along the pedicle of vertebral arch-frame plane, and we measured the transverse diameter of the T1 - T10 the pedicle of vertebral arch-frame structure unit, and the minimum and maximum safe angle between the sagittal plane and the screw placed from the pedicle of vertebral arch - frame structure unit way. Results The transverse diameter of pedicle of vertebral arch-frame structure unit decreased gradually from T1to T4, and increased gradually from T5 to T10. The range of safe screw placement angle was widest at T1 and T2, followed by T5 - T10, and was narrowest at T3 and T4. There was no significant difference in safe screw placement angle between T1-T2 and T5 - T10 (P > 0.05) , while there was a significant difference between T2 and T5 (P < 0.05). There was no significant difference in safe screw placement angle between the male and female (P > 0.05). Conclusion During placing screw from the pedicle of vertebral arch-frame structure unit, the screw placement angle should be adjusted according to the range of safe screw placement angle at different segmental pedicle of vertebral arch - frame structure unit.关键词
