| Background:Yamen point belongs to Dumai,the intersection point of Dumai and Yangwei.It is a commonly used acupoint in the clinic.It is located between the atlas and the vertebrae,the deep part is adjacent to the medulla oblongata,and the upper part is adjacent to the foramen magnum.An acupuncture accident occurred.Atlantoaxial dislocation is a disease caused by abnormalities in atlantoaxial alignment due to various factors,and the anatomical structure has changed significantly.Therefore,the conventional acupuncture safety depth and angle are no longer applicable when acupuncture is performed on patients with atlantoaxial dislocation.It is important to clarify the safety depth and angle of acupuncture for clinical safety acupuncture.OBJECTIVE:To obtain and compare the safety depth and angle of acupuncture at the acupuncture point at the dumb door of patients with atlantoaxial dislocation and patients with normal anatomy.Methods:From January 2010 to January 2018,177 patients with atlantoaxial dislocation(observation group)and 207 patients with normal anatomical structure(control group)diagnosed and treated at the Upper Cervical Spine Research Center of the China-Japan Friendship Hospital,including 191 males For example,there are 193 women.All patients included were of moderate size.The MRI scan of the cervical spine was performed on the sagittal image to measure the safe depth of straight and oblique puncture at the mumen point,and the dangerous angle and safe angle of acupuncture at the mumen point were also measured.Results:The safety depth of the observation group:male straight stab(45.33±5.17)mm,oblique stab(48.58±4.41)mm,female straight stab(44.17±7.80)mm,oblique stab(47.49±7.32)mm,control group safety depth:Male straight stab(47.72 ± 5.06)mm,oblique stab(42.69±5.53)mm,female straight stab(44.63±5.85)mm,oblique stab(39.88 ± 6.18)mm.Observation group men and women have statistically significant oblique safety depth greater than straight piercing safety depth(P<0.05),while control group men and women have oblique safety depth less than straight piercing safety depth(P<0.05);There was no statistically significant difference between males and females in the safety depth of straight and oblique puncture in the observation group(P>0.05).The males and females in the control group had statistically significant safety depths(P<0.05);The depth is less than that of the control group(P<0.05);the oblique-pricked safety depth of the male observation group is greater than that of the control group(P<0.05);the oblique-pricked safety depth of the female observation group is greater than The safety depth of oblique stabbing in the control group was statistically significant(P<0.05);the safety depth of straight stabbing in the female observation group was not statistically different from that of the control group(P>0.05).:In the observation group,the dangerous angle of male direct puncture(13.14±3.99)°,the relative safe angle(10.31±3.23)°,the dangerous angle of oblique puncture(9.09±3.09)°;the dangerous angle of female straight puncture(12.12±2.74)°,Relative safety angle(10.56±2.09)°,oblique thorn danger angle(9.70±2.95)°.In the control group,the dangerous angle of male direct puncture is(7.89±1.59)°,the relative safe angle is(10.21±3.55)°,the dangerous angle of oblique puncture is(16.07±1.77)°;the dangerous angle of female puncture is(6.93±1.45)°,relative Safe angle(10.70±2.94)°,oblique thorn danger angle(14.89± 2.18)°The risk angle of male and female direct penetration in the observation group was greater than that of the control group,and the difference was statistically significant(P<0.05);compared within the two groups,there was no statistically significant difference between male and female in the observation group(P>0.05),but the males in the control group were larger than the females,and the difference was statistically significant(P<0.05).The relative safety angles of men and women in the observation group were not statistically different from those in the control group(P>0.05);the comparison of the relative safety angles between the two groups showed no statistical difference between men and women(P>0.05).The oblique-prick risk angles of men and women in the observation group were smaller than those of the control group,and the differences were statistically significant(P<0.05);the oblique-prick risk angles of men in the observation group were not statistically different from those of women(P>0.05);In the control group,the angle of male oblique puncture is greater than that of female,and the difference is statistically significant(P<0.05).Conclusion:The safety depth of acupuncture at Mummen acupuncture point in atlantoaxial dislocation has changed significantly,and it should be less than the safety depth in clinical acupuncture.In the atlantoaxial dislocation state,the danger angle and safety angle of acupuncture at the dumb door have changed significantly.The straight puncture should be slightly lower in the horizontal direction during the acupuncture.Safety. |
