Example.The sex of four groups of patients, age, body weight, the course of disease, function of nervous system 17 of association of orthopedics of preoperative JOA(Japan point system) comment
Divide and lesion segment number compares, no significant difference (P > 0.05), there is comparability.
2) observational technique
Operative doctor satisfaction.Investigation table of satisfaction degree divide three (position help to appearing, position to the comfortable help of operation,
The help that fluoroscopy during operation is positioned by position), each score value 0～10 points, totally 30 points.Stood after operation terminates by operator surgical doctor
I.e. give a mark.
Cervical region fixing-stable rate.After operation position puts end, on sheet and operation scene-affinity walk crosswise and two sides of stringer
To drawing the position of posture pad, operation terminates to measure immediately to draw the distance that line moves, and is good stability less than 5mm, is more than
It is unstable in 5mm.
Head and neck skin serviceability rate.After operation terminates, when patient is lifted to transport vehicle, rounding nurse in operating room check head
Skin of neck is red with or without pressure, skin have the red and finger pressure skin of pressure do not fade be considered as the most intact.For getting rid of because of the skilled journey of operative doctor
Degree difference causes the impact of operating time factor different in size, and Operation is same operation group doctor and completes.
3) result
The operative doctor satisfaction of A1 group, A2 group, D1 group and D2 group, cervical region fixing-stable rate, postoperative head and neck skin serviceability rate
Be relatively shown in Table 3.Four groups of data are carried out statistical analysis, A1 group, D1 group and D2 group, and A2 group, D1 group and the operation of D2 group
Doctors'satisfactory degree, cervical region fixing-stable rate, postoperative head and neck skin serviceability rate contrast difference the most statistically significant (P < 0.05).
