The correlation between the inclination of S1 pedicles and morphology of auricular surface of sacrum
Objective In order to provide anatomic basis for percutaneous fixation using sacroiliac screw by analyzing the correlation between the inclination of S1 pedicles and morphology of auricular surface of sacrum was investigated. Methods The relevant parameters of S1 pedicles and auricular surface were measured in 42 dry adult sacra respectively, then the correlation of the parameters was analyzed statistically. Results The ratio (R1) of long axis of the upper part and the lower part was 0.86±0.15. According to the value of R1, the auricular surface was classified into two types, type L （R1>1） and f （R1<1）. The inclination of S1 pedicles (θ) was (25.72±6.69)°, and the ratio R1 was correlated negatively with inclination θ. Conclusion When the inclination of S1 pedicles is small, the auricular surface is type L, suggesting optimal angle of screw of S1 pedicle is smaller and the optimal point of surgical screws should be lower. When the inclination of S1 pedicles is larger, the auricular surface is type f, suggesting optimal angle of screw of S1 pedicle is larger and the optimal point of surgical screws should be higher.
