Abstract
PDF - PURPOSE
To evaluate upper sacral morphology and anatomy of safe zone related to iliosacral screw fixation in Korean.
MATERIALS AND METHODS
100 patients performed pelvis 3D CT scan were evaluated. We used 16 channel CT and analyzed reconstructed image (shaded-surface display, transparent image and reformat image).
RESULT
The angle between superior aspect of S1 body and iliac cortical density is 27.3°, between anterior cortical line of S1,2 body and horizontal plane 24.6°, and between superior aspect of S1 body and horizontal plane is 39.7°. The axis of S1, S2 pedicle is 32.5° and 15.6° toward anteromedial. The area of S1 pedicle according to sagittal plane and sagittal-oblique axis is 310.7 mm2 and 384.8 mm2. Also, S2 pedicle area is increased 163.1 mm2 to 188.4 mm2. The average depth of ala indentation is 5.1 mm and the maximal value is 9.5 mm. Distinct upper sacral dysplasia is 22%, transitional form is 32%.
CONCLUSION
We measured Korean upper sacrum with 3D-CT, found out dysplasia come up to 54%. Considering the frequency of dysplasia, the investigation of anatomy and technique is essential to sacroiliac screw insertion. -

- PURPOSE
To evaluate the correlation of the safe zone of percutaneous iliosacral screw fixation with sacral dysmorphism and sacral alar slope variation.
MATERIALS AND METHODS
We studied the plain radiographs and the pelvic bone CT images of 52 patients. We reviewed each cases in terms of Routt 's dysmorphism and sacral alar slope variation(anterior, coplanar and posterior to inter-ICD line). We divided each cases into narrow and wide groups by the width of safe zone for the transverse 6.5mm cannulated cancellous screw. The data were analysed by McNemar x2-test and Cochran Q-test(p<0.05).
RESULTS
Typical sacral dysmorphism was found in five cases(9%). Four cases with dysmorphism(80%) and eighteen non-dysmorphic cases(38.2%) revealed narrow safe zones. The sacral slopes were anterior in 16 cases, coplanar in 25 cases, and posterior in 11 cases. The safe zone was significantly narrow in the group with anterior slope variation.
CONCLUSION
We could not found definite correlation between sacral dysmorphism and a narrow safe zone because the incidence of dysmorphism was too low in our study which differed from Routt 's report. An anterior sacral alar slope on CT can be a significant risk indicator for potential narrow safe zone and the risk of screw malposition. -
