Clinical application of MSCT in iliac bone measurement

Objective To measure the available length, curvature, and thickness of iliac during iliac graft in adult patients using multi slice CT (MSCT) in order to provide pre transplantation data for the clinical practice. Methods The iliac thickness and available extension at different length and different depth, axial line of anterior iliac crest and iliac crest angle of randomly selected 202 volunteers (male: 101, female: 101) were measured with MSCT. The minimal clinical available thickness was 10 mm. Results There was great difference in iliac thickness in different individuals and between the male and the female. The iliac thickness were (17 17±2 55) mm and (15 87±2 31) mm in the male and the female, respectively. There was no statistically difference in iliac crest angle between the male and the female [(117.59±4.71)°, (116.03±4 98)°]. The axial line of anterior iliac crest was (62 48±5 17) mm in the male and (58 8±4 13)mm in the female. Conclusion The measurement of the iliac thickness, length, and curvature using MSCT is vital to successful operation and decrease of complications. It can also provide the accurate data of shape and extension of the host bone.
