Abstract:

Objective

To compare the anatomical parameters about anterior inferior iliac spine at different ages (18-40, 41-60, ≥ 61).

Methods

155 normal subjects (male, 115; female, 40) were enrolled, and the maximum length, width, height, surface area and volume were all measured and compared.

Results

The maximum width (41-60 years, 12.0±1.9 VS 9.5±1.1 mm; ≥ 61 years, 12.0±1.8 VS 9.5±1.6 mm), surface area (41-60 years, 444.11±139.24 VS 328.96±92.64 mm2; ≥ 61 years, 469.03±132.26 VS 326.26±118.32 mm2) and volume of the anterior inferior iliac spine (41-60, 910.19±452.34 VS 577.04±259.51 mm3; ≥ 61 years, 989.09±442.99 VS 482.47±254.34 mm3) in males (41-60, ≥ 61 years old respectively) were significantly higher than those in females at the same age group, and the differences were significant (P<0.001). In the age group ≥ 61 years, the maximum height was also statistically significant in males and females (P=0.007). Anatomical parameters compared in different age groups (18-40, 41-60, ≥ 61 years old) were not statistically significant in men and women. The most commonly observed type of anterior inferior iliac spine was Type 1 in all three male or female ages.

Conclusions

The morphology of the anterior inferior iliac spine is relatively stable and has no significant correlation with age, but the volume and surface area are significantly different in the same age group with different genders. In addition, the low anterior inferior iliac spine (Type 2) does not necessarily lead to acetabular impingement syndrome in normal people.
