Impingement of the prominent anterior inferior iliac spine (AIIS) against the femoral neck has recently been described as another type of impingement. The purpose of this study is to provide a distribution of AIIS types using the classification proposed by Hetsroni and thus report on the prevalence of prominent types.
A total of 400 patients were included in the study with an average age 27.3 ± 6.9 years (range 18-40). All patients received a whole-body polytrauma computer tomography (CT) scan in the emergency room (ER) upon arrival. The classification of AIIS proposed by Hetsroni et al., which describes three morphological types, was used. Type II and III were grouped as prominent types. The measurements were performed in all three planes by two examiners.
Male to female ratio was 71:29. Type I was observed in 367 (91.7%) patients. Type II was observed in 31 (7.8%) patients and type III was observed in 2 (0.5%) patients, unilaterally. Prominent types were much more prevalent in men (10.5%) than in women (2.6%). The CT assessment demonstrated excellent intra- and interreliability (overall: 0.926, I/II: 0.906, III: 1.000).
A young population demonstrates a prevalence of a prominent AIIS of 11.5%. Prominent AIIS is more common in men than in women.
突出的前下髂棘（AIIS）撞击股骨颈最近被描述为另一种类型的撞击。本研究的目的是使用 Hetsroni 提出的分类来提供 AIIS 类型的分布，并报告突出类型的患病率。
共有 400 名患者纳入研究，平均年龄 27.3±6.9 岁（范围 18-40 岁）。所有患者在急诊室（ER）到达时均接受全身多发创伤计算机断层扫描（CT）扫描。使用 Hetsroni 等人提出的描述三种形态类型的 AIIS 分类。将 II 型和 III 型归类为突出型。两位检查者在所有三个平面上进行测量。
男女比例为 71:29。I 型在 367 例（91.7%）患者中观察到。II 型在 31 例（7.8%）患者中观察到，III 型在 2 例（0.5%）患者中观察到，单侧。突出型在男性中更为常见（10.5%），而在女性中则较为少见（2.6%）。CT 评估显示出极好的内部和外部可靠性（总体：0.926，I/II：0.906，III：1.000）。
年轻人群中突出的 AIIS 患病率为 11.5%。突出的 AIIS 在男性中比女性更为常见。
