Anterior Inferior Iliac Spine Morphology: Comparison of ... - AJR
2018年11月7日 · The objective of our study was to compare anterior inferior iliac spine (AIIS) morphology in symptomatic hips with femoroacetabular impingement (FAI) and in asymptomatic hips, determine the prevalence of impingement morphology in patients with a radiographic “crossover” sign, and identify potential risk factors for having impingement morphology.
Anterior Inferior Iliac Spine Morphology Correlates With Hip ...
We evaluated three-dimensional CT reconstructions of 53 hips (53 patients) with impingement and defined three morphological AIIS variants: Type I when there was a smooth ilium wall between the AIIS and the acetabular rim, Type II when the AIIS extended to the level of the rim, and Type III when the AIIS extended distally to the acetabular rim.
Anterior Inferior Iliac Spine (AIIS) and Subspine Hip Impingement
2016年6月3日 · Abnormal morphology of the anterior inferior iliac spine (AIIS) and the subspine region of the acetabular rim are increasingly being recognised as a source of symptomatic extra-articular hip impingement. This review article aims to highlight important differences in the pathogenesis, clinical presentation and management of extra-articular hip ...
Anterior Inferior Iliac Spine Morphology Correlates With Hip
2013年2月15日 · We evaluated three-dimensional CT reconstructions of 53 hips (53 patients) with impingement and defined three morphological AIIS variants: Type I when there was a smooth ilium wall between the AIIS and the acetabular rim, Type II when the AIIS extended to the level of the rim, and Type III when the AIIS extended distally to the acetabular rim.
Anterior Inferior Iliac Spine Bone Morphology in Hip Dysplasia and …
2016年2月16日 · The AIIS morphology was also classified into 3 type variants according to the previously reported classification system. (type I: there was a smooth ilium wall between the AIIS and the acetabular rim, type II: the AIIS extended to the level of the rim, and type III: the AIIS extended distally to the acetabular rim)
The prevalence of a prominent anterior inferior iliac spine
2019年2月15日 · Hetsroni variants of AIIS are shown in Fig. 1a–c. Type I variant of the AIIS was defined as a smooth ilium wall between the caudal level of the AIIS and the acetabular rim (Fig. 2). Type II was defined as bony prominences on the ilium wall extending from the caudal area of the AIIS to the acetabular rim or sitting directly at the rim (Fig. 3 ).
We characterized AIIS morphology in patients with hip impingement and tested the association between specific AIIS variants and hip range of motion.
Intra-articular Anterior Inferior Iliac Spine Avulsion with Hip ...
4 天之前 · These incidents typically involve an iliac variant of anterior superior hip dislocations, where the femoral head is forced out of its socket, resulting in the tearing of the iliofemoral ligament or avulsion of the AIIS 4, 6, 7. In our series of cases, each instance involved an anterior hip dislocation accompanied by avulsion fractures of the ...
A comparison between ultrasound-guided AIIS injection and …
2022年12月12日 · The classification of anterior inferior iliac spine (AIIS) morphology via three-dimensional CT is controversial. To propose a method for ultrasound-guided AIIS injection as a way to diagnose SSI and evaluate the accuracy of radiography methods, including 3-D CT and MRI, as well as intraoperative findings.
Anterior inferior iliac spine morphology correlates with hip range …
2013年8月1日 · When the AIIS is classified into three variants based on the relationship between the AIIS and the acetabular rim in patients with impingement, Type II and III variants are …
