Surgical Technique: Arthroscopic Osteoplasty of Anterior Inferior Iliac Spine for Femoroacetabular Impingement
The anterior inferior iliac spine (AIIS) has variable morphology that correlates with hip range of motion. Subspinal impingement is an extracapsular cause for femoroacetabular impingement (FAI) and is clinically significant because it results in decreased range of motion and groin pain with flexion-...

The anterior inferior iliac spine (AIIS) has variable morphology that correlates with hip range of motion. Subspinal impingement is an extracapsular cause for femoroacetabular impingement (FAI) and is clinically significant because it results in decreased range of motion and groin pain with flexion-based activity.
