Femoroacetabular Impingement

FAI is described as altered bone shape around the hip joint, including cam and pincer forms. Extra bone in FAI is framed as an adaptation to repeated or excessive localized loading rather than direct bone-on-bone contact. Limited movement options may contribute to FAI by repeatedly loading the same regions of the femur or acetabulum. Cam or pincer morphology is presented as a response to persistent loading patterns rather than random bony overgrowth. Improving hip range of motion and movement variability is recommended to redistribute load and potentially reduce symptoms or slow further localized adaptation.
