Hur får man cam?
Det finns en misstanke om att CAM-förändring beror på en glidning i tillväxtzonen (fysiolys) under puberteten och att PINCER-förändring beror på en dragning (traktion) eller kollision mellan lårbenshalsen och ledpannan, vilket startar en tillväxtrubbning som leder till en utväxt av bennabbar (osteofytbildning).
Vad beror snapping hip på?
Det finns två orsaker till snapping hip. Den vanligaste är att en av senorna som i vanliga fall går bredvid den stora benknölen som finns på höftens utsida, istället glider över benknölen. När senan glider över knölen kan det höras knäppningar och man kan även känna smärta.
What are the MRI findings characteristic of femoroacetabular impingement (FAI)?
Imaging findings of femoroacetabular impingement. MRI findings of changes secondary to FAI within the acetabulum can be seen involving the acetabular bone, labrum, and articular cartilage. Recent research by James et al 24 suggests that a majority of the abnormalities are located peripherally at the labral-chondral transition zone.
What is included in MRI evaluation of the femur for impingement?
MRI evaluation is directed to both femoral and acetabular causes of impingement. The proximal femur must be scrutinized in multiple imaging planes with special attention to the anterior and anterosuperior aspects of the femoral head-neck junction. One or more features (which frequently coexist) are sought for identifying a cam-type deformity:
Is Femoroacetabular Impingement a cause of osteoarthritis?
In recent years, the concept of femoroacetabular impingement has become increasingly recognized as a potential cause of early-onset osteoarthritis in the nondysplastic hip [ 1, 8 ]. In essence, this impingement consists of repetitive abutment between the femur and the acetabular rim during terminal hip motion secondary to reduced joint clearance.
What is femoroacetabular impingement with bilateral acetabular labral tears?
Cam-type femoroacetabular impingement with bilateral acetabular labral tears and chondral loss. Femoroacetabular impingement (FAI) is not a disease, but a common pathomechanical process which occurs when the proximal femur comes into contact with the acetabular rim.
