Das Femoroazetabuläre Impingement, kurz FAI, beschreibt ein orthopädisches Phänomen, in dessen Rahmen es durch morphologische Veränderungen an proximalem Femur und/oder Acetabulum während Hüftgelenksbewegungen zu einem abnormen Kontakt zwischen Oberschenkelkopf/-hals und Hüftpfanne kommt. Die Hüfte ist also bei bestimmten Bewegungen oder Positionen blockiert. Das Hüftimpingement heisst in der Fachsprache femoroacetabuläres Impingement, oder kurz FAI. 2010; 92 (14):2436–44. the aim of this study was to evaluate preliminary clinical and radiographic results of arthroscopic treatment of cam-type femoroacetabular impingement (FAI).thirty-eight patients underwent hip arthroscopy for cam-type FAI between 2009 and 2012. Background: Femoroacetabular impingement is a cause of hip pain in adults and is a possible precursor of osteoarthritis, with the cam type of impingement being the most common. Griffin DR, Dickenson EJ, O'Donnell J, Agricola R, Awan T, Beck M, Clohisy JC, Dijkstra HP, Falvey E, Gimpel M, Hinman RS, Hölmich P, Kassarjian A, Martin HD, Martin R, Mather RC, Philippon MJ, Reiman MP, Takla A, Thorborg K, Walker S, Weir A, Bennell KL.

Symptomatic femoroacetabular-impingement with cam morphology can be treated conservatively or surgically. Femoroacetabular impingement (FAI) kan give anledning til hofte- og lyskesmerter (Philippon et al. Unbehandelt entwickelt sich eine FAI häufig zu einer Coxarthrose.

Hip disease in the young adult: current concepts of etiology and surgical treatment. The abnormal growth can occur near the femoral head, the acetabulum, or both. In cam impingement, the round and spherical form of the femoral head turns into an egg-like form (similar to the cam of mechanical machines). It is one possible causes for femoroacetabular impingement. It occurs when the ball shaped femoral head contacts the acetabulum abnormally or does not permit a normal range of motion in the acetabular socket. 51 (22): 1605-1610. 280 (2): 351-69. In cam impingement the femoral head is not round and cannot rotate smoothly inside the acetabulum.

Larson CM, Stone RM. A cam impingement occurs when excessive bone grows at the edge of the femoral head, where it meets a part of the femur called the femoral neck. Cam deformity causes increased shear forces at the chondrolabral junction, possibly leading to the following 1-3: The deformity usually involves the anterosuperior aspect of the proximal femur more precisely the head-neck junction and is characterized by a loss of sphericity of the femoral head 4  and a flat or convex in cases even ‘bumpy‘  head neck-junction 1-6. Check for errors and try again. Femoroacetabular Impingement is a pathological condition of the hip in which there is growth of an extra bone within the bones of the hip joint which give the hip an irregular or deformed shape. (2013) Current reviews in musculoskeletal medicine. However, the shape of the bones itself do not cause pain. Clohisy JC, Beaulé PE, O'Malley A, Safran MR, Schoenecker P. AOA symposium. J Arthroplasty. Impingementsyndrom. There are three described types of femoroacetabular impingement: Cam Impingement ‘Cam’ type impingement describes a ‘bump’ on the surface of the femoral head (ball) which jams on the rim of the (acetabulum) socket. Pincer . 2010;92(14):2436-2444. Athletes in certain sports might be more likely to develop femoroacetabular impingement. There are three types of femoroacetabular impingement, depending on the location of the bone spurs. (2018) Journal of orthopaedic research : official publication of the Orthopaedic Research Society. 4. cysts or degenerative changes, loss of sphericity or a bump at the femoral head-neck junction especially in the anterosuperior location, >55° considered a risk factor in the anterior position, >60° in the anterosuperior position* is a recommended threshold, improved detection of acetabular chondral defects, better sensitivity for the detection of labral tears, description of abnormalities in the femoral head-neck junction: bump, cysts, associated findings e.g. Klicke hier, um einen neuen Artikel im DocCheck Flexikon anzulegen.

Hip arthroscopy can be a successful intervention used to address this condition. (2016) British journal of sports medicine. CHAPTER 4 Cam-Type Femoroacetabular Impingement. Pincer type is caused by an excessive coverage by the acetabular cavity toward the femoral head (Picture 5.2). A higher incidence of cam-deformity has been found in high-impact sports 1-6: Cam morphology itself can be and remain asymptomatic or can cause clinical signs and symptoms as typical motion or position-dependent hip or groin pain and is then referred to as femoroacetabular impingement 1,2.
