(2017) British journal of sports medicine. For initial identification of cam morphology, AP view of the pelvis and a lateral femoral neck view is recommended 1. 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. 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. 1 Femoroacetabular Impingement causes the two bones to rub against each other with movement which over time due to increased friction between the bones causes pain and a decrease in functional … Hip arthroscopy can be a successful intervention used to address this condition. The predilection site for possible injury in cam deformity is the chondrolabral junction of the anterosuperior acetabulum 6. 13. Cam-type femoroacetabular impingement is an anatomic hip condition that can lead to labral pathology, hip pain and arthritis. This condition can be treated with corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, rest and surgery. (2008) The Journal of bone and joint surgery.

The indication for surgery warrants not only morphological changes but also typical clinical signs and symptoms indicative of femoroacetabular impingement 1,9. 20 (1): 32. The normal skeletal anatomy of the hip minimizes biomechanical stressors between the head of the femur and the acetabular rim. J Arthroplasty. The labrum can be crushed under the prominent rim of the acetabulum. 8. Cam morphology refers to an abnormal morphology of the femoral head-neck junction interlinked with an osseous asphericity. 1, 2 In 1975, Harris and coauthors described the pistol grip deformity of the femoral head observed in association with early-onset osteoarthritis.

Arthroscopic cam resection can restore the normal mechanical environment of the hip joint in cam-type femoroacetabular impingement, a new study finds. 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. (2012) Radiology. The location of the abnormal growth determines what type of impingent occurs: 1. {"url":"/signup-modal-props.json?lang=us\u0026email="}. These abnormal bumps can crush the labrum, and collide with the cartilage of the head of thefemur,, leading to joint damage.

Your rating: none, Average: 0 (0 votes) Rate it. 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. Permanente mechanische Irritationen sind die Folge und können zu Schädigungen der beteiligten Strukturen am Hüftgelenk führen. The underlying problem with FAI is a bony abnormality. Not yet completely understood, a combination of several factors seems to cause cam morphology 2-6: The cam morphology is usually most prominent in the anterosuperior position of the femoral head-neck junction 7 usually between 0:30 and 2:30 on the clockface of the hip ref. 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.
