Recently, femoroacetabular impingement has been recognised as a cause of early osteoarthritis. There are two mechanisms of impingement: 1) cam impingement caused by a non-spherical head and 2) pincer impingement caused by excessive acetabular cover. We hypothesised that both mechanisms result in different patterns of articular damage. Of 302 analysed hips only 26 had an isolated cam and 16 an isolated pincer impingement. Cam impingement caused damage to the anterosuperior acetabular cartilage…

Bone apposition of the acetabular rim in deep hips: a distinct finding of global pincer impingement.

Later stages of this bone formation cannot be distinguished from the native bone and the labrum may appear to be nearly absent on imaging studies, and the described phenotypes of bone apposition indicate the site of the impingement problem.

Arthroscopic Femoral Osteoplasty/Chielectomy for Cam-type Femoroacetabular Impingement in the Athlete

The underlying pathology of cam-type FAI, the evaluation and diagnosis, arthroscopic treatment, and reported outcomes are reviewed.

Femoroacetabular impingement: prevention or intervention? The sports physician's quandary

Femoroacetabular impingement (FAI) is a mechanical process by which the human hip fails due to pathological contact between the skeletal prominences of the acetabulum and the femur. This repetitive

Impingement femoro-acetabolare (FAI) e sport

Certain clinical tests are suggestive of FAI, but plain radiographs and overall NMR arthrography can assess the degree of impingement and indicate the treatment, and both open and arthroscopic methods can be performed.


The results of this study demonstrate that acetabular stresses can increase as a result of femoroacetabular impingements, which can lead to damage in the hip joint which presents a clinical problem.

Protrusio acetabuli: Joint loading with severe pincer impingement and its theoretical implications for surgical therapy

The protrusio joint resulted in opposite patterns of von Mises stress and contact pressure during walking and standing to sitting, and an overload at the medial margin of the lunate surface was found.

Two mini anterior approaches to the hip joint based on the Heuter and direct anterior approach were investigated to assess their potential for treating FAI and it was found that the two approaches were easy and reproducible.

Os Acetabuli in Femoro-Acetabular Impingement: Stress Fracture or Unfused Secondary ossification Centre of the Acetabular Rim?

The clinical importance is that the presence of an acetabular rim fragment in the non-dysplastic hip must raise suspicion of femoro-acetabular impingement.

Hip Damage Occurs at the Zone of Femoroacetabular Impingement

Femoroacetabular impingement mechanism contributes to early osteoarthritis includinglabral lesions including labral lesions and the extent of joint damage along the acetabular rim was larger intraoperatively than that observed on the images of the 3-D joint simulations.



Femoroacetabular impingement and the cam-effect. A MRI-based quantitative anatomical study of the femoral head-neck offset.

For patients suspected of having impingement of the rim, anatomical variations in the proximal femur should be considered as a possible cause.

Anterior femoroacetabular impingement: part I. Techniques of joint preserving surgery.

Surgical treatment of femoroacetabular impingement focuses on improving the clearance for hip motion and alleviation of femoral abutment against the acetabular rim, and the technique of joint-preserving surgery.

Femoroacetabular impingement: a cause for osteoarthritis of the hip.

It is proposed that early surgical intervention for treatment of femoroacetabular impingement, besides providing relief of symptoms, may decelerate the progression of the degenerative process for this group of young patients.

Anterior Femoroacetabular Impingement: Part II. Midterm Results of Surgical Treatment

Surgical dislocation with correction of femoroacetabular impingement yields good results in patients with early degenerative changes not exceeding Grade 1 osteoarthrosis, but this procedure is not suitable for patients with advanced degenerativeChanges and extensive articular cartilage damage.

Anterior Femoro-Acetabular Impingement Due to Acetabular Retroversion: Treatment with Periacetabular Osteotomy

Periacetabular osteotomy is an effective way to reorient the acetabulum in young adults with symptomatic anterior femoro-acetabular impingement due to acetabular retroversion.

The contour of the femoral head-neck junction as a predictor for the risk of anterior impingement.

Using standardised MRI, the symptomatic hips of patients who have impingement have significantly less concavity at the femoral head-neck junction than do normal hips, and this test may be of value in patients with loss of internal rotation for which a cause is not found.

Acetabular Retroversion is Associated With Osteoarthritis of the Hip

Findings have applicability to understanding the mechanical etiology of hip osteoarthritis, and to surgical technique during periacetabular osteotomy and total hip arthroplasty, because of the statistically significant association between radiographic acetabular retroversion and hip osteOarthritis.

Slipped capital femoral epiphysis: Early mechanical damage to the acetabular cartilage by a prominent femoral metaphysis

It is found that when the anterior femoral metaphysis was level with or extended past the epiphysis, it caused labrum and cartilage damage, suggesting that arthrosis in SCFE can be triggered by early mechanical damage of the acetabular cartilage.

Cross-Table Lateral Radiographs for Screening of Anterior Femoral Head-Neck Offset in Patients with Femoro-Acetabular Impingement

Cross-table lateral radiographs of the hip are useful for screening patients complaining of anterior femoro-acetabular impingement symptoms, as their anterior femoral head-neck offset may be smaller.

Acetabular and femoral anteversion: relationship with osteoarthritis of the hip.

Primary osteoarthritis of the hip, often referred to as idiopathic, may be secondary to mechanical causes and there is some evidence to suggest a congenital etiology for increased or decreased anteversion of the femur and acetabulum.
