2024年6月18日 · Femoroacetabular impingement (FAI) syndrome is painful, limited hip motion due to specific morphological abnormalities in the femoral head-neck region and/or …

2022年4月7日 · Pincer morphology refers to an abnormality of the acetabulum, in particular, acetabular overcoverage, which can be focal or global and is one cause of femoroacetabular …

Hip impingement may be caused by a misshapen femoral head, deformed femoral neck, or a hip socket that covers too much of the femoral head. Over time, repetitive “bumping” or …

This results in excessive or abnormal coverage of the femoral head, which can lead to impingement. Acetabular Retroversion The normal acetabulum has an anteverted orientation …

2023年6月26日 · An angle of less than 25 degrees is indicative of poor anterior coverage consistent with hip dysplasia. Pincer deformity will demonstrate an increased angle (greater …

This over-coverage typically exists along the front-top rim of the socket (acetabulum). The end result is that the labral cartilage gets pinched between the rim of the socket and the front part …

Femoroacetabular impingement (FAI) is a chronic hip condition caused by femoral head and acetabular malformations resulting in abnormal contact across the joint. FAI often leads to …

Retroversion of the acetabulum causes over-coverage and restricts flexion of the femoral neck. Coxa profunda deformity (the floor of the acetabulum touches the ilio-ischial line) increases the …

2024年10月15日 · Pincer morphology refers to an over-coverage of the femoral head by the acetabulum. This over-coverage may be global (e.g. coxa profunda and protrusio acetabuli), or …

In pincer impingement, excessive acetabular overcoverage leads to early linear contact between femoral head–neck junction and acetabular rim, resulting in labrum degeneration and …
