From: Low femoral antetorsion as a risk factor for bony impingement after bipolar hemiarthroplasty
The relationship between ROM and femoral antetorsion. a Flex-antetorsion. Blue dots indicate bony impingement (greater trochanter on the AIIS) and red dots indicate bony impingement (femoral shaft impinges on the ASIS). b Int-R-antetorsion. Blue dots indicate bony impingement (greater trochanter or femoral neck on the AIIS). c Ext-R-antetorsion. Blue dots indicate bony impingement and red dots indicate implant neck to bone impingement
