“…Khang et al 23 showed that femoral anteversion was greater in specimens from Korean subjects (17.9 ) compared with data previously reported on specimens from white subjects, which averaged around 10 of femoral anteversion. The current study by Won et al 10 shows that healthy Korean subjects have femoral anteversion and ischiofemoral distance values similar to those reported for asymptomatic white subjects. Future studies may further elucidate the clinical and radiographic presentation of patients with ischiofemoral impingement.…”

“…Although Won et al 10 provide evidence that the morphology of the hip joint influences the ischiofemoral distance, one must consider the previously described variability between ethnicities. Dudda et al 21 showed that Chinese subjects differed from white subjects by averaging a smaller center-edge angle, as well as having radiographic evidence suggesting greater femoral head asphericity and impingement.…”

“…The subjects in the study by Won et al 10 were from a preoperative group undergoing total hip arthroplasty for osteonecrosis of the hip. Increased femoral anteversion is a risk factor for idiopathic osteonecrosis of the femoral head.…”

“…The study by Won et al 10 helps to establish normative values for the ischiofemoral distance and key characteristics that may influence ischiofemoral distance variability. The combination of structure and movement of the hip impacts the ischiofemoral distance and may ultimately predispose patients to sequelae of ischiofemoral impingement.…”

Ischiofemoral impingement is becoming a more recognized source of buttock pain that occurs as the lesser trochanter of the femur approximates the lateral margin of the ischium. Abnormal bony structure and alignment of the hip joint and/or faulty dynamic movement patterns may decrease the ischiofemoral space and compress the structures that are found within the space, including the quadratus femoris, proximal hamstring tendons, and sciatic nerve. The ischiofemoral space is reduced by structural factors including an increase in femoral anteversion and femoral neck angle. Dynamic assessment of the hip region may include the Craig test and total rotational range of motion of the hip joint, as well as the ischiofemoral impingement test and the long-stride walking test. The combination of structural and dynamic assessment of the hip region may help determine the presence of ischiofemoral impingement and direct appropriate management of the condition.
