Harris lateral approach to hip. A, Iliotibial band has been divided proximal to greater trochanter. A finger has been placed on insertion of gluteus maximus deep to band, and fascia lata is to be incised 1 fingerbreadth anterior to insertion (broken line) without cutting into insertion of gluteus maximus. B, To obtain wide exposure posteriorly and to provide space into which femoral head can be dislocated, a short oblique incision has been made in posteriorly reflected fascia lata, extending into gluteus maximus (see text). Greater trochanter is to be osteotomized (see text). C, Greater trochanter has been osteotomized and retracted superiorly; superior part of joint capsule has been freed; and insertions of piriformis, obturator externus, and obturator internus are to be divided. D, Full circumference of femoral head has been exposed by placing greater trochanter and its muscle pedicle into acetabulum and externally rotating femur. E, Entire acetabulum has been exposed by retracting the greater trochanter superiorly and dislocating the femoral head posteriorly. SEE TECHNIQUE 1.68.
