ABSTRACT Trochanteric osteotomy, the most extensile approach, is a valuable tool for difficult primary and revision total hip arthroplasties (THAs). Extended trochanteric osteotomy (ETO) is helpful in revision and extraction of well-fixed cemented as well as uncemented fremoral components, facilitates in cement extraction, and also in enhancing acetabular exposure. Tradional posterolateral ETO is initiated at the posterior aspect of the femur. We describe a modification of ETO by an anterolateral approach. The advantage of this approach is that as it preserves an intact musculo-osseo-muscular sleeve comprising of gluteus medius and minimus, greater trochanter, and vastus lateralis it allows physiological reconstruction of hip's soft tissue envelope and thus prevents proximal migration, nonunion of the osteotomy, and abductor lurch, which are the commonest complications associated with an ETO. Anterolateral exposure of hip joint and anterior fibers of gluteus medius, minimus, and capsule reflected as cuff and limbs of osteotomy are marked, and after completing the osteotomy with the help of osteotomes passed from posterior to anterior, the fragment is hooked open on its anterior muscular hinge. Osteotomy is fixed with the help of three to four cerclage wires depending on length of osteotomy. Full-weight bearing and abduction against gravity are only allowed after confirming radiological union of the osteotomy. How to cite this article Kacker S, Singh C, Marya SKS.
