Bipolar hemiarthroplasty for intertrochanteric fracture is indicated for patients of more than 80 year old, thus the organic or systemic malfunctions should be corrected during perioperative period. Meanwhile, retaining of lesser trochanter and reconstruction of calcar femorale are of vital importance for improving periprosthetic biomechanics and reducing local complications.
