Outcome Analysis of Hemiarthroplasty versus Total Hip Arthroplasty for Unstable Intertrochanteric Fractures in Elderly Osteoporotic Patients

Hip fractures are common in elderly patients and place significant burden on healthcare system across the world. The demographics of world populations are set to change, with more elderly living in developing countries, and it has been estimated that by 2050 half of hip fractures will occur in Asia. The incidence of proximal femoral fractures has increased due to the higher life expectancy of population. As most patients with intertrochanteric fractures are elderly, operative treatment must be rapid and permit immediate weight bearing postoperatively. The communition, osteoporosis and instability often delay early weight bearing after internal fixation and also affects the prognosis. Also, there is higher incidence of general complication due to prolonged recovery time after internal fixation.
